Rated 5 out of 5 by from Gives good body Really helps plump up the hair when used before blow drying. Great for fine flat hair to give the illusion of thickness and body.

Rated 5 out of 5 by from love!!! It’s an all over the hair volume spray, feel like I applied dry shampoo spray without the white residue. I normally get 2 days out of my blowout, I get 4 days with this spray!! Spray from an arms distance, don’t go crazy, make sure your hair is damp enough before you use or it will give you a hard time blowing out & pull. If you know how to use it, it’s great!!!!
