welcome to hcm
thanks for the query
are you loosing scalp
since ANA is positive it appears to be Alopecia Areata
or lupus.It may take months and sometimes years to regrow all the hair.initially all these hairs will be grey or white.then after sometime original color will come back.can you please mention the titre for ANA level.ANA test results can be positive in people without any known autoimmune disease
. a false positive ANA result increases as people get older.
now cortisone injection
are available to stop in that area of hair loss.but you have to consult your dermatologist
