Alopecia totalis is the loss of all hair on the head and face. Its causes are unclear, but it is believed to be an autoimmune disorder. Research suggests there may be a genetic link: the presence of DRB1*0401 and DQB1*0301, both of which are human leukocyte antigens (HLA), have been found to be associated with long-standing alopecia totalis.
