In women, the hair is sparse and dry, and the hair is slowly and scattered shedding, exposing the scalp, but rarely formed. The possibility of balding.
Mental alopecia is hair loss caused by excessive mental stress. Excessive mental stress causes the scalp hair muscles to contract, and the capillaries that transport nutrients to the hair follicles contract, causing local blood circulation disorders, resulting in hair ecological changes and malnutrition.
