Dr. Mouton-Odum, PhD discusses that trichotillomania is treated with cognitive-behavioral therapy (CBT). This treatment helps a person identify what internal or external triggers cause their hair-pulling behavior. Internal triggers may be thoughts, beliefs, physical sensations, sensory experiences, or emotions. External triggers include places, activities, environment, time of day, or the presence or absence of another person. When those triggers are identified, the person with trichotillomania can be helped with changing the aspects of their environment and their internal triggers. If a person is experiencing a co-morbid disorder such as obsessive-compulsive disorder or depression, the therapist looks at whichever issue is more urgent.
