It's actually my 12 yr old son who has it. We've tried to keep it under control by shaving his head, but he still manages to pull it out either with his fingers or the tweezers. He pulls just about everywhere on his head: scalp, eyebrows, eyelashes. The school is nice enough to let him wear a hat all day so he doesn't get teased. It's bad enough that he's got ADHD and is on Focalin and Zoloft.
Does anyone else have the book "The Hair Pulling "Habit" and You: How to Solve the Trichotillomania Puzzle"? We're upto chapter 3, but he hates reading and homework so it's a struggle sometimes, lol.
