Great book on the topic of trichotillomania for all different kinds of audiences. Very informative and includes besides a lot of information and personal stories from sufferers, several questionnaires and a Habit Reversal treatment plan (in a form so it can be used by the reader of the book, either for him/herself, a client, or a loved one).
I was most impressed by the chapter that gives an overview of current theories on the source of trichotillomania, and one of the last chapters, which is a chapter on how to work with trichotillomania in children. The last one is not just important for parents and teachers to read, but also for adults who suffer from trichotillomania. They'll probably recognize parts of it from their own childhood. This makes it possible to identify the course of the disorder during the earlier years, which can help while working with HR.
