Seborrheic dermatitis is a chronic inflammatory skin disease that occurs more frequently on the scalp because the scalp is an area with a dense distribution of sebaceous glands. It is currently believed that seborrheic dermatitis of the scalp is more frequent in men than in women, and that the disease occurs mostly in young adults, mostly between the ages of 30 and 60. The occurrence of seborrheic dermatitis is associated with an overly oily diet, as well as improper treatment and medication in some people, such as long-term use of glucocorticoids, and possibly genetic and metabolic disorders. When treating seborrheic dermatitis, the patient must control smoking and alcohol consumption, seborrheic dermatitis can also be treated with topical tetracycline, as well as vitamin supplements, such as vitamin B6, B2, B1 of the B vitamin group, and short-term application of corticosteroids if seborrheic dermatitis has occurred with local oozing and exudation.
