I have to say I disagree with the other reviews. I don't find this product has any significant effect on my curly/wavy and slightly frizzy hair ... the only thing it really did was weight my hair down. I like other Sunsilk products, but this one ... not a fan.

I love this product too. I got a sample of this in the mail and I tried it a few days ago. I have fine straight hair but I wanted to try it out anyway. It kept my hair smooth and straight all day without any additional sprays/creams..it also kept my hair frizz free on a hot humid day.

I plan to buy the full bottle of this pretty soon.

This leave in treatment battles the frizz of non-straight hair. If your hair is wavy or curly, this will define those waves/curls and leave your hair feeling very soft. I also LOVE the smell of this product. This product claims to be a combination of a conditioner and a gel. I agree with those claims. My hair looked, felt and smelt amazing after using it.
