We report the case of a girl presenting with patchy hair loss 1 week after a confirmed COVID-19 infection, who was subsequently diagnosed with alopecia areata (AA). Serum autoantibody testing returned negative results. Treatment involved external application of topical glucocorticoids and minoxidil to stimulate hair regrowth. After 6 months of therapy, a significant improvement in hair density was observed across the scalp, with only a single recalcitrant patch of AA remaining. Given the increasing prevalence of COVID-19, the potential for viral-induced AA warrants clinical attention.<\/jats:p>","DOI":"10.3389\/fped.2026.1723836","type":"journal-article","created":{"date-parts":[[2026,3,26]],"date-time":"2026-03-26T06:35:29Z","timestamp":1774506929000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Case
