Reddit mentions: The best nail growth products

I would personally not recommend acrylics. Even before I came out as trans I decided to get acrylics because it was easier than natural nail maintenance for guitar (which is what I went to school for).

I used acrylics for about a year or so, and they really destroyed my natural nail underneath; even when I went to a pretty expensive and well known spot for nails. If you value the health of your natty nails, it isn't worth it. Mine are better now but took about 4 months to heal.

What I WOULD recommend otherwise is the following:

https://www.amazon.com/Sally-Hansen-Grow-Nails-0-45oz/dp/B000FVB24M

I take VERY good care of my nails now, and this stuff has done wonders for them. It is very cheap and lasts for a long time. I put it on once a day, and have only broken one nail since mine healed up from the acrylics (my car door has always been out for them).

Hope this helps!

EDIT: Also, just in case you still want to get the acrylics I figured I would answer your other questions since I have spent so long in nail salons at this point.

To look for one, make fucking sure you read reviews. Some places are NOT up to health code and are even worse for your nails (some can lead to infection). You want to make sure that they are using the highest quality products. Make sure that they have a clean and comfortable environment. It is pretty apparent going inside whether a place is good, great, or terrible just by how they organize and maintain the store.

The process is pretty simple. Sometimes it can hurt if they aren't very good. The process differs place to place based on what they use, but generally for acrylics they will file down the top of your nail, make the acrylics by combining stuff that I don't know what it is, and pop it on your nail. They ask about shape and length, and then file it for you. As a warning, the day after I first got acrylics it hurt VERY fucking badly. I could barely use my fingers; but it went away within the day and never happened again. I imagine my nails were just pulling up a little bit on my fingers.

It doesn't take long, maybe like 30 - 40 minutes at the most?

I never really got colors, but I am almost certain they could apply it for you if you asked (I would probably tip more because I am self-conscious about stuff like that).

As far as etiquette goes, I would just leave a solid tip and thank them. It is very akin to getting your hair done in that way. Some of them will talk if you want (Many of them at cheaper places don't talk ever though), and if they sense you just want to chill will only ask you direct questions about what you want done. My hands always shook when I did it and they made fun of me a lot hahaha. We got along really well because I went there ~every 2 weeks to a month.

Hope this helps too!

Hey Wyld.

Good luck on this, as you will need it. It is super difficult to quit. I'm about two months clean, though. I've posted a few times the method that worked for me and hopefully it can work for you, too, as I had the exact same issue.

I bought this stuff: http://www.amazon.com/Mavala-Stop-Biting-Sucking-0-3-Fluid/dp/B0000YUXI0 and put it on my fingernails and cuticles. I reapplied every other day. This stuff tastes super bad, but it worked for me. I wore it for about two weeks total and I haven't had an irresistible urge to bite since then. It still goes through my mind pretty commonly, but it is now easy to win that battle with myself.

I strongly recommend giving this a shot and letting me know how it does for you. I wish you all the best on this, as it is a awful affliction to deal with. Good luck.

Hi! I just quit biting about four months ago. Some things to make sure you do (aka learn from my mistakes):

1. Find the root of the problem. Do you bite because of anxiety or nervousness? Are short nails just easier for you to manage? After you break down the cause, work on managing the habit. Most people can't quit cold turkey and that's fine.
   
   
2. /u/emariesaywhat has a great suggestion, chewing gum. Keeping your mouth busy aside from biting at your fingers will help so much. I personally chew gum and eat sunflower seeds constantly (honestly you would think I just quit smoking) but if you have bad teeth, maybe stay away from these methods. My teeth are terrible but I've already built up the habits of chewing gum and eating seeds so I doubt I will quit now since I am afraid I might go back to biting my nails. It's a huge battle, you've got to find what works for you.
   
   
3. Take care of your nails and hands. I really can't emphasize this enough. I thought if I quit biting I would have beautiful nails and all my problems would be gone. I took no measures to keep my nails healthy and once they were long enough to be proud of, all ten of them broke, some multiple times. Keep yourself hydrated, invest in good cuticle cream or oil (I use this and I love it, also I got it for 5 bucks from Target), file your nails and do not peel them. Also avoid picking off nail polish if you can, it will also strengthen your nails. Use lotion after showers/washing dishes/swimming etc and also before bed. I really love Bath & Body Works hand cream an Cerave cream. Try to avoid pure acetone for nail polish removal unless you moisturize immediately after.
   
   Sorry for the wall of text! I hope this helps and good luck to you! It's a really tough habit to break but you can do it!!! :)

My favorite book is a toss up between Jane Eyre and ... well damn, I can't remember the name but it's a Dickens book! The one where the main character's mother dies shortly after giving birth to his younger sister (I think it's a sister).

About me: There was a time when a good, one word description of me was "tenacious". I'm working at getting that back.

My ideal gift would be a gift card OR, if you don't want to do gift cards, this nail stuff on my high priority list.

Thank you for the contest!

Hey im a nail technician and used to be a horrid nail biter. I've coached many through the habit! Everything these ppl said is true but im going to provide you with some links:

1- Nail file - you dont need a glass one obv but they last forever and are more sustainable.

2- Cuticle Nippers- I would, like u/deskais said, keep them with you all the time for a while and use that when you have a hang nail or rough cuticle you want to pick at. This one is a pretty inexpensive pair that comes with a cuticle pusher to push your cuticles back with.

