Abstract

Abstract A clear, therapeutic hair care composition is presented having a low pH and useful in the local treatment of dandruff, seborrheic dermatitis and psoriasis of the scalp which resists oxidative decomposition. The shampoo is comprised of a detergent shampoo base, a therapeutic amount of a keratolytic agent and a keratolytic stabilizing agent to stabilize the keratolytic agent against oxidative decoloration decomposition catalyzed by ultraviolet radiation exposure. The keratolytic agent is preferably a salicylate and preferably salicylic acid and the keratolytic stabilizing agent is a tertiary amine.
