Habit Reversal Training (HRT) is an evidence-based type of behavioral therapy that combines several different steps to target conditions such as trichotillomania (hair pulling), tics, Tourette Syndrome, and excoriation (skin picking). The first step is to become aware of the thoughts, sensations, feelings, and urges that precede these behaviors. Eventually, a competing response which is incompatible with these behaviors is introduced and practiced when a person has the urge to engage in hair pulling or skin picking, which weakens this cycle.
