Summary

This study is monitoring the safety and effectiveness of Litfulo (Ritlecitinib) in 3,000 people with severe alopecia areata, a condition causing patchy hair loss. Participants take the drug as prescribed in real-world clinics across Korea. Researchers will track side effects and hair regrowth over 48 weeks.
