This product was part of a hair protection kit I purchased from Birchbox. I used the spray heavily after washing/conditioning on damp, towel dried hair. I then brushed it through. My hair is thin and gets frizzy/curly when it's barely humid.
I felt like I had to use a lot to see results and my hair had to be pretty dry for it to absorb/coat my hair. My hair still showed signs of frizz and damage and got worse as the day progressed.
The spray absorbed well and didn't leave an unpleasant texture in your hair. It also smelled good. However, I can't imagine purchasing the full size bottle.
