Dandruff, or seborrheic dermatitis, is recognized as the most common disorder of the scalp. This condition can manifest as flaking, itchy skin, and inflammation on the scalp, affecting a significant portion of the population at varying intensities. It arises from a variety of factors, including excess oil production and sensitivity to a specific type of yeast that naturally resides on the skin.

Understanding the nature of dandruff is essential in cosmetology, as it not only influences client comfort but also impacts hair care practices and treatment options. Clients may seek treatments that help manage this condition, such as medicated shampoos, which are formulated to reduce flaking and soothe scalp irritation. On the other hand, while psoriasis, alopecia, and folliculitis are also scalp disorders, they are less prevalent compared to dandruff. Psoriasis can affect different areas of the body and can be chronic; alopecia generally refers to hair loss regardless of the cause and doesn't specifically relate to scalp health; and folliculitis, an infection of hair follicles, is less commonly experienced as a widespread scalp condition compared to the ubiquity of dandruff.
