I heard some doctor on the news recommend anything with zinc. Selsun Blue is what I use. Only use it whenever I have the problem, which is usually a few days out of every month. Works great, smells a bit strong, though. I think it's supposed to be better than H & S.
Pantene Pro-V has a new 2 in 1 shampoo with pyrithione zinc in it. I just started using it today as i only ever have dandruff in the winter, along with the rest of my dry skin. Winter is really a pain with all the moisturizing I have to do. I guess it's better than seeing dead skin on all of my dark furniture though.
