Dermatar Extra Strength Therapeutic Shampoo is formulated with a powerful combination of coal tar and salicylic acid. Coal tar is categorized as a keratoplastic agent, effectively prompting the shedding of dead skin cells from the skin's surface and slowing down the growth of new skin cells. This action significantly reduces scaling, dryness, and alleviates itching associated with skin conditions. Salicylic acid, on the other hand, is a key player in dandruff care. It helps in clearing your scalp of dry skin and dandruff, resulting in reduced itching and irritation.
