This medication is used to treat a certain skin condition (seborrheic dermatitis). In this condition, it is believed that a fungus (Malassezia furfur) infects the skin, resulting in dry, flaky skin (scaling) on the scalp, face, ears, chest, or upper back. Ketoconazole is an azole antifungal drug that works by stopping the growth of fungus.
How to use Extina Top

If the can is warm or the foam is runny, place the can under cool running water for a few minutes before using.
