Alopecia areata is an autoimmune condition that results in patches of hair loss. The immune system attacks the hair follicles resulting in baldness. Hair often regrows within 3 to 6 months. Sometimes, the hair that grows back in is white. Alopecia areata is just one type of autoimmune-mediated hair loss. Alopecia totalis results in full scalp baldness. Alopecia universalis results in complete hair loss over the entire scalp and body.
