Redken Thermal Spray 22 High Hold - Thermal Heat Protectant and Setting Mist, For Curling and Flat Irons, Lasting Frizz Control & Protects Against Heat Damage

Seems to work great. It does leave a residue that can lead to dull hair, but use sparingly with a lower temp to avoid this.

I have thick wavy hair. To get it straightened I apply this before styling. When I use it on damp hair, it’s a softer finished touch. When I use it on dry hair and then straighten it, it’s a bit more stiff but the style lasts longer. Scent is mild, can create volume, last long for the price. Will buy again.

I have super fine hair and this works great when using any heat. It can be a little crunchy but brushes right out. Has a subtle smell but I like it

READ DIRECTIONS: THIS IS FOR CURLING ONLY!! DO NOT USE THIS HEAT PROTECTANT TO GIVE YOURSELF A STRAIGHT OR BLOWOUT STYLE!!!! This has SUPER, INTENSE hold. I only use it PRIOR to curling my hair and only use it a section at a time because it is sticky and has a VERY STRONG HOLD. It works best before air-styling my hair and using the coanda curling attachment on my Shark Glam. It does a great job at protecting my hair and keeping the curl. I spray it, brush it, curl it, and then I pin the curl up. After I'm done, then I take the pins out after it has set and run my fingers through it. You won't be able to brush your hair due to the hold, but if holding a curl and longevity is what you are after, this is for you. It also SMELLS AMAZING!! I want a perfume that smells this good!

Let me start by saying that products that perform miracles on everyone else's hair never seem to work for me. It could be my hair: super-fine, but a lot of it (at least until menopause & COVID); some natural curl, more frizz actually. But this could be a holy grail for me. I use this on dry hair before styling with a curling iron. It does make my hair a little crunchy, but I actually need that for my hair to hold a curl, if that makes sense. The crunchiness eventually goes away, but the curl and volume last. There is no product buildup to weigh down my hair. I had to take away one star for the smell. Oh the smell!!! Reminds me of wet dog and lasts until I wash it out. I'm hoping that it was just my bottle, and maybe the next one won't smell as bad. If you have impossible hair like me, you might want to give it a try.
