I received a sample for testing purposes, but all opinions are my own. I have naturally wavy, frizzy hair with highlights. Usually, my waves are pretty undefined and dry. This spray seemed to give my hair (and ends especially) exactly the right amount of protein that they needed to look healthy and smooth. It was easy to spray in and comb through my hair, and didn't have a significant fragrance. I let my hair air dry, and was happy with how it turned out; this spray also works as a heat protectant, but I rarely use hot tools. Overall, I felt that this was a super easy way to improve the look and health of my waves!
