How is Trichotillomania treated?

There is no one "gold standard" treatment for TTM. The usual method I use involves first of all keeping a detailed diary of the pulling and trying to understand in as much detail as possible the what, when, where, how and why of pulling and then using this information to custom design interventions based upon this information. Most experts believe the purpose of the pulling is some sort of nervous system regulation. Somehow the pulling helps TTM sufferers regulate their nervous systems in somewhat the same way most of us use a cup of coffee or going for a jog.
