Millions of kids suffer from mental health disorders called Body Focused Repetitive Behaviors, or BFRBs, which are subconscious behaviors that are physical, repetitive movements or gestures of the hands, focused on the body.  They include but are not limited to: hair pulling (Trichotillomania), nail biting (Onychophagia), and skin picking (Dermatillomania / excoriation disorder).  For many kids, these disorders cause not only physical but emotional and mental harm and can affect their learning in school.
