Is treatment needed for alopecia areata?
I suddenly noticed several bald patches on my head, completely hairless. Although they don't hurt or itch, they greatly affect my appearance. I would like to know whether alopecia areata requires treatment.

Alopecia areata, also known as spot baldness, generally does not require treatment if the condition is mild. However, if symptoms appear or the condition is severe, treatment is usually necessary.
Alopecia areata is a common autoimmune disease primarily characterized by sudden hair loss, either locally or generally, resulting in round or irregularly shaped bald patches. If the area of hair loss is small and the patient experiences no significant psychological distress, observation for a period of time may be appropriate, as some patients with mild cases may experience spontaneous recovery.
If regional hair loss has already occurred, accompanied by redness and swelling of the hair follicles, or even the formation of small pustules, this indicates a more severe condition. At this stage, treatment is generally required. Treatment options include topical corticosteroid therapy, phototherapy, and oral medications, all aimed at suppressing abnormal immune responses and promoting hair regrowth.
Alopecia areata not only affects physical appearance but may also cause psychological stress and social difficulties for the patient. Therefore, in addition to physiological treatment, psychological counseling and support are also essential components of the treatment plan.
Treatment for alopecia areata should be determined based on the individual case to achieve the best therapeutic outcome.
