If managing the scaling associated with dandruff is stressing you out, get relief by using an anti=dandruff shampoo each time you wash your hair. One of the most effective medical ingredients is pyrithione zinc. This agent controls the fungus that thrives on the scalp and causes the bothersome flakes to form. Conditioners containing pyrithione zinc help to maximize dandruff control by exposing the scalp to an extra dose of the key ingredient. Unlike traditional conditioners, the product needs to be massaged into the scalp, then distributed evenly from hair root to tip. Clinical studies indicate that the use of a shampoo and conditioner with this active ingredient provides an improved anti-dandruff effect.
