Maybe I am behind on the times, but I have almost never heard of Trichotillomania being present in films. Yes I've seen it on My Strange Addiction and on an episode of Nip Tuck forever ago, but I've never seen it in a movie... Until Now. I was doing a little bit of research when I stumbled upon the Movie " Young Adult ". It came out in 2011 and starred Charlize Theron as its leading lady. According to IMDB it's about a woman who soon after her divorce, returns to her hometown to try and rekindle a romance with her ex-boyfriend who is now married with a newborn.I haven't seen the movie myself but in the trailer you can see her washing her wig at 0:33 and apparently in the opening scene you see her pulling.
