This medication is used to treat dandruff and other scalp conditions (such as itching, scaling, flaking). Salicylic acid and sulfur are known as keratolytic agents. This type of drug causes the skin to shed dead cells from its top layer by increasing the amount of moisture in the skin and dissolving the substance that makes the cells clump together. This effect makes it easier to shed the skin cells, softens the top layer of skin, and decreases scaling and dryness. Salicylic acid belongs to the same class of drugs as aspirin (salicylates).
