Nizoral Dandruff Shampoo Review in Shampoo at Review Centre Arcolane&Brand Shampoo + Conditioner 2% - 60ml ( Ketoconazole ) ( Galderm...I have tried many dandruff shampoos over the years and not found one to help. In fact, many made the problem worse. Maybe it's because my dandruff problem comes from an itchy scalp and dry skin. Nizoral actually works ! It doesn't solve the problem but there is a definite improvement. They've obviously done their research.
