Alopecia areata is a common autoimmune condition that causes sporadic hair loss. In the United States, it affects around 6.8 million people.
Hair falls out in little patches about the size of a quarter in the majority of cases. For the most part, hair loss is limited to a few spots, however, it can be more severe in certain circumstances. It can sometimes result in total hair loss on the scalp (alopecia totalis) or, in severe cases, the entire body (alopecia Universalis).
Anyone, regardless of age or gender, can be affected, albeit the majority of instances occur before the age of 30. The causes and symptoms of alopecia areata, as well as its diagnosis and treatment options, are discussed in this article.
Alopecia areata is an autoimmune condition that causes common hair loss. There is presently no cure for alopecia areata, although doctors can recommend treatments to help hair regrow more quickly.
