Alopecia areata é unha condición na que o teu sistema inmunitario ataca os folículos pilosos, o que provoca a perda temporal de cabelo sen deixar cicatrices. Pode aparecer como parches de perda de cabelo ou afectar a todo o coiro cabeludo ou o corpo, afectando a preto do 2% das persoas nalgún momento da súa vida. O principal culpable parece ser unha avaría na protección natural ao redor dos folículos pilosos.
Alopecia areata is an autoimmune disorder characterized by transient, non-scarring hair loss and preservation of the hair follicle. Hair loss can take many forms ranging from loss in well-defined patches to diffuse or total hair loss, which can affect all hair-bearing sites. Patchy alopecia areata affecting the scalp is the most common type. Alopecia areata affects nearly 2% of the general population at some point during their lifetime. A breakdown of immune privilege of the hair follicle is thought to be an important driver of alopecia areata.

Alopecia areata is an immune-mediated condition leading to non-scarring alopecia of the scalp and other hair-bearing areas of the body. It affects up to 2% of the global population. It can affect all ages, but the prevalence appears higher in children compared to adults (1.92%, 1.47%). A greater incidence has been reported in females than males, especially in patients with late-onset disease, defined as age greater than 50 years. Intralesional injection of corticosteroids has been reported to lead to better responses compared to topical steroids.
