Most of the female baldness can be self-healed, but there are also cases that cannot be self-healed, specifically related to the area of baldness, immune function, duration of baldness and other factors. Pemphigus belongs to non-scarring alopecia involved in immune mechanism, the mechanism of which is not yet completely clear and may be related to emotional stress, heredity, endocrine disorders, autoimmunity and other factors. Generally, the hair follicles of patients with patchy baldness will not be permanently damaged, and new hair can grow after the immune function is restored, which is related to the area of patchy baldness, immune function, duration and other factors. 1. Patchy baldness area: when the area of hair loss is relatively small, most of the patients will gradually heal themselves; if the hair loss is more serious, or even when all the hair is lost, the possibility of self-healing is smaller. 2. Immune function: If the patient can get rid of tension, anxiety and other bad emotions in time, and ensure enough sleep, avoid staying up late, and participate in appropriate physical exercise, it may help the immune system to return to normal, which will help the baldness to heal itself. 3. Duration of spot baldness: the longer the duration of spot baldness, the greater the chance that the hair follicles will be damaged, and it may also lead to scarring baldness, which is difficult to be cured by itself. Although spot baldness may be self-cured, it is recommended that patients with longer duration of the disease should go to regular hospitals for consultation, and adopt appropriate treatment programs under the guidance of doctors to promote the recovery of spot baldness, and do not blindly treat themselves.
