Over time, using a nibble inhibitor can help you to break your nail biting habit for good. If you don't want to splurge on a specific nibble inhibitor product, try applying some hand sanitizer or cream that doesn't taste so good instead.

If your nails are covered this way, you won't be able to get to them! This is a good technique for when you're sitting at home in the evenings, or in bed at night.

Keeping your nails in good condition will make them stronger and prettier-looking, making them less prone to breakage and more difficult to break.
