Missing Volumizing Ingredients

On a scale of 1-10 on giving my blonde, fine hair volume, I give it a two. I applied this to towel dried hair with my other products and blew it dry. Then I tried it with my hair 90% blown dry and styled using it, which was slightly better. I also tried it as a refresh with day after hair, still the same results. This product doesn't leave hair sticky or heavy but it's probably why it doesn't work. There are too many other volumizing sprays that work better; Eleven, Kevin Murphy and Keune.

It works better than others I’ve tried

Definitely gave my hair some lift. I’m going to keep working with it and see if I can get more.
