Sebastian Dark Oil Lightweight Shampoo

I like this shampoo. I've been searching for something to not make my hair greasy quick. I have a ton of hair but it's fine and gets greasy within a day of washing. I don't see anything miraculous about this shampoo in alleviating that problem I still get about the same results like other professional shampoos. It's just my hair and water I guess. The smell is great though and doesn't smell like a strong old lady or something unpleasant. So I can at least say that's it's good quality. Maybe it's more affective on someone with thinner hair. I would still buy again because it's decent.
