Ketoconazole shampoo is a medicated hair care product that is mainly used to do away with dandruff. It may also help to deal with an oily scalp and promote hair growth.

Ketoconazole is available over the counter in a 1% shampoo formula or by prescription in a 2% shampoo, foam, or cream. For over-the-counter options, Zeichner suggests Nizoral Anti-Dandruff Shampoo.
