I have very long hair (27+ in.) that gets super greasy near my scalp but super brittle and damaged beyond that. What I love about this product is that it's not greasy *at all* - my hair absorbs it right away in the shower and I barely have to wash out any excess. It combats chlorine damage like nothing I've ever seen, and my hair has become so silky that ponytail holders actually start slipping off! My only complaint is the strong scent. I'm not really a fan of the smell, and it's strong enough to set off my asthma if I'm not careful. But if you're looking for soft, shiny, full, tangle-free, and unbreakable hair -- not even salon brands can compete.