3- Disgustig nail polish - I've heard tales of people chewing through it but that is mind boggling to me. It tastes awful and will at the very least remind you if you are biting at them subconsciously. There is another brand called "stop the bite" but it wears off and isn't so bad. This one stays on until you remove it.

4- Cuticle Cream. This one is important and would be my #1 choice if you only picked one. Moisturize that shit every day. Keep it on your nightstand or in your car so you dont forget. If they aren't dry, there will be nothing to pick at and they will look so much better.

Id also get a professional manicure just to see how they do it and then that will help you learn how to do it yourself, and it will clean them up and then all you have to do is keep it up with at home care.

​

Good luck! Id love to see a followup post in a month if you remember.

Hi there :) There's this nail polish that tastes icky but looks like a clear coat in order to deter biting. It helps when you don't even know you're doing it. Kinda tastes like ear wax. Hope it helps!

go to amazon and buy "mavala stop" i swear its the best cure for nail biting. Mine used to be so bad it would hurt and bleed all the time but one coat of this stuff works perfectly for about a week. I guarantee you that you will stop biting with this product it tastes horrible when it gets into your mouth, thats the secret...you'll train yourself, much like pavlov did to his dog! Good luck!

Edit2: 4 1/2 stars with almost a thousand reviews? i'd say majority are happy with the product (like i am)

Yep, dry skin. I recommend a thick cuticle cream. My favorite is Hard as Hoof, which is technically a nail growth/strengthening cream, but it's cheap, ULTRA hydrating, smells nice, and makes your cuticles look and feel amazing.

FYI, if you suffer from brittle/soft/peeling nails, this is also great.

I love short work weeks

It is always awesome when a holiday falls on a work day when you can get it off. Yay for shorter work week. Thanks for the contest.

Bingo. There are commercial products as well meant to stop nail biting/thumb sucking. They come with nail polish applicators so it might be a little easier to work with and easier to reapply on to go than something like vinegar. Can't attest to the smell of it. Here are three that have good reviews on Amazon, ranging in price from low, middle and high.

Or, if you like the look of painted nails, I've heard some people say that worked for them. They didn't want to ruin their manicure by biting their nails. This seems less effective to me though because nail polish will inevitably chip regardless and may tempt a biter.

My nails peel ssooo much. I use nailtek 3 part system and my nails are doing much better... they’re not as gorgeous as everybody else’s, but pretty damn good for mine! The oil included has been the best I’ve used too.

Hard as Hoof is a hand cream you rub into your nail beds and under your nails. Here is my process:
Remove polish. Wash hands. Hard as Hoof all over them. Wipe off excess. Play with animals for an hour or so. Wash hands. Dinner and other home such things. 1 layer of Nail Envy 1 layer of Rejuvicote.(Though I haven't had any Nail Envy for months and my nails are still super strong). Polish. I have never used it as a top coat or on top of any other polishes. I change my polish every 2 days or so. If I'm going "naked" I'll add a layer of Rejuvicote daily, but that's not too often. I do, however, keep a jar of Hard as Hoof in my desk at work and I apply it several times a day because my hands get really dry shuffling papers. It smells like amaretto and I love it.

I used to work in advocacy at The Arthritis Society in Canada, and I thoroughly recommend The Arthritis Society in the US. They're an amazing resource, and there are good treatment options for psoriatic arthritis (and all other inflammatory arthritis conditions, of which there are so many). Do you have a rheumatologist already?

I used to have horrible nails and what saved mine is called Pink Armor. I've tried many other gel base coats and none compare to Pink Armor. I get mind at Bed Bath and Beyond, but it seems to be available in a lot of other places and online. Good luck!

Hey congrats! You're doing great! I used to bite my nails for years. What helped me was this nail polish that tastes absolutely horrible if you go to bite your nails. It worked great for me, hope this helps!

\u\nixygirl recommended rejuvacote to me and I've been using it everyday. It just kinda soaks into the nail, doesn't build up like opi nail envy. This stuff is working great for me. I have peeling nails too, and this stuff seems to help keep them together. Here's the link to amazon http://www.amazon.com/Duri-Cosmetics-rejuvacote-Rejuvacote-0-61oz/dp/B000G33KEO/ref=sr_1_1?s=beauty&ie=UTF8&qid=1397573323&sr=1-1&keywords=duri+rejuvacote

Good luck!

When you get acrylics applied, they rough up your nails, which removes some of your nail layers. When you ripped them off, you removed more layers of your nail. (Next time you can soak them in acetone... file the acrylic down as much as possible with a rough grit (180) nail file and then apply acetone to a bit of cotton ball and wrap your finger in aluminum foil to keep the acetone from evaporating. Wait. Check it every 5-10 min to gently scrape off any loosen acrylic until your nails are clean)

There's no way to automatically fix them from peeling/breaking/cracking when they're so thin and damaged. They will take months to grow out the damage completely. In the mean time, you can file them with a gentle, fine grit (400/600) file to smooth/buff off any snags or ragged pieces and keep them short. Then use base and top coat (a nice, thick, quick dry) to give them some strength/protection. Some would recommend using OPI Nail Envy or Nail Teks. Though, to be honest, ANY sort of polish covering the damage will help. Make sure you remove and reapply whatever you decide to use when it starts to lift/peel off.

