Introduction
Itching accompanied by hair loss is primarily caused by seborrheic dermatitis and seborrheic alopecia. These conditions are commonly observed in young to middle-aged men, largely due to elevated androgen levels. Androgens stimulate sebaceous gland proliferation and secretion, resulting in excessive sebum production on the scalp. This sebum travels along the hair follicles and sebaceous ducts to reach the skin and scalp surface. Malassezia (formerly Pityrosporum) fungi—normal skin commensals—are frequently implicated. Patients often have a family history of these conditions; therefore, maintaining a regular lifestyle is recommended.
