Alopecia areata is a disease that causes hair to fall out in small patches. It develops when the immune system attacks the hair follicles, resulting in hair loss. Sudden hair loss may occur on the scalp and other parts of the body. The condition rarely results in total hair loss, or alopecia universalis, but it can prevent hair from growing back. When hair does grow back, it’s possible for the hair to fall out again. The extent of hair loss and regrowth varies from person-to-person.
There’s currently no cure for alopecia areata. However, there are treatments that may help hair grow back more quickly and that can prevent future hair loss. There are also resources available to help people cope with the disease.
