When it comes to scalp health, few products are as widely recommended as ketoconazole shampoo. Originally developed as an antifungal treatment, this medicated shampoo has become a go-to solution for issues like dandruff, seborrheic dermatitis, fungal scalp infections, and even hair thinning in some cases.
In this article, we’ll explore everything you need to know about ketoconazole shampoo—how it works, its benefits, side effects, and the right way to use it.
What is Ketoconazole Shampoo?
Ketoconazole shampoo is a medicated shampoo containing ketoconazole, an antifungal agent. It works by stopping the growth of fungi that can cause scalp problems. Available in both prescription (2%) and over-the-counter (1%) strengths, it’s widely used for treating common scalp conditions.
Key Benefits of Ketoconazole Shampoo
1. Fights Dandruff and Flaking
Ketoconazole targets the yeast (Malassezia) often responsible for dandruff, reducing itchiness and white flakes.
2. Treats Seborrheic Dermatitis
This condition causes red, itchy, and flaky patches on the scalp. Regular use of ketoconazole shampoo can help control inflammation and scaling.
3. Helps with Fungal Infections
Scalp ringworm and other fungal infections respond well to ketoconazole’s antifungal properties.
4. May Support Hair Growth
Some studies suggest ketoconazole can block DHT (a hormone linked to hair loss), making it a potential supportive treatment for androgenic alopecia (male pattern baldness).
