    Studysummary In this real-world study, JAK inhibitors like abrocitinib and tofacitinib led to substantial hair regrowth in 61% of alopecia areata patients over a median of 16 months, with 75% of non-responders achieving regrowth after switching medications; however, two serious adverse events were noted.
