AB AT-A-GLANCEAlopecia  areata  is  a  nonscarring  hair  disorder.It  occurs  in  both  genders  equally  and  can  affect  every  age  group,  although  incidence  at  in  younger  age  groups  is  higher.It  is  the  most  common  form  of  hair  loss  in  children.  Clinically,  it  presents  with  well-demarcated  round  or  oval  bald  spots  on  the  scalp  or  other  parts  of  the  body.Of  patients  with  alopecia  areata,  5%  develop  hair  loss  of  their  entire  scalp  hair  (alopecia  areata  totalis)  and  1%  develop  alopecia  areata  universalis  (loss  of  total  body  hair).Nail  changes  include  pitting  or  sandpaper  nails.Alopecia  areata  is  thought  to  be  an  autoimmune  disease  with  a  possible  hereditary  component.In  general,  alopecia  areata  is  a  medically  friendly  condition,  but  it  can  coexist  with  other  autoimmune  disorders  such  as  Hashimoto  thyroiditis  and  vitiligo.
