Skin and Hair Picking
Skin picking, hair pulling and nail biting are all examples of what is called Body Focused Repetitive Behaviors (BFRBs). At the most basic level, these behaviors satisfy an urge. Many people report an almost uncontrollable feeling of needing to do them. Pulling, picking or biting also seem to deliver a pleasurable or relaxed sensation. Doing these behaviors seem to have a soothing effect on the nervous system. This probably explains why so many sufferers dislike doing the behaviors, but find it difficult to stop. Depression and Anxiety disorders are also common with BFRBs. Therapy for these disorders include Cognitive Behavior Therapy (CBT), Awareness Training and Competing Response Training.
