alopecia areata. this is an autoimmune condition due to the attack of lymphocytes​ against hair roots. It results in the formation of bald patches on the scalp. It can affect other  a hairy areas of the body also like eyebrows and  beard. It has to be treated properly for long duration until the immunity comes down. Once the immunity is controlled, hair grows back over the patches. Apart from what you are taking, other therapies which work are phototherapy.  Please contact me with photos through online consult option for diagnosis and treatment.
