I have dandruff. Especially in front of my forehead it looks bad as it's in patches white flakes can be seen. I'm use to use selsun shampoo, but past a month i'm using biotique bio margosa anti dandruff shampoo and conditioner. It seems to worsen the dandruff. Could a good shampoo or treatment help getting rid of dandruff. Pls suggest .i have some boils too on my head like heat I guess.
