- Cold turkey: If quitting cold turkey is not an option, consider picking one or two nails to safeguard from biting. This way, you'll be able to easily compare how your well-tended nails stack up to the unpleasant bitten ones. Hopefully, this will provide enough incentive on "protecting" the rest by following suit.
- Distract yourself: Nail-biting is often a cause of stress or boredom, so find a distraction for either your hands or your mouth. Chew gum, suck on a Tootsie Pop, exercise, or file your nails, for instance.
- Visualize: Many self-help books will tell you to visualize what you want to get results. Picture yourself with gorgeous, nibble-free nails. Get started by taking before pictures of the present state of your nails to remind yourself of what you don't want. And if you really want to delve deeper into the mind, consider hypnosis or a Stop Nail Biting Subliminal CD ($16).
- Be bitter: Put a halt to the biting by using bad-tasting polishes or flavors, like Barielle's No Bite Pro Growth ($15), Orly's No Bite ($7), or tea tree oil, which helps heal skin, too.
- Get a manicure: Have your nails polished after a professional manicure or do it at home as incentive for keeping your nails looking pretty — and most importantly, out of your mouth.
