    TLDR Low-dose intralesional corticosteroid treatment led to rapid hair regrowth in localized alopecia areata.
    A 32-year-old Chinese woman with localized alopecia areata (AA) experienced rapid hair regrowth following treatment with intralesional triamcinolone acetonide (ILTA) at a concentration of 5 mg/mL. The treatment involved multiple 0.1 mL intradermal injections spaced 1 cm apart. After 3 weeks, the patient's hair regrowth was significant, with her Severity of Alopecia Tool (SALT) score improving from 21% to 3–4%. The patient reported high satisfaction with the treatment, which was well-tolerated. This case underscores the effectiveness and tolerability of ILTA for managing localized AA.
