noun

Dandruff is a common scalp condition that results in the shedding of dead skin cells from the scalp. It is a type of seborrheic dermatitis that causes flaking, itching, and irritation of the scalp. Dandruff can be caused by a variety of factors, including overgrowth of yeast on the scalp, dry skin, oily skin, stress, and certain medical conditions. Although dandruff is not usually serious or harmful, it can be a persistent and bothersome problem for some people. Treatment options for dandruff include medicated shampoos, topical medications, and lifestyle changes, such as reducing stress and avoiding harsh hair products.
