Alopecia areata is a type of hair loss that typically affects the hair on the scalp. It occurs when the immune
system mistakenly attacks hair follicle roots, where hair growth begins.
It is most common in people younger than 20. But it can happen to children and adults of any age.
Medical treatments for alopecia areata may include medicines that
are either put on the scalp or injected. But because hair often grows back, treatment
may not be needed.
