Dandruff shampoo is a specialized hair care product designed to reduce or eliminate dandruff, a common scalp condition characterized by flaking and itching. These shampoos often contain active ingredients like zinc pyrithione, ketoconazole, or salicylic acid, which help to control the growth of fungus and reduce inflammation on the scalp. Using dandruff shampoo regularly can help maintain a healthy scalp and minimize the appearance of flakes. It is typically recommended to massage the shampoo into the scalp and leave it on for a few minutes before rinsing. Consistent use can lead to improved scalp health and comfort.
