Hello. Thanks for writing to us at Chat Doctor I will keep a possibility of Alopecia Area ta(AA)Alopecia Area ta(AA) has an autoimmune etiology. It presents as smooth bald patches of hair loss, most commonly over the scalp but the patches can also present on the beard, mustache or eyebrows or eyelashes. The patches of Alopecia Area ta are smooth, and there is no evidence of inflammation like scaling or erythema or itching. People often seek treatment because the bald patches are unsightly and are easily noticeable to others. Various treatment options in alopecia errata in order of the choice of treatment are:-Intra-lesional Triamcinolone acetone: This is first line treatment in adults followed by other modalities like:-Topical Potent steroids (Mometasone Furnace, Clobetasol propionate)-Topical Minoxidil solution-Topical Anthranalin-Topical PVA(Morales +UVA therapy). All of them are effective but intra-lesional steroids are the most accepted line of treatment and is a reproducible effective therapy for focal type of alopecia errata. It can be repeated after 3 -4 weeks and usually hair regrow after 2 injections, given 3 weeks apart. A dermatologist would usually administer this treatment in his office. The injection has to be placed into the patch of hair loss. I would suggest that you visit a dermatologist in your region for the needful. Regards
