Alopecia Areata overview

Alopecia areata is a common autoimmune disorder that often results in unpredictable hair loss.

It affects roughly 6.8 million people in the United States and 147 million people worldwide.

In most cases, hair falls out in small patches around the size of a quarter. There may be only a few patches, but alopecia areata can affect wider areas of the scalp.

If there is a complete loss of hair on the scalp, doctors diagnose alopecia totalis. If there is hair loss throughout the entire body, the condition is called alopecia universalis.

Alopecia can affect anyone, regardless of age, gender, or race, though most cases develop before the age of 30.

In this article, we look at the causes and symptoms of alopecia areata, its diagnosis, and potential treatments.
