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.
