Ketoconazole shampoo is an antifungal solution to combat dandruff, itchiness, redness, and flaky patches caused by seborrheic dermatitis and tinea versicolor. It works by targeting the fungus Malassezia furfur, which is responsible for these scalp conditions. Regular use helps restore scalp health, reducing irritation and flaking for a cleaner, itch-free experience. For the best results, apply the shampoo as directed by your doctor, lather well, and leave it on for a few minutes before rinsing. Avoid using heavy oils before washing, as they may interfere with its effectiveness. Store it in a cool, dry place away from direct sunlight, and use it consistently to maintain a healthy, dandruff-free scalp.
