Selenium Sulfide

Selenium sulfide is an antifungal agent commonly used in medicated shampoos and topical treatments. It works by slowing the growth of yeast on the skin and scalp, which helps to reduce flaking, itching, and irritation. It is primarily used to treat conditions like dandruff and seborrheic dermatitis.
