Is Zinc Pyrithione considered effective in treating the symptoms of seborrheic dermatitis, and dandruff?
I will be concise here as the issue is explored at length in the article on pyrithione zinc.
“Shampoos containing zinc pyrithione (PZ) have been shown in many double-blind studies to be effective in controlling the clinically evident scaling in dandruff.”
