What does zinc do for your scalp?

Zinc supports scalp health by fighting dandruff and oiliness with its antibacterial/antifungal properties, soothing itchiness by reducing inflammation (like from zinc pyrithione), regulating oil production for balance, and promoting strong hair growth by aiding cell division and keratin synthesis, preventing loss linked to deficiencies.
