Alopecia areata (AA) is a form of hair loss driven by autoimmunity. To put it simply, alopecia areata occurs when our bodies mistakenly recognize our hair follicles as foreign invaders, and then begin to attack our hair follicles. This leads to the dysfunction of hair follicle stem cells, and eventually, hair loss. For more information, see these resources:
