What Is the Treatment for Trichotillomania?
The main treatment for trichotillomania is a type of behavior therapy called habit reversal training. Basically, this means replacing a bad habit with something else that's not harmful.
With this approach, people with trichotillomania first learn to identify when and where they have the urge to pull hair. They also learn to relax and do something else, that doesn't hurt them, as a way to help ease tension when they feel the urge to pull their hair.
