Complete Regrowth of Beard Hair with Ruxolitinib in an Alopecia Universalis Patient.

While most alopecia areata (AA) cases resolve spontaneously, the more severe types of AA, alopecia totalis (AT) and alopecia universalis (AU), can be highly resistant to therapy. We report on a 33-year-old ultraorthodox Jewish man with an 11-year history of AA that resulted in complete loss of the scalp and body hair 7 years ago. Previous treatments with intralesional and systemic corticosteroids had only partial and temporary effects. The patient was treated with ruxolitinib, 20 mg twice daily, resulting in complete growth of the beard after 4 months of treatment. The beard has a special significance for ultraorthodox Jews, and loss of the beard hair can have marked social and psychological consequences in AA patients. The Janus kinase (JAK) inhibitors have recently emerged as an effective treatment modality in AA, including the more severe forms, such as AT or AU. This report highlights the beneficial effects of the JAK inhibitors, especially in populations where the hair has a special importance due to cultural and religious backgrounds.
