First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two medicines, hydroxychloroquine and methotrexate, to see which works better for frontal fibrosing alopecia, a type of scarring hair loss that mainly affects women. About 50 adults who choose to start one of these treatments will be followed for up to 48 weeks. The goal is to measure how well each medicine controls disease activity and improves quality of life, helping doctors make better treatment recommendations.
