Reddit mentions of Denorex Therapeutic Maximum Itch Relief, Dandruff Shampoo plus Conditioner, 10oz

Lol, tar is pretty much an end-all for bad dandruff. I use this. edit: It's like when you've tried using a lighter to light a fire, and instead you use a nuke.

It sounds like your dog has inhalant allergies. Symptomatic treatment is pretty much the only realistic option, unfortunately.

We had a little dog with terrible inhalant allergies for years. She was constantly itchy and we tried everything. Then one day our vet recommended we try this shampoo. We bathed her 4 times in two weeks and our mostly bald-pink dog turned white with new hair growth and almost completely stopped scratching. My wife called it "Miracle Grow." We bathed her once a week after that and was more or less symptom free for the rest of her life. When she passed away she was in full coat.

Unfortunately the shampoo is currently discontinued, but there are other shampoos out there with similar ingredients. Combining this one with this one would be a pretty close analog.

If you do try the medicated shampoo remember to let your dog soak in the lather for 10 minutes and then to rinse well. Bathing twice a week for a month should tell you if it will be beneficial--if there's no improvement in that time, then you could try a different shampoo.

Don't buy into the whole colloidal oatmeal or naturopathic route if you can help it. If shampooing helps, it's because your dog's skin condition is caused by, or exacerbated by the microbes living on your dog's skin, so you need a product with real anti-microbial ingredients.

So this is in the files of the group I admin on facebook, another admin wrote it up for us but hopefully it will help you:

Mites are a royal pain in the ass. Here is how I fought them:

1. Go to the vet. You need revolution for them as various mites are resistant to ivermectin. Cat dilution will be fine and go a long way. Excess medication should be stored in these to remain usable: https://www.amazon.com/gp/product/B00IP87H5U/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
   
   The hamsters need a drop on the back of the neck. I pull their scruff up and drop the medication onto what is between my fingers. Given what you guys are looking at, dose then once, then two weeks later, then three weeks later. Pregnant mums can be dosed, and the medication can be passed onto their pups. I wouldn't dose the pups until 4wks.
   
   
2. Toss everything wooden. Yes, it sucks. I'm so sorry. You can try bake/boil/freeze but in my experience this DOES NOT WORK. I'd have a good cry, then pitch it and remember you can always buy/make it again.
   
   
3. Clean everyone out. Use vinegar+water to clean everything. Be thorough. I would give everyone smaller cages if you can/have the means. Paper towel bedding, an igloo, water, food dish, and a wheel. That's it. They might be unhappy but they'll live. It’s a temporary accommodation.
   
   
4. Vacuum all your carpets. Throw out your vacuum filter, or wash it very well. If you have hardwood, vacuum it for now. We'll get to floors/furniture/etc later.
   
   
5. Hot wash/hot dry all your clothes, towels, bed sheets.
   
   
6. Buy permethrin (https://www.amazon.com/Sawyer-Products-SP649-Permethrin-Repellent/dp/B001ANQVZE/ref=sr_1_1?ie=UTF8&qid=1468184846&sr=8-1&keywords=permethrin). If you have cats, get rid of your cats. Dogs and other animals that are mobile around the house need to be removed from the house for a while. Open windows and doors and put fans on. Then permethrin the hell out of everything. Anything you cannot wash (floors, carpets, sofa, chairs, curtains, bed) needs to be permethrined. It smells like gasoline. If you get light headed, get outside. After ~24 hours it's safe to go back. If you can, move the hamsters outside too. They like your backyard, they can be stacked there.
   
   
7. After a week, clean everyone out. More paper towel. No bedding. Vinegar and water.
   
   
8. Minimize contact and handling. If you do handle, wash up to the elbows with anti-bacterial dawn soap.
   
   
9. There is an invermectin dose you can give yourselves to protect you from mites. (https://www.amazon.com/Denorex-Therapeutic-Maximum-Dandruff-Conditioner/dp/B00BR01AV0/ref=sr_1_2_a_it?ie=UTF8&qid=1468185361&sr=8-2&keywords=denorex) or (https://www.amazon.com/The-Healing-Tree-5060-Charcoal/dp/B008LUP5JC/ref=sr_1_10_s_it?s=beauty&ie=UTF8&qid=1468185373&sr=1-10&keywords=charcoal+soap) to alleviate itching.
   
   
10. Clean every week. Dose after two weeks. Then dose again after three weeks. Keep on the DL to followers for now, then use it as a teaching opportunity for everyone else. I wouldn't adopt out babies until you guys are certain you're mite free.
    
    
11. To find mites, they're easier on males - usually on the testes you can see them. Check and rifle through their balls and scrotum for bites. They also like to go under the arms.
    
    There’s also the tape trick. Wrap a bit of tape around your finger so the sticky side is facing outwards, then brush your hamster with it. Just be careful the tape is not too sticky (run it over your clothes to reduce stickiness if needed). Mites will usually come up as black specks.
    
    
12. YOU CAN DO IT! I believe in you.
