This medication is used on the hair/scalp to treat dandruff and other scaly, itchy skin conditions (psoriasis or seborrheic dermatitis). Coal tar belongs to a class of drugs known as keratoplastics. It works by causing the skin to shed dead cells from its top layer and slow down the growth of skin cells. This effect decreases scaling and dryness. Coal tar can also decrease itchiness from these skin conditions.