And use plenty of cuticle oil. Bliss Kiss, Ever After Cuticle Oil and Crelly, Chirality, and Cuter Cuticles, and are some of my favorite brands for cuticle oil. (You could likely find Burt's Bees in stores.) Or you can be boring and just use straight jojoba oil mixed with a little vitamin E. But whatever you find to use, cuticle oil 2-4x a day.

Lifelong nail biter here. I tried Mavala Stop and it worked for a while. It's nice to see your nails grow and I even had to use a nail clipper once! I did eventually relapse, but I wish you the best.

I've never used Nail Envy, I'm dying to, but I do use Millionails! It works well, I have no complaints! I used to wear it over my bare nails, without anything over, adding a new coat every couple days, and now I use it as a base coat. I can't really compare it to Nail Envy, but my nails are super strong now!

Sometimes, after a long shift at work washing dishes etc, my nails might feel a little weak, so I use Hard as Hoof's Nail Strengthening cream before I go to bed, and a few times throughout the day, too!

Hope this helps!

No, you wouldn't slather it all over your hands - it goes on like clear nail polish. But that stuff tastes awful, and the taste will probably get all over your hands anyway, especially the cuticles. I don't remember it smelling like anything.

I would recommend that you ask your pharmacist, but this is an example of what I found online: http://www.amazon.com/gp/aw/d/B0000YUXI0

Good luck!

For me, honestly, I just realized that two of my incisors were so worn down from biting my nails that they couldn't touch anymore when I bite, so I just quit cold turkey. As /u/rjjm88 said, if you have something good to replace it with for the auto-oral response (something to chew on when you're nervous/stressed), it helps out a ton. I actually work at a cigar shop and smoke quite a few cigars, which I inevitably end up chewing on as I smoke them. Not that I recommend that, but as said, have something you can nibble on handy and it'll help a bit. There's also stuff like this,, though that gets a little extreme.

Nailtiques is my HG nail treatment. Formula 2 is the one that seems to really help peeling nails. Moisture should help the skin around your nails. Regular lotion is good; others like oil.

There are products designed to prevent nail biting that will help short term. Getting manicures is supposed to help too. It will really help if you can figure out why you bite your nails, though. That way you can deal with the root cause if it's something like anxiety, replace with something healthy if it's a habit when you're bored, etc.

When I was a kid, I used to bite my nails. My mom thought it was the worst thing in the world, so she tried everything she could think of.

One of them was an anti-nail-biting nail polish, which did help for a bit. It tastes bitter, so when you unconsciously put your hands in your mouth, you realize it and stop.

Here are a few I found from a quick Google search:

CVS $5

Amazon $10

Walmart $3

I usually buy everything at Amazon, but it's the most expensive in this instance. I think a trip to the local pharmacy might be quicker and cheaper, in any case.

Oh, and the nail biting? Silly mom... it went away when I gained confidence in myself and my abilities (I was a nerdy little kid and my mom helped wimp me up by mothering me to death.)

I only mention that last bit because perhaps there's a psychological root to your dilemma.

The nail polish may help in the immediate sense, but if you ask yourself where the behavior is coming from, you might end up solving a bigger issue for yourself.

It's hard to tell someone how to care for their nails. You have to find what works for you because everyone is different. Here are a couple things that work for me. Use the finest glass file you can find and buff the ends with very fine sandpaper (I use 1500 grit) every day and do not skip a day. I also use two creams Hoofmaker as a moisturizer throughout the day and Hard as Hoof when I'm not playing.

I would also recommend picking up Scott Tennant's Pumping Nylon and Christopher Parkening's guitar method books. Refer to the sections about nail care.

I've had some success with this stuff. A few months after I stop using it, I do relapse to some extent. I'm definitely better than I used to be though, and never bite to the extent that I once did (i.e. like the thumb in the image).

I would love this most of my makeup list is add-ons sadly. I have the following items on my wishlist: One, Two, Three, Four, Five makeup wise, I also have a game that is an add-on here. Those Himalaya's of the mind! Thank you for the contest!

https://www.amazon.com/Mavala-Stop-Biting-Sucking-0-3-Fluid/dp/B0000YUXI0

This stuff is pretty awesome. It's worked decently well for me.

Use a strengthener on your nails. If you have weaker nails they bend easily, and that causes first the teeny cracks you're seeing (you flex the nail and the polish cracks instead of flexing too). My mom had the same issue and this stuff fixed it for her after a few weeks of use!

I know gel polish is rad, but if you're like me and can't afford the time or money to get them done every couple weeks this might be a good option.

Duri Rejuvacote will strengthen your nails and prevent peeling, also makes a great top coat. I heard a story about a chemo patient who used it to grow her nails back quickly. Just be careful not to get it on your cuticles bc it will make them grow like crazy too.

Would love to try this to see if it helps me stop biting my nails!

Study Sunday :)

I've tried several and this one has given me the best bang for my buck. You can get it at wal mart too and some walgreens or CVS have it too.

I have tried some other ones with much less success.

There is specialty nail Polish you can get specifically for stopping nail biting. It tastes horrible like I'm talking horrible. Something like this

Here are some really good tips from dermatologists.

