The one I found that works the best is Prell.. I get extremely oily hair and it works wonders!! Especially when I was a kid, I could wash my hair in the morning before school and by the time it's dry it would be like I haven't washed my hair in days!! Finally my mom bought me Prell and told me to try it...It worked wonders! I still use it every couple weeks for my hair.
Shampoo specified for oily hair, nothing heavy, light rinse conditioner if ya need it or some light spray in...watch how much product ya use in your hair also. I like Dove for drug store product and Neutrogena.
