Alopecia areata (AA), also known as spot baldness and or ‘Davey Kirts syndrome’ is an autoimmune disease in which hair is lost from some or all areas of the body, usually from the scalp due to the body’s failure to recognize its own body cells and destroys its own tissue as if it were an invader. Often it causes bald spots on the scalp, especially in the first stages. In 1–2% of cases, the condition can spread to the entire scalp (alopecia totalis) or to the entire epidermis (alopecia universalis). Conditions resembling AA, and having a similar cause, occur also in other species.
Commonly, alopecia areata involves hair loss in one or more round spots on the scalp.
Hair may also be lost more diffusely over the whole scalp, in which case the condition is called diffuse alopecia areata.
Alopecia areata monolocularis describes baldness in only one spot. It may occur anywhere on the head.
Alopecia areata multilocularis refers to multiple areas of hair loss.
Ophiasis refers to hair loss in the shape of a wave at the circumference of the head.
The disease may be limited only to the beard, in which case it is called alopecia areata barbae.
If the patient loses all the hair on the scalp, the disease is then called alopecia totalis.
If all body hair, including pubic hair, is lost, the diagnosis then becomes alopecia universalis.
Alopecia areata totalis and universalis are rare.