Here

The one I found that helped me when I was stopping was the last one try stopping gradually so one nail at a time so both thumbs then your thumb and second fingers till you have developed healthy habits. It's going to take a lot of patience so don't give up if you fail the first couple of times. It is a habit and habits are hard to break or replace but it is possible I was a chronic nail biter for 10years I replaced it with playing with my hair and when I'm stressed I tap out a tune on my fingers it still involves my hands but I'm not wrecking my nails or fingers.

This ladies blog is genius it is honest and she herself was a sufferer and knows how it feels to fail and what you go through having bad nails and the disappointment. She is also realistic and tries to find the route of the issue and give you realistic ways to stop the biting.

Here

But most of all don't give up we are all here to support you and I'm sure your partner would love to support and help you.

Good luck ♡

I have also been a chronic nail biter for as long as I can remember. Ive been pretty good the past few years about it but still have weak moments where I go ham on one particular nail. My nails are weak and break easily as well. I honestly can say that Pink Armor has saved my nails. I don't work or rep for the company, I just happened upon the nail polish at Ross one day and started using it. 2 coats for my base coat and then 1 coat of the Essie ridge filler every time I paint my nails. My nail polish never chips with it on and I can get about a week out of my manicures before I get bored with the color and want to change it. You can find this stuff on Amazon or at Target in the As Seen on TV section by I always get mine at Ross because its $5 instead of $10. Again, I don't have any affiliation with this nail polish and would never purchase directly from them (anything advertised in those As Seen on TV type of ads seem so sketch) but the stuff has made my nails so much stronger and repaired the damage I had done from my years of biting them. Hope this helps!

I use Duri Rejuvacote. I actually stumbled onto it at Walmart. It's actually rated higher than OPI nail envy on Makeup Alley. I'm sure either would be good though. I've been using the Rejuvacote for about 3 weeks now and have had no breaks, tears or anything. I love it! I've never had my natural nails this long or strong before.

For the finger sucking: My four year old doesn't suck his fingers while he's wearing [Thum] (http://www.walgreens.com/store/c/thum-b-sucking/nail-biting-liquid/ID=prod922-product) . The only trick is consistency. If that turns out to be too weak, Mavala Stop has better [reviews on Amazon] (http://www.amazon.com/Mavala-Stop-Biting-Sucking-0-3-Fluid/dp/B0000YUXI0/ref=sr_1_1?ie=UTF8&qid=1413493717&sr=8-1&keywords=thum) but it sounds like it might be too strong in some cases.

I was exactly the same for like 15 years. until i found this stuff:

http://www.amazon.com/Mavala-Stop-Biting-Sucking-0-3-Fluid/dp/B0000YUXI0

this nasty shit is like magic. i had this on for a week, (only 1 application) and I slipped once or twice, but that awful taste does something to your subconscious and I haven't had the urge to bite at all since. any small urges are easy to resist now. I would offer to give you the bottle, but I want to save it for a while just in case.

1: oh hey errmagerd! Thanks for the contests!

2: such nail art - Star Wars mani. I worked really hard on this one.

3: this is how we do it - I wish I had a secret for nail care! I've tried SO many products recommended here (and given them each a month of use) with no luck - but maybe one will work for you: Sally Hansen Complete Care, OPI Nail Envy Original, OPI Nail Envy Maintenance, ORLY Bonder, and Nail Tek. Still my nails peel at the tips. I really don't know what to do, aside from keeping my nails trimmed short or not polishing at all. I'm trying this by Sally Hansen, now. I've only been using this for one week, so it's too early to tell. I do use cuticle oil, and like most people here, I use Emerald & Ash (as well as Rainbow Honey & Essie Apricot Oil) - though, I'm not as religious about it as I probably should be. I tend to wait until my cuticles look in rough shape. >.>

My dog used to eat electrical cords all the time. Surprisingly even chewing through them never shocked him (not that I'd recommend it...just saying)

2 things that totally worked for us.

1. Stop Nail Biting Polish painted on the cords. It tastes awful. It's not tempting after the first lick.
   
   
2. I cut a super hot pepper (serrano) and rubbed the pepper oil up and down the length of the cord. It didn't last as long as the polish, but it was cheaper and WAY more effective. He would still check them out with the polish, but after the serrano he was done with cords forever.

yeah sure!

I'm seeing results already after a good week of use.

Not that you necessarily looking for solutions to stop, but I'd recommend something like this. It tastes bitter and encourages you to keep your nails out of your mouth.

This was my savior Good luck!

I wear these things. It takes just a dozen of them to hold my hair up in a giant cinnamon bun larger than my spread-out hand.

If you search for Amish hairpins you can find some smaller sizes. I haven't tried the straight-sided pins, just those crinkled ones. They stay put better if you can manage to pinch them while inserting them, then let them spring back open once they're in place.

I stopped biting my nails in mid-March and started using China Glaze's Calcium Gel Fortifier for my very weak and thin nails.

Products I use:

• China Glaze Calcium Gel Fortifier
  
  
• Burt's Bees Lemon Butter Cuticle Cream
  
  
• Sally Hansen Vitamin E Nail and Cuticle Oil
  
  
• Aveeno Active Naturals Intense Moisture Skin Relief Hand Cream (because I ran out of the really nice Sally Hansen stuff I've had forever and can't find it anymore)
  
  EDIT: It's a little hard to see unless you open the picture all the way up, but it's not just that the nails are longer, but that the skin around the nails and cuticles is much healthier. On Day 1 you can see flaking skin and spots where I had pulled the skin in runners toward the knuckle. Those are gone by day 28!

