Trying to make sense of anti-dandruff shampoos? Those with selenium sulfide or zinc pyrithione inhibit yeasts from growing and tar shampoos slow the growth of cells on the scalp. Salicylic acid and sulfur loosen the flakes, making it easier to wash them away. Studies have shown that anti-fungal agents, such as pyrithione zinc, can kill some of the yeasts and slow the rate of skin cell turnover. In severe cases, prescription strength preparations may be required. If you don’t see any improvement after using an anti-dandruff shampoo for several weeks or you notice redness and/or bumps on your scalp, see your doctor to determine the underlying cause. New advances in the form of anti-dandruff conditioners can also add an extra boost of the active ingredient on your scalp to further reduce irritation and flaking, as well as improve manageability. Enhanced anti-dandruff effects can be achieved if the same medical ingredient is contained in both the shampoo and conditioner.
