It's time to eliminate dandruff completely – getting to the root of the problem. The cleansing shampoo soothes the scalp and keeps hair strong and resilient. That's why we developed the effective cleansing shampoo, with zinc pyrithione to fight the fungus that causes dandruff. As we deal with those pesky flakes, it also takes care of hair health. Massage into wet hair and scalp then rinse. Reapply and then leave for 2 minutes. Rinse well. Use twice weekly or as recommended.
