Seborrheic alopecia, formerly known as early baldness, male pattern baldness, male alopecia, diffuse alopecia, and common alopecia, is related to heredity, androgen and seborrhea. The symptoms include excessive secretion of oil in the scalp and greasy hair. The clinical manifestations of patients with scalp fat excessive overflow, cause scalp greasy moist, mixed with dust and dander, a few days do not wash your hair is dirty, and stink, especially in the high temperature is so; sometimes accompanied by itchy scalp inflammation, is mainly due to the scalp moisture, bacterial reproduction infection caused by seborrheic dermatitis.
Guidance: the occurrence of androgenic alopecia is mainly related to genetic factors and androgens. The development of the disease is often accompanied by a normal level of androgens, and the genetic quality can increase the sensitivity of the hair follicle to androgens. The human hair follicle is a target organ sensitive to androgens, and its growth is periodic, usually through three stages of growth period, degenerative period and repose period. Secretion of human androgen is testosterone, testosterone into dihydrotestosterone in 5 alpha reductase under the action of androgen receptors and target cells in the scalp hair follicle and inhibits the growth of hair papilla, hair follicle cell growth and metabolism of interference, so that the hair in advance into the rest period, which caused the AGA.
Androgen is an important factor affecting the development of hair follicles. Androgen changes are closely related to the causes of seborrheic hair loss. The male body androgen after a reductase important transformation, combined with in hair follicle receptors, they can have complex reaction, the growth period of hair follicle shortening, hair follicle diameter becomes smaller; and the female body the most important androgen activity is very weak, and the amount of reductase is much lower than the male, a protective aromatase is in the scalp, so women should not suffer from the loss of hair.
