Effectiveness and Safety of Tofacitinib in Patients With Recalcitrant Frontal Fibrosing Alopecia : A Pilot Study

This study aims to determine the efficacy and safety of tofacitinib therapy in Thai patients with recalcitrant frontal fibrosing alopecia. The main questions are 1. Does Tofacitinib significantly reduce Frontal Fibrosing Alopecia Severity Index (FFASI), Frontal Fibrosing Alopecia Severity Score (FFASS), Lichen Planopillaris Activity Index (LPPAI) compared to baseline and after 16 weeks? 2. Is Tofacitinib significantly different for adverse events compared to baseline and after 16 weeks? Participants will have a check-up in clinical and investigation and then get prescribed oral Tofacitinib 5 mg twice a day for 12 weeks. After that, they will have follow-up every 4 weeks until week 16.
