This shampoo works well for controlling most of my frizz and fly-aways on hot humid days. I have very fine, wavy hair that is hard to control in the summer time. This shampoo helped fend off frizz for most of the day, but not completely. Though, I haven't come across a product that can yet. The shampoo smells good and I'd recommend it to anyone if they are looking to try something new to fight frizz.
