Nizoral is the only over the counter dandruff shampoo with Ketoconazole - a clinically proven, powerful dandruff fighting ingredient.

Nizoral does more than just control dandruff symptoms - it works differently to get right to the root cause of dandruff by controlling the fungus that causes it.

Ketoconazole, the anti-fungal active ingredient in Nizoral® A-D, is 10X more effective at fighting fungus, the primary cause of dandruff, than the active ingredient in the leading dandruff shampoo brand.*

Nizoral is so powerful, you only have to use it twice a week. And, Nizoral® A-D has a clean, fresh scent that leaves your hair smelling great and is safe to use on color-treated, chemically processed and gray hair.

Nizoral relieves even stubborn dandruff based on clinical testing among people who suffered from dandruff for more than 10 years and who said they had tried different anti-dandruff shampoos in the past.
