Seborrheic dermatitis is a chronic, pustular, scaly superficial inflammatory skin disease that occurs at sites of sebum overflow. It can be accompanied by varying degrees of itching. The exact cause of the disease is not completely clear, but it is generally believed to be related to an increase in sebum secretion or changes in its chemical composition. Additionally, colonization and infection with Malassezia are also somewhat related. Other factors such as mental state, diet, alcohol consumption, deficiency of B vitamins, infections, and fatigue can also influence the occurrence and development of the disease to varying degrees. Clinically, seborrheic dermatitis is a challenging condition, generally managed symptomatically. Although it can be clinically cured, it is a chronic condition that may still recur.
