According to NPR, the upcoming edition of the the American Psychiatric Association's DSM (Diagnostic and Statistical Manual of Mental Disorders) will put "pathological grooming" in the same category as obsessive compulsive disorder. Pathological grooming includes nail biting, hair pulling, and skin picking.
