Ketoconazole zinc pyrithrin shampoo is primarily used to treat fungal infections of the scalp, particularly *seborrheic dermatitis*, which causes an itchy rash with dry, flaky scales . It’s also effective in controlling *dandruff*, by reducing the growth of fungi that contribute to these conditions.

The shampoo works by combining two antifungal agents: ketoconazole and zinc pyrithione. Ketoconazole destroys the fungal cell membrane, while zinc pyrithione helps slow down the growth of fungi on the scalp
