Tar 18 Medicated Shampoo is a clinically formulated treatment enriched with 1% Coal Tar to relieve symptoms of seborrheic dermatitis, psoriasis, and dandruff. It works by slowing excessive skin cell production—the root cause of flaking, itching, and redness. This extra-strength formula provides soothing relief from scalp irritation, helps reduce scaling, and supports long-term scalp health. Regular use of Tar 18 helps prevent recurrence, leaving the scalp clearer, calmer, and better balanced.
