As you know, alopecia areata
is considered an autoimmune disorder and people with this condition also tend to get other disorders such as pernicoius anaemia or vitiligo
(white patches, i.e., loss of normal skin colour).
Tests for autoimmune diseases should be done as part of management such as ANA, parietal cell antibodies
, Vit b12 levels, complete hemogram, LFTs.
There are several treatment options, although no cure exists.
Options include: intralesional steroid injection; topical steroids; minoxidil
2% (use and leave overnight); or old fashioned options such as camouflaging hair loss with hair pieces or styling products if medications do not help.
