Alopecia areata, also known as spot baldness, is a condition in which hair is lost from some or all areas of the body.[1] Often it results in a few bald spots on the scalp, each about the size of a coin.[2] Pain is not typically present.[2] Psychological stress may result.[2] People are generally otherwise healthy.[2]

Alopecia areata is believed to be an autoimmune disease.[1] Risk factors include a family history of the condition.[2] Among identical twins if one is affected the other has about a 50% change of also being affected.[2] The underlying mechanism involves failure by the body to recognize its own cells with subsequent immune mediated destruction of the hair follicle.[2]

There is no cures for the condition.[2] Efforts may be used to try speed hair regrowth such as cortisone injections.[1][2] Sunscreen, head coverings to protect from cold and sun, and glasses if the eyelashes are missing is recommended.[2] In some the hair regrows and the condition does not reoccur.[2] In others hair loss and regrowth occurs over years.[2] In a few all the hair on the scalp or all body hair is lost and loss can be permanent.[2][1]

About 2% of people are affected in the United States.[2] Onset is usually in childhood.[2] Males and females have the condition in equal numbers.[1] The condition does not affect a person's life expectancy.[2]
