What is the cause of alopecia areata?

• The cause of alopecia areata remains unknown.
• An immune mechanism is postulated in which auto- antibodies are produced against the hair follicles and this results in premature shedding of the hair.

Treatment:

• Consult your doctor.
• There is no reliable treatment for alopecia areata since spontaneous regrowth occurs in most patients. Many forms of therapy including intralesional or topical steroids, anthralin or contact sensitisation have demonstrated short term hair regrowth, but they do not alter the long term course of alopecia areata.
• In complete hair loss, wearing a wig may be helpful.
