How does this medication work? What will it do for me?
Coal tar shampoo belongs to the family of medications known as antipsoriatics and antiseborrheics. It is used to treat itchy, oily skin conditions of the head and scalp such as psoriasis, seborrheic dermatitis, and dandruff. Coal tar appears to have some anti-inflammatory properties, reducing itch and helps to remove scales that are associated with psoriasis. It may also slow down the growth of skin cells.
