Nail biting is related to skin picking and hair pulling. Skin picking, hair pulling and nail biting are labeled as Obsessive-Compulsive Disorders or OCD.

Nail biting shares many similarities to smoking. It is a ritualistic, physical habit. Either can be caused by the mechanics of a physical routine, or can be indicative of deeper psychological root causes.

If you have ever attempted to quit your nail biting habit, you know just how challenging is. Perhaps you have put on bandages or gloves over your fingertips, or tried bitter-flavored nail polish.
