4. Use “Anti-Bite” Nail Polish
There is also nail polish on the market right now which will help you avoid biting your nails. This nail polish is manufactured with some kind of substance that makes your nails bitter to the touch.
That means that when you start biting them, you will immediately feel this bitter taste and you will not want to continue. Of course, nail polish is mostly for women because very few men wear it.
However, even for men, there is the clear nail polish that will not give away the fact that you are wearing and that has the same potential to prevent you from biting your nails.
If you do not want to buy commercially, then you can create your own anti-bite nail cover by using hot sauce or some other substance that you will not want to continue biting.
