Ketoconazole shampoo is an antifungal medicated shampoo commonly prescribed for scalp problems caused by fungal infection or yeast overgrowth, including dandruff. It belongs to a class of medications called antifungals and works by inhibiting the growth of yeast and fungi on the skin.
Unlike regular cosmetic shampoos, ketoconazole shampoo is formulated for a therapeutic effect. When scalp redness, itching, flaking, and irritation are linked to conditions that respond to ketoconazole, it can help reduce these symptoms.
What Is Ketoconazole Shampoo?
Ketoconazole shampoo is an antifungal medicated shampoo that is rubbed directly into the scalp and washed off after a few minutes. Ketoconazole 1% shampoo is used to treat dandruff, while ketoconazole 2% shampoo is used for dandruff, seborrheic dermatitis, and tinea versicolor.
It targets Malassezia — a yeast naturally found on the skin that can cause inflammation and flaking in people who are susceptible to it. This is part of why it’s associated with dandruff and seborrheic dermatitis. Unlike a regular anti-dandruff shampoo, ketoconazole shampoo contains an active medicinal ingredient specifically formulated to manage fungal growth.

Uses of Ketoconazole Shampoo
The exact use depends on concentration and the condition being treated.
1. Dandruff
- Persistent dandruff is one of the most common reasons for using this shampoo
- Can cause white or yellowish flakes, and an itchy, irritated scalp
- Helps eliminate the yeast responsible for dandruff and improve scalp condition
- More effective for stubborn or recurring dandruff than for one-time mild flaking
2. Seborrheic Dermatitis
- An inflammatory skin condition affecting oil-gland-rich areas like the scalp
- Symptoms: scaling, itching, redness, greasy-flaky patches
- Ketoconazole shampoo has shown significant efficacy in improving scalp seborrheic dermatitis symptoms with minimal side effects, although the shampoo form is FDA-approved for dandruff rather than specifically for seborrheic dermatitis.
3. Fungal Scalp Conditions
- May be used for certain fungal skin conditions
- Not all fungal scalp infections respond to shampoo alone
- See a doctor if you notice: significant hair loss, painful lesions, pus, swelling, or extensive inflammation — oral antifungal treatment may be needed
How Does It Work?
Ketoconazole works by inhibiting a fungal enzyme (cytochrome P450 14-alpha-demethylase) that fungi need to produce ergosterol, an essential component of the fungal cell membrane. This stops fungal growth and, at high enough concentrations, can kill fungal cells.
- If a scalp condition is related to Malassezia, reducing this yeast can ease scaling and irritation
- Not all dandruff is caused by fungus — dry skin, psoriasis, and contact dermatitis can also cause flaking, so persistent symptoms may need a proper diagnosis
