Targeted Delivery of Zinc Pyrithi…e to Skin Epithelia.

Zinc pyrithione is an antifungal that works by targeting Malassezia yeast on your scalp—the main culprit behind dandruff and seborrheic dermatitis. It's effective at concentrations as low as 10-15 ppm and has been used safely in shampoos for decades because it balances real results with low toxicity risk.
