What are the treatment methods for alopecia areata?

Alopecia areata, also known as circular hair loss or alopecia folliculitis, is an autoimmune disease primarily characterized by round or irregularly shaped areas of hair loss on the scalp or other body areas. Methods for treating alopecia areata include:

1. Topical treatments: These include corticosteroid creams or solutions applied directly to the affected area to suppress inflammatory responses and promote hair growth; and minoxidil solution, which stimulates the hair follicle growth cycle and promotes hair regrowth.

2. Oral medications: For severe cases of alopecia areata, glucocorticoid drugs such as prednisone acetate tablets or methylprednisolone tablets may be taken under medical supervision. However, potential side effects and the risk of recurrence should be carefully considered.

3. Topical agents: Such as minoxidil tincture or halometasone cream, which can stimulate scalp blood circulation and promote hair growth.

4. Phototherapy: Using ultraviolet B (UVB) or ultraviolet A (UVA) light irradiation in combination with photosensitizing agents can help reduce the immune system's attack on hair follicles and promote hair regrowth.

5. Hair transplantation surgery: Healthy hair follicle tissue is harvested and transplanted into the balding areas to increase hair density and improve the condition of hair loss.

As each patient's condition varies, treatment should be conducted under the guidance of a qualified physician.
