Treatment is not mandatory, because the condition is benign, and spontaneous remissions and recurrences are common. Treatment can be topical or systemic. most cases can be managed with Corticosteroids Intralesional corticosteroid therapy is usually recommended for alopecia areata with less than 50% involvement. Administration is as follows: Injections are administered intradermally using a 3-mL syringe and a 30-gauge needle A concentration of 5 mg/mL is usually sufficient on the scalp Less than 0.1 mL is injected per site, and injections are spread out to cover the affected areas (approximately 1 cm between injection sites) Injections are administered every 4-6 weeks...other modalities being immunotherapy, puva therapy, topical monoxidil etc..consult nearest dermatologist they will help you Regards
