Reddit mentions of Kerastase Resistance Volumactive Mousse, 5.1 Ounce

Sweet! OK, here goes. I think hold/volume go hand-in-hand to an extent, but I'll try to separate by my favorites. Adding some sort of texturizer is CRITICAL for me to give my hair enough grip to hold curls and volume (I have slippery-straight hair, as I assume you do. Mine's pretty fine but there's a lot of it.) Also note that I choose between big hair and soft hair sometimes. At its biggest, not a chance will I run my hands through it without getting snagged.

Volume

• Oribe Dry Texturizing Spray: A spray directly at the roots is magic. Instant root lift in a can. Also works as a bit of a dry shampoo. (Bumble and bumble Dryspun Finish is similar but runs out SUPER fast.)
  
  
• L'Oreal Professionnel True Grip: Tiny tube; not cheap for the size. It does last a long time, though. It's a powder you shake at the roots and fluff up. Instant volume. Shaken through all hair will give more grip for hold. (Other similar options: Bumble and bumble Pret-a-powder is less grippy but smells good; I hear Schwarzkopf Dust It is good)
  
  
• Kerastase Volumactive Mousse: A little goes a long way with this stuff. This one's very good if you're going to blow-dry, as you apply on wet hair. (Similar products: Big Sexy Hair Root Pump Plus, but it's not as dense and smells kind of weird; Bumble and bumble Full Form Mousse is wonderful but is easy to go through quickly)
  
  Texture
  
  All the ones above will add texture. For allover texture, though, I'd put in something after you shampoo. I'm still experimenting to find my HG. I've been using samples of Bumble and bumble Styling creme (not the lotion-spray) with a dab of Brilliantine to keep shine. My hair stays way longer with this. Sometimes I also use the B&b Thickening spray, because I've had samples on hand. Also, Bumble and bumble Texture used VERY sparingly will give me a root boost. Too much and you'll look like a greaseball in minutes!
  
  Hot Tools
  
  
• BioIonic 1" iron with rotating barrel: Tricky to use at first, but once you get it it's great. Does not pull on your ends or leave creases, but has a clip. Mine's the Drybar yellow one, but is identical to this except for its steep price tag. I also have a Sedu curling wand but I burn myself and cri evrytym.
  
  Hold
  
  
• Sebastian Shaper/Shaper+: My hairdresser uses this. They just changed their packaging so I've found it pretty cheap on Amazon and at TJ Maxx (~$7). When I heat-style my hair, it's great to spray all over (sometimes too much), let your hair cool and the spray dry, then brush out. You won't lose whatever you've done with this stuff. Lasts all day. (Similarly good: Big Sexy Hair Spray & Play is less brushable; Bumble and bumble Classic leaves your hair softer but does not hold as well.
  
  Shampoo
  
  
• Bumble and bumble Surf shampoo and conditioner: FINALLY! Does not weigh my hair down, but does not dry it out. I'm on set No. 3 and don't know if I'll ever change.
  
  Products that do not work for me
  
  I've wasted lots of money.
  
  
• Bumble and bumble Surf Spray: Smells divine; gives marginal volume. Will not do anything to make my hair less straight or, in a few hours, less flat.
  
  
• Living Proof Thickening Creme/Mousse: Oh my goodness these smell good. They both makes your hair feel good but no thicker than without it.
  
  
• John Frieda Luxurious Volume Anytime Volume Refresher: Just meh. It's fine, but doesn't do enough for my Big Texas Hair dreams.
  
  
• Sally Hershberger Supreme Lift: Nothing to write home about.
  
  
• Oscar Blandi Lacca Hairspray: STICKY! Holds well, but not good for me.
  
  
• TIGI Catwalk Your Highness Root Boost: Too liquidy so it goes on too heavily and weighs hair down. Needs a rework on the nozzle.
  
  TL;DR All I want is enormous hair with body for days. One day I'll figure it out.
