Alopecia Areata (or AA) is a common type of hair loss affecting both men and women of all ages. It usually starts as sudden small round patches of hair loss, that occurs singly or in multiple areas. There is no pain or itch associated with the hair loss, and a person may not be aware of it until someone else notices it. AA happens because the body's immune system mistakenly attacks the hair follicles. However, the follicles retain their ability to regrow hair, and the hair loss is not permanent in most cases.
While AA does not cause physical pain the psychosocial effects of hair loss can be significant. In addition, there are other autoimmune conditions like vitiligo (a disorder that causes patchy whitening of the skin) that is associated with it.
Patients notice coin-shaped patches of hair loss in hair-bearing areas, but it is most noticeable on the scalp. Some lose a few bald spots that regrow hair in a few months. In others, extensive patches occur. In a few people all the hair is lost (known as alopecia totalis and alopecia universalis) and may be permanent.
Small bald patches on your scalp or other parts of your body.Patches may get larger and grow together into a bald spot.
Hair grows back in one spot and falls out in another. You may lose a lot of hair over a short time.
Fingernails and toenails become red, brittle, and pitted.
Not all people with alopecia areata require treatment; many patients with limited disease will experience spontaneous hair regrowth. For patients who use treatments, there are several options available and the suitability depends on the site and severity.
