Having tried a number over the years I can recommend T/Gel by Neutrogena,it certainly works for me.Another shampoo you can try but a bit more expensive is Nizoral.
I use T-Gel usually. Other brands I used in the past stopping getting stocked :-(
[i](Head & Shoulders stopped working for me in 1977, about the time they started adding scent to it and it no longer smelt chemical-like. No idea if it would work now.)[i]