I bought this stuff, which has been pretty helpful so far. Problem is - and maybe it's because I don't know how to apply nail polish - the stuff gets on my food when I eat.

My son bites his nails down to nothing.

We’re trying some nail biting prevention polish with success for two weeks: https://www.amazon.com/gp/aw/d/B0012CD32W/ref=mp_s_a_1_9_a_it?ie=UTF8&qid=1550508097&sr=8-9&keywords=nail+biting+treatment+for+kids&dpPl=1&dpID=41Bpr4MJKCL&ref=plSrch

Adults also report success at self-application, so maybe it’s worth a try? It may not get to the root of the fixation but it may keep your fingers out of your mouth and that’s something.

Ooooh! Look what ya girl found (:

Hey man, ive been a nail biter for about probably 15+ years. decided to get rid of this nasty habit and bought some nail biting detergent polish. it honestly is so repulsive you will not want your hands near your mouth. ive almost kicked my habit but i need to constantly reapply it. i strongly recommend this for anyone battling this.

​

https://www.amazon.com/Mavala-Switzerland-Stop-biting-ounces/dp/B0000YUXI0

Yeah I understand. You can use something like this where you can buy a nail polish that helps you stop biting your nails. Though it is a bit expensive for some "nail polish" so look into something comparable.

https://www.amazon.com/Mavala-Stop-Biting-Sucking-0-3-Fluid/dp/B0000YUXI0/ref=sr_1_1_a_it?ie=UTF8&qid=1474316112&sr=8-1&keywords=stop+biting+nails&refinements=p_72%3A2661618011

there are a couple different ways to stop sucking your thumb. What I recommend is this clear "nail polish". It doesn't look like anything is on your nail and when you put it in your mouth it has a foul taste, discouraging the habit. Link: https://www.amazon.com/Mavala-Switzerland-Stop-Nail-Biting/dp/B0000YUXI0

In addition, it sounds like you have a fair amount of anxiety. Perhaps talking to your doctor about it may help.

-)

I just stopped biting a two or three weeks ago. I'm using Mavala Stop (literally the grossest thing I have ever tasted) and using Duri Rejuvacote to get them to grow faster... (not sure about the results yet :) Congrats to you! We're all gonna make it :)

That is a great idea! I used something called Mavala Stop which is a cheaper alternative I guess. It is ridiculously effective and under $15.

• Here's a link

There are a few products that could help:

I have bit my nails all my life and was finally able to stop 2 years ago (I'm 28 now) because of this stuff. It's just nasty. Keep putting it on and be consistent with it. Once they've grown out more there are lots of products you can use to help strengthen your nails.

If you're super desperate, I've heard good things about hypnosis.

I quit by applying a nasty, bitter, clear nail polish a few times a week. I grew up with the Thum brand, but it received poor reviews on Amazon. So here's something similar.

Or just check out what pinworms do.

Good luck!

Look for a color that you like, then turn the bottle over. If you can see the mixing balls inside, it's more sheer. If you can't see the balls, it's probably pretty opaque. Orly and Essie both have quite a few. In fact, Orly and Sally Hansen sell kits that are meant specifically for French manicures. For example, this one. I've never used one, but I'd say it's probably the kind of thing you want!

You can find it on Amazon: https://www.amazon.com/Mavala-Switzerland-Stop-biting-ounces/dp/B0000YUXI0/ref=sr_1_4_s_it?s=beauty&ie=UTF8&qid=1542292009&sr=1-4&keywords=mavala%2Bstop&dpID=41TVkUE41OL&preST=_SY300_QL70_&dpSrc=srch&th=1

It's from switzerland so not sure it shows up in stores like walgreens.

I agree with the other commenters, and think that seeing a psychologist would be an excellent idea. No five year old should have to live with that much stress, and finding a better way to help him let go of it is imperative.

In the meantime, there's a special type of bitter-tasting nail polish that can help him keep those fingers out of his mouth. I used to bite so much that my fingers would bleed and I'd end up with nasty infections. My parents used a product like the linked one (this was almost 30 years ago so I have no idea which brand), and I hated it with a fiery passion, but it sure as heck got me to stop biting.

I have a similar unconscious habit, and I need a strong and consistent reminder not to do it. Paint this stuff on the parts that you don't want to bite, and you will quickly learn not to bite there =;-)

Here are some links for the product in the above comment for different countries:

Use this next time and see if he still laughs

You might try hard as hoof it is a nail strengthening and cuticle conditioning cream.

I'm in a much better financial situation than I was 2 weeks ago!

I need some of this stuff

Use this on your fingernails, and carry these with you religiously... if you get a hangnail, or you've made a rough edge, clean it up with those instead of chewing. You can probably get both at your local grocery store or pharmacy.

Nail varnish may work, but as a guy I'm sure I'd get a few stares if I wore some. Although I've been thinking about this.

I've heard good things about this.

Mavala Stop worked for me, and another person I know. Good stuff.

No, it's completely clear.

Nice plant 👍🏼

It's clear and cheap and you just paint it on your nails. This will stop you from biting. The tough part is to then stop yourself from creating a new habit that is picking at your finger nails with your other finger nails lol.

