Janus kinase inhibitors JAKis alopecia areata tofacitinib ruxolitinib baricitinib JAK inhibitors AA

TLDR Janus kinase inhibitors are effective and generally safe for treating hair loss in adults with alopecia areata.

The study reviewed literature from January 1, 2017, to April 16, 2023, on the efficacy and safety of Janus kinase inhibitors (JAKis) in treating adult patients with alopecia areata (AA). The findings indicate that oral JAKis, including tofacitinib, ruxolitinib, and baricitinib, are effective in reducing hair loss and are generally safe for use, even in severe cases of AA. The authors suggest that further research is needed to optimize dosage and treatment duration.
