The hair loss she won't explain

A 16-year-old has noticeable, patchy hair loss that has developed gradually over the past year. She describes a recurring urge to pull out individual hairs, building tension beforehand and a sense of relief while doing it, often without fully noticing until a noticeable bald patch has formed. A dermatological examination has ruled out any skin or hair-follicle disease, and she reports she has tried and failed to stop on her own.