I used to do that a lot when I was younger so my mum suggested that I use a special nail polish,that prevents you from biting your nails.It really worked as it was bitter like hell..if you forgot about it and were tempted to bite, you regretted the next moment.after 2 months or so the detering reflex grew so strong on me that I've never bitten my nails since.The brand is called Mavala,it's clear btw,no colour..

https://www.amazon.com/Mavala-Switzerland-Stop-Nail-Biting/dp/B0000YUXI0

1. Wear something close to your skin tone so it appears nude or choose a light pink.
   
   
2. If you need extra help breaking the habit I suggest this stuff: http://www.amazon.com/gp/aw/d/B0000YUXI0

I've heard this helps.

So sorry for the late response but what really helped me stop nail biting once and for all is to use the Mavala nail polish that is specifically designed to stop nail biting (you can get it on amazon: https://www.amazon.com/Mavala-Switzerland-Stop-Nail-Biting/dp/B0000YUXI0 or https://www.amazon.com/Mavala-Helps-Biting-Thumb-Sucking/dp/B00336WT3O). The taste is sooo bitter and disgusting that you don't want to put your finger back in your mouth. The only downside is that it can rub off onto finger foods or cooking, so if you eat chips or grab food with your nails you will taste the polish. But it's a small price to pay for long term reward. I cannot tell you how badly my nail biting was until I used this nail polish and now I have the longest nails out of all my friends. I hope you try it out some time! Good luck!

I used this: https://www.amazon.co.uk/dp/B0000YUXI0/

Took a couple of months, but it was worth it.

What if I told you that I have a solution that is on about ten bucks? http://www.amazon.com/Mavala-Stop-Biting-Sucking-0-3-Fluid/dp/B0000YUXI0

yea gloves is a little weird go the polish route then it should help and i'm sure your local pharmacy carries anti biting polish example

Get something like this. Pretty much makes your nails taste like shit.

I just started using this bitter nail polish. I didn't paint my entire nail since it's a bit shiny and I'm a guy.

So I dipped a toothpick into the polish and applied it just to the very edge of the nail and under the nail. The polish stays on for a long time and a small amount is all you need. This stuff is gross but is long lasting.

I also found that I bite my nails when I drive. So I bought driving gloves. I'm sure I look silly to others but I can't bite my nails with them on.

http://www.amazon.com/Mavala-Stop-Biting-Sucking-0-3-Fluid/dp/B0000YUXI0

There is nail polish that tastes horrid on Amazon. I've been using it and it coats your whole mouth with nastiness. I haven't bit my nails in a week.

https://www.amazon.com/Mavala-Switzerland-Stop-Nail-Biting/dp/B0000YUXI0

I love looking at my nails now.. they at least aren't a hot mess of blood and skin anymore!

I may not be the best at nail care but I have Trichotillomania and I bite my skin/pull hair and all that jazz. I used to bite my nails but used this:http://www.amazon.com/Mavala-Stop-Biting-Sucking-0-3-Fluid/dp/B0000YUXI0 when I was a teenager and even though I still pull hair/have other compulsions I don't ever bite my nails any more!

https://www.amazon.com/Mavala-Stop-Biting-Sucking-0-3-Fluid/dp/B0000YUXI0

Worth a shot.

Give Mavala Stop a shot. I've tried some of the other similar concepts and quickly grew used to the taste. This one is pretty awful and serves as a very fast reminder when I'm doing it unconsciously.

http://www.amazon.com/Mavala-Stop-Biting-Sucking-0-3-Fluid/dp/B0000YUXI0

Unfortunately, this also makes anything you touch with your fingers taste like shit. It's an unfortunate side effect, but I'll take it (my biggest problem is remembering to put the stuff on in the first place, once on it does a pretty good job).

I've bit my nails since I was a little kid. At the end of January my GF bought THIS from Amazon. Two applications was all it took, I haven't bit my nails since the first week of February.

http://www.amazon.com/Mavala-Stop-Biting-Sucking-0-3-Fluid/dp/B0000YUXI0 The quicker you can get her to stop the better.

First, maybe try painting your nails with this. It doesn't work for everyone, but it may help to provide a negative association with the biting. I find chewing on something else really helpful as well. Then head here: /r/CompulsiveSkinPicking, you may find something helpful.

I unfortunately already picked at my face (I have acne) and bit/chewed my hands long before the idea that I might have ADHD was even on my radar, and Adderall has not (yet) seemed to help. It is difficult to break, especially when you've been doing it since childhood (in my case). For me, a combination of harm reduction (always carrying bandages, alcohol pads, Neosporin in case I scratch myself - Hands are dirty even just washed) and redirection (instead, trim my nails, shave my face, do a face mask, put on expensive lotion) has been helpful.

And perhaps mention it to a psych. Could be other stuff going on.

Painted this on my nails for a few weeks. The hardest part was just convincing myself that I actually wanted to stop. I still miss it, but it's so nice not being embarrassed when my cuticles randomly start bleeding.

https://www.amazon.com/dp/B0012CD32W/ref=cm_sw_r_cp_apa_3E1GAbGB1J89F

I agree. We used this on our kid and he stopped. Available on [Amazon] (http://amzn.com/B0000YUXI0).

If you want to quit.

I bought the above for my boyfriend.. he's a nail-biter. Nearing the end of the first week and it seems to be working.

If you don't want to quit.. why not?

