Nizoral Original Ketoconazole 2% Anti-Dandruff Shampoo is a clinically proven medical-grade treatment specifically formulated to address the root cause of dandruff rather than just rinsing away flakes. Utilizing 2% Ketoconazole, it targets Malassezia fungus to provide rapid relief from scalp itching, scaling, and inflammation. Ideal for those with persistent seborrheic dermatitis, this fragrance-free formula restores scalp health while remaining gentle enough for color-treated hair.
