Hair Doctor     I’m very conscious of what I wear because of my dandruff problem. I’ve tried so many products but have been unsuccessful. Please help. You have to be careful that anti-dandruff products are not too harsh with their ingredients on the scalp, but a mild alternative is Sebastian Professional Remove Peeling shampoo with active ingredients of zinc pyrithion, piroctin, olamine and climbazol to prevent the reformation of dandruff and remove peeling which, with 4 weeks use on average, keeps your hair dandruff-free for up to 2 months.   I’ve heard a lot about permanent hair straightening. Does it damage your hair? We recommend Ionic Retexturising Treatment as it retains the water content while straightening, therefore avoiding damage to the hair.