I use clear nail polish on my nails to put a physical barrier there. I don't like the plastic texture of it. I use this this when I know I'm going to be stressing out: https://www.amazon.com/Mavala-Switzerland-Stop-Nail-Biting/dp/B0000YUXI0/ref=sr_1_4_s_it?s=beauty&ie=UTF8&qid=1522717374&sr=1-4&keywords=mavala

It works really well during finals. It usually takes only one application to remind me not to bite. In addition, I file regularly (once or twice a week) to keep the edges from splintering. I also use a lot of cuticle oil to keep my cuticles from getting dry. At night, I use a really thick hydrating cream to make my hands smoother. It all keeps me from picking at everything.

This stuffs what you want

edit- Cleaned up the link

You need to come up with some kind of "competing behavior" for nail biting, generally something that you can't do it and bite your nails at the same time. There are products like this or you could put band-aids (preferably the fabric ones since the texture isn't pleasant to have in your mouth and gets your attention) around the tips of your fingers. Just something like that that you can do that is incompatible with nail biting until eventually the habit is broken.

paint your nails with bitterant

/uj seriously

We just tackled this like 2 weeks ago, and it only took 2 applications of this: mavala stop .

2.5 year old and was very attached to his thumb, so I was surprised at how quick it worked. He still hasn’t figured out how to settle down before naps/bed, so it takes a little more time to get him to sleep.

Try this, friend.

Yep most canned air is laced with denatonium benzoate:

http://en.wikipedia.org/wiki/Denatonium

Another thing you could try is acrylic nail polish that comes with denatonium designed to stop nail biting:

http://www.amazon.com/Mavala-Stop-Biting-Sucking-0-3-Fluid/dp/B0000YUXI0

Amazon Although I did see that says but to be used for children under 3, so its only an option if nothing else works until then...

There are biting deterrent aids that you can try. Here is one http://www.amazon.com/Mavala-Stop-Biting-Sucking-0-3-Fluid/dp/B0000YUXI0

Not exactly the right subreddit tho

http://www.amazon.com/Develop-10-Biting-Promotes-Growth/dp/B000Q0QRYC/ref=pd_sbs_bt_3

I was discussing how to cure nail biting in another new askreddit thread...

My nails get brittle sometimes or just end up flaking because of dish-washing. It takes a while to repair them but what I use is a Sally Hansen nail hardener, I take biotin supplements everyday, and should I notice my nails getting dry then I use either shea butter or rosebud salve.

Tons of people swear by that stuff ^

Nail biter of twenty years here, abruptly stopped after using this horrid stuff -- use it long enough and it will seriously curve your addiction. I have tried many others but this the real deal. Mostly odorless and invisible -- at first I was dowsing my finger with a heavy coat and it was a little glossy. I didn't make that mistake more than a couple times, this stuff is strong so it only requires a quick brush or you'll get a mouthful of bitter when eating any kind of finger food. Nail biters of reddit, if you have the slightest inkling of motivation to stop, buy this shit.

Clear polish that contains the most bitter substance known to man:

To be honest, once I started wearing nail polish I stopped because I was always afraid I'd chip the nail polish and that outweighed my desire to bite my nails, and also the nail polish got in my mouth which I hated. Not sure if that'll help you, though, so here are some articles that may help:

10 Steps to Quit Nail-biting

6 ways to stop biting your nails

Also, you may want to try a treatment that makes your nails taste bad. Like this one.

I'm a new dad with 5 month old twins so I haven't faced this issue yet. However I do know that a method to keep kids from sucking their thumb or nail bitting is to use a bittering agent on the thumb/nails. Mavala Stop is highly recommended on Amazon. You could use it to make the pacifier too bitter for her to want it in her mouth.

Well, it's hard to break an ingrained habit but you just have to stop. You can buy spicy/bitter nail polish that will help you avoid biting your nails.

http://www.amazon.com/Mavala-Stop-Biting-Sucking-0-3-Fluid/dp/B0000YUXI0

I have found no bite nail polish to help a ton. Mavala Switzerland Mavala Stop Nail Biting, 0.3 oz https://www.amazon.com/dp/B0000YUXI0/ref=cm_sw_r_cp_apa_foXWzbAX6YSN4

there's this nail polish that tastes really nasty thats supposed to help stop nail biting: http://www.amazon.com/Mavala-Stop-Biting-Sucking-0-3-Fluid/dp/B0000YUXI0

i hope this helps!

There is this clear coat you can use on your nails, here.

Personally, I have the same habit, only not as bad. I can stop myself as long as my nails aren't over a certain length. Once they get longer I can't seem to hold myself back, though, so I make sure my car, room, bathroom and kitchen have nail clippers so i can abate the urge.

Get this stuff and apply every other day. You will stop. Mavala Stop - Helps Cure Nail Biting and Thumb Sucking, 0.3-Fluid Ounce https://www.amazon.com/dp/B0000YUXI0/ref=cm_sw_r_cp_tai_uyGJxbXDMCB6B

Try covering the end of the pen with something edible but that tastes nasty. Used this one for my sister who wouldn't stop biting her nails - there was a special varnish you could put onto the nails - don't see why you can't put it on a pen?

edit: link

This nail polish is designed to stop people from biting their nails as it tastes really bitter. You can put a clear coat of this over the ends of cords, plugs for appliances.. basically anything you don't want your animals to chew. You may have to reapply a few times but eventually your cat will learn.

If you're serious about stopping and not you're not karma-whoring.

