Targeted Delivery of Zinc Pyrithi…e to Skin Epithelia.

Zinc pyrithione (ZnPT) is an antifungal that works against dandruff and seborrheic dermatitis by targeting Malassezia yeast on the scalp. It's effective at very low concentrations (10-15 ppm) and works by dissolving into active form where the yeast actually lives—on the scalp surface and in hair follicles. The research confirms it balances real treatment results with safety when properly formulated.
