The causes of seborrheic alopecia are influenced by heredity, mental factors and diet. Heredity refers to patients with seborrheic alopecia at home, which is also related to anxiety, rest and excessive brain use. Dietary things, such as fried and spicy food, will promote sebum discharge, stimulate hair and skin to produce oil, and hair will fall off, so this is one of the reasons. There are also some reasons related to local overstimulation. Some people are prone to seborrheic alopecia when they wash their hair 2-3 times a day.

Patients are advised to start treatment as soon as possible after being found or diagnosed. The earlier the general treatment, the better the curative effect. The treatment of seborrheic alopecia is mostly comprehensive therapy, including oral, topical drugs and hair transplantation, which can achieve the best results. Conservative treatment with drugs is beneficial to improve the effect of hair transplantation and save effective hair follicle resources. The oral drugs suitable for female patients are mainly spironolactone and cyproterone, and the external drugs are selenium disulfide lotion, compound sulfur lotion and minoxidil. In addition, some patients can also choose other treatment methods, such as low-energy laser therapy and autologous platelet-rich plasma therapy, which can effectively improve the symptoms of hair loss in female patients.
