Pyrithione Zinc 1% (Active)
Flagged in 2
Scout's take
OTC anti-dandruff active. Genuinely effective against Malassezia yeast (the cause of seborrheic dermatitis and most dandruff), but EU restricted in cosmetics as of March 2022 except narrow OTC anti-dandruff use due to rat developmental and reproductive toxicity data. EWG 7-8.
