The phenomenon of trichotillomania, or hair pulling, has been observed for centuries. The ancient Greek physician Hippocrates noted hair pulling as one of the many symptoms that the physician was advised to assess as routine matter. In modern culture, pulling one's hair out is more typically referred to in the context of depression, frustration, boredom, or emotional turmoil. In truth, hair pulling is a highly prevalent behaviour that may be associated with significant morbidity.
