Ketoconazole shampoo is a medicated antifungal shampoo used mainly to treat dandruff, seborrheic dermatitis, and some other fungal scalp conditions. It helps reduce itching, flaking, redness, and scalp irritation by lowering the yeast/fungus that can drive those symptoms.

What it does

  • Treats fungal overgrowth on the scalp. Ketoconazole targets the yeast commonly involved in dandruff and seborrheic dermatitis.
  • Reduces inflammation. That’s why it can calm an itchy, irritated scalp.
  • May help some hair-loss routines. Some sources note it may support hair health in certain cases, but that use is less established than its antifungal role.

Common uses

  • Dandruff.
  • Seborrheic dermatitis.
  • Some fungal scalp issues, including pityriasis versicolor in some guidance.

Quick note

It is usually used on the scalp, left on for a few minutes, then rinsed off. If you want, I can also tell you how often to use it and whether it helps with hair loss.
