Nizoral Dandruff Shampoo is an over-the-counter therapeutic hair care treatment designed to treat and prevent dandruff. An overabundance of the Malassezia yeast is what causes dandruff.
Nizoral Dandruff Shampoo contains the antifungal medicine, Ketoconazole which prevents a substance called ergosterol from being made. Ergosterol is vital to the yeast cell membranes. Without ergosterol, holes will start to form in the membranes, and the cell contents will leak out.
Ketoconazole in Nizoral Dandruff shampoo will prevent excess Malassezia yeast from forming on your scalp and it will destroy the yeast that currently exists. In addition to treating the visible flaking related to dandruff, Nizoral Dandruff Shampoo will also treat the associated redness and itching.
Side effects related to the use of Nizoral Dandruff Shampoo are not common, but can include scalp itching, irritation, dryness, redness, burning, tenderness or blistering, inflamed hair follicles, hair loss, hair texture changes, rash, and greater tear production. If you encounter these side effects and find them quite bothersome, or if they do not diminish in time, see your doctor.
