Alopecia areata (AA) is a chronic, autoimmune skin disease characterized by non-scarring hair loss. Baricitinib, a Janus kinase inhibitor (JAKi), prevents hair loss and promotes hair regrowth by inhibiting the inflammatory Janus kinase-signal transducer and activator of transcription (JAK-STAT) signaling pathway involved in cytotoxic T cell responses targeting hair follicles. The introduction of JAKi has transformed treatment against severe AA.

We present the case of a young male with AU who experienced progressive and extensive whitening of his scalp and body hair following treatment with baricitinib.

We report a case of recalcitrant FD in a man in his 40s who experienced significant symptom improvement and hair regrowth following the initiation of tirzepatide for weight management.
