Thanks for writing to us at Chat Doctor I will keep a possibility of Alopecia Area taAAAlopecia Area taAA 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 PVAMorales 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.
