Alopecia areata facts

Alopecia areata is a hair-loss condition which usually affects the scalp.

Alopecia areata typically causes one or more patches of hair loss.

Alopecia areata affects both genders.

An autoimmune disorder, in which the immune system attacks hair follicles, is believed to cause alopecia areata.

For most patients, the condition resolves without treatment within a year, but hair loss is sometimes permanent.

A number of treatments are known to aid in hair regrowth. Multiple treatments may be necessary, and none consistently works for all patients.

Many treatments are promoted which have not proven to be of benefit.
