Ketoconazole shampoo is a medicated antifungal shampoo used to treat fungal infections of the skin and scalp. It contains ketoconazole (an azole antifungal) in a shampoo vehicle. Ketoconazole works by disrupting fungal cell membranes (it inhibits ergosterol synthesis in fungi). This shampoo is applied to the skin (typically the scalp) and left on for a few minutes before rinsing. It targets yeast/fungal organisms, so it is not used for bacterial or viral infections. (Common brand names include Nizoral® among others.)

Common uses of ketoconazole shampoo include:

• Seborrheic dermatitis (dandruff): A common scalp condition marked by flaking, redness and itching. It is often driven by an overgrowth of Malassezia yeast on the scalp. Ketoconazole shampoo helps clear the yeast and reduce inflammation, relieving scalp flaking and itch. (Even mild OTC-strength ketoconazole 1% shampoo – available without a prescription – is marketed for persistent dandruff.)
• Tinea (pityriasis) versicolor: A fungal skin infection (often on the trunk or shoulders) that causes discolored patches of skin. Ketoconazole 2% shampoo is FDA-approved for treating pityriasis versicolor by eliminating the Malassezia yeast on the skin. (Note: It may require repeated applications; pigment change may take time to normalize.)
• Tinea capitis (scalp ringworm): A fungal ringworm infection of the scalp (common in children). Ketoconazole shampoo is often used in combination with oral antifungals to help eradicate scalp ringworm. (It can also help reduce the contagious yeast load on the scalp.)
• Other fungal skin conditions: In practice, ketoconazole shampoo is sometimes used for other local yeast infections of the skin (for example in stubborn cases of scalp psoriasis with secondary yeast) because of its broad antifungal activity.

Ketoconazole shampoo is available by prescription in higher strength (2%) and often used under doctor supervision. A weaker 1% formulation (e.g. Nizoral A-D®) is available over-the-counter for treating dandruff. It is meant for external use only (avoid eyes and mouth) and should be used exactly as directed.
