Zinc Pyrithione

Zinc pyrithione is a coordination complex of zinc with antifungal and antibacterial properties. It is widely used as an over-the-counter treatment for dandruff and seborrheic dermatitis. It works by inhibiting the growth of yeast (Malassezia) on the scalp, which is a primary contributor to dandruff.
