Selenium disulfide, also known as selenium sulfide, is a chemical compound and medication used to treat pityriasis versicolor, seborrhoeic dermatitis, and dandruff. It is applied to the affected area as a lotion or shampoo. Dandruff frequently returns if treatment is stopped.

Side effects include hair loss, irritation of the skin, weakness, and feeling tired. Use is not recommended in children less than 2–5 years old. Use in pregnancy or breastfeeding has not been studied. Selenium disulfide is an inorganic compound with the chemical formula SeS2.

Selenium disulfide was approved for medical use in the United States at least as early as 1951. It is on the World Health Organization's List of Essential Medicines. Selenium disulfide is available as a generic medication and over the counter. In the United States a month of treatment costs less than 25 USD. In the United Kingdom 100 ml of 2.5% shampoo costs the NHS about 1.96 pounds.
