CAUSES :
Alopecia areata is not contagious.It occurs more frequently in people who have affected family members, suggesting that heredity may be a factor.
In addition, it is slightly more likely to occur in people who have relatives with autoimmune diseases.
The condition is thought to be an autoimmune disorder in which the body attacks its own hair follicles and suppresses or stops hair growth. There is evidence that T cell lymphocytes cluster around these follicles, causing inflammation and subsequent hair loss. An unknown environmental trigger such as emotional stress or a pathogen is thought to combine with hereditary factors to cause the condition.

Diagnosis :
First symptoms are small, soft, bald patches which can take just about any shape but are most usually round. It most often affects the scalp and beard but may occur on any hair-bearing part of the body.There may be different skin areas with hair loss and regrowth in the same body at the same time. It may also go into remission for a time, or permanently. The hair tends to fall out over a short period of time, with the loss commonly occurring more on one side of the scalp than the other.
