This is an observational study for people with alopecia areata (AA), a condition that causes hair loss. The study aims to understand the long-term safety and effectiveness of treatments for AA that are already approved. Researchers will collect information on how AA affects people, how it progresses, and how different treatments work in real-world settings. You can join if you are at least 18 years old, have been diagnosed with AA by a dermatologist, and are currently prescribed or starting an eligible medication for AA. The study will follow participants for at least 10 years to understand the long-term effects of treatments and the disease itself. This will help doctors and patients make better decisions about AA care.