Used as a kid and stopped instantly.

http://www.amazon.com/Mavala-Stop-Biting-Sucking-0-3-Fluid/dp/B0000YUXI0

I am surprised no one has mentioned this. Mavela Stop is what worked for me. It tastes awful. Whenever you find yourself chewing on your fingers without thinking the awful taste of Mavela will stop you. After about a week you will notice a drastic improvement. Plus, it helped me form a habit of being cognizant of any time I put my fingers in my mouth.

You can buy anti fingernail biting polish that essentially puts a bitterant on your nails so you at least notice when you start biting them subconsciously. It pretty much makes your nails taste awful.

IIRC it takes about 2 weeks to break a habit, so just keep at it for a while and you should be golden.

Here's an example of the polish.

Two words. Malala Stop. https://www.amazon.com/Mavala-Stop-Biting-Sucking-0-3-Fluid/dp/B0000YUXI0

Me too. Buy some Mavala Stop on Amazon. It's absolutely wretched stuff. You can't get used to it and bite anyway. Does nothing for picking though. I don't know how I'll ever get over that... :(

Mavala Stop. You will stop putting your fingers near your mouth after about a week at the max.

I've been a nail-biter all my life. The awful tasting Mavala Stop (Amazon) has been the best solution for me. It tastes sooooo bad it forces me to not absentmindedly bite my nails.

I used Mavala Stop to end my 20 year nail biting frenzy. I had nails in 2 weeks. I could not eat gummy bears for about a month after because I was afraid of the flavor.

Friend of mine had a similar issue. She had a BIG nail biting problem. She fixed it with filing and some nail polish-like stuff that tasted downright NASTY, evidently.

I think this is it but I’ll send her a text

Hey I've just come across this post looking for stop-nailbiting subreddits. I've just gone through the 3 week mark of no biting having used a product called Mavala STOP! http://www.amazon.com/Mavala-Stop-Biting-Sucking-0-3-Fluid/dp/B0000YUXI0

I was bleeding a few weeks ago, now my nails are starting to get there :)

https://www.amazon.com/Mavala-Switzerland-Stop-biting-ounces/dp/B0000YUXI0/ref=mp_s_a_1_3?keywords=malva+stop&qid=1558558229&s=gateway&sprefix=malva&sr=8-3

I bought this one off of Amazon. It's a bit expensive, but it has helped me stop biting.

I don't bite my nails, but I do pick at them; I primarily bite my cuticles... and as someone who has had this compulsion her whole life, I implore you - please don't berate, get mad, or punish. These things are usually boredom-driven and anxiety/stress-driven. Getting angry will likely make this worse. It's not a conscious thing for most of us - for me and many others, you don't realize what you're doing until it's too late.
Anyway, here are the things my parents tried to do to stop me from biting that didn't work, but may work for you:

• No-bite nail polish such as this.
  
  
• Making her wear gloves.
  
  
• Putting hot sauce on fingers.
  
  I obviously don't really recommend any of this, because when they were done to me, it just made me more anxious... which, in the end, made the compulsion worse.
  
  You may want to try getting a kiddie manicure with her, or painting her nails yourself. Tell her how pretty her nails are when they’re painted, and make it fun for her. This could make her want to maintain them instead of bite them.
  
  I recommend coming over to /r/calmhands and /r/CompulsiveSkinPicking and read around, or ask all the questions you want; you will likely learn a lot about how to approach it, and how not to approach it.

they make anti- nail biting solution to put on your nails that tastes very bitter

My ex wife would bite her nails and complained that she couldnt' quit, so I got her some of this stuff. A few days later she was biting again and I asked if she was using the stuff and she said "no, that stuff tastes terrible".

I don't remember stopping, I just remember not doing it anymore, if that makes scene. My mom would just always tell me how dirty fingers and nails would get, just think of everything you touch. If that doesn't work there is always bitter nail polish.

You could try one of the bitter nail biting products e.g. this.

This stuff truly helped my fiancé because it really tastes awful.

As for me, I have acrylic/gel nails, which helped me stop not necessarily because they’re pretty and I don’t want to ruin them, I just literally can’t now.

this could be the answer to your problems. (and it's on sale!)

There's this clear nail polish that tastes like death. It's barely noticeable with no smell, so guys use it too, and whenever you go in for a bite you get this nasty, rancid, bitter flavor. After about two or three weeks, the habit is dropped.

http://www.amazon.com/Mavala-Stop-0-3-Fluid-Ounce/dp/B0000YUXI0
That might be the stuff, but I know there are other products out there you can try.

You can get very bitter tasting, transparent nail polish on Amazon.

Anyone suffering from this should give Mavala Stop a try.

I ordered this for myself, and I'm hoping it gets here today....I'm desperate.

Has anyone tried this before (or something similar)? I'm sick of my hands looking so jacked

That polish is legit the nastiest thing ever and you will 1000% think twice before putting your hand in your mouth. I mean even if they just freeze your lips momentarily that taste is stuck with you.

My bf didn't have the patience to keep telling me either so he sneaks and does this every couple of weeks or whenever he notices that I'm putting my hands in my mouth too much. It's the worst surprise the next day when you just wanna do something casual like... Lick your fingers after a delicious and messy taco but I 🤷🏽‍♀️ the man gets results.

Only had to use it once or twice. It's pretty gross to taste, but combined with carrying nail clippers it completely helped me stop.
