Nizoral Anti-Dandruff Shampoo is a medicated shampoo formulated with 1% ketoconazole that helps treat dandruff at the source. It works by targeting the fungus responsible for flaking and itching, helping to reduce visible flakes, soothe scalp irritation, and restore a healthier scalp with regular use.
What is Nizoral?
Nizoral is a medicated anti-dandruff shampoo that stands out because its active ingredient is Ketoconazole 1% (or 2% in some countries), an antifungal agent(Daily Med). Unlike standard shampoos that only wash away flakes, Nizoral targets the root cause of dandruff: a yeast-like fungus called Malassezia that lives on most scalps but can overgrow and cause irritation, flaking, and itching .
It is available over-the-counter (OTC) and is also used to treat the scalp condition seborrheic dermatitis.
