I have fine, long hair that has to be washed every day. I tend to avoid any shampoos that claim to either hydrate or volumize. Hydrating hair products tend to leave my hair flat and greasy looking. Volumizing hair products tend to leave my hair frizzy and fly-away. So I was hesitant to even try this product, but since it claimed to be "featherweight" I figured I would give it a shot since it was on sale. I bought both the shampoo and conditioner, and really was unimpressed the first time that I used it. I gave it a second try though, and really have enjoyed it ever since. It smells really great and leaves my hair smooth with out weighing it down - exactly what I want! I gave it 4 stars because I still prefer the Dove brand Heat Defense shampoo/conditioner, but since I like to rotate hair care products, this is now my new second favorite!
