A medicated dandruff shampoo is a specially formulated shampoo designed to manage the underlying causes of dandruff, rather than just washing away flakes.

These ingredients of antifungal shampoo for scalp regulate Malassezia fungus, decrease scalp inflammation, and reduce chronic flaking and itching.

  • The poor quality of the product or not taking good care of the scalp

It is important to understand what type of Dandruff you have (dry, oily, or medical) to determine what solution may help.
