10 tips to stop biting your nails

These aren’t complicated treatments or weird products for your nails that might end up affecting you.

If you incorporate these simple tips into your daily life and you really put your mind to it, you’ll achieve your goals.

Tip 1: Self-knowledge and liberation

First, you should identify the situations that activate your need to bite your nails like caressing, touching, feeling, rubbing or scratching your nails which lead directly to you putting them in your mouth.

The second step is to identify the times when your habit gets activated like tests, before you make certain decisions, etc.

The third and final step is to choose the activities that avoid this stress cycle and keep your hands busy: they should be things that you like doing like sports, dancing, playing a musical instrument, etc.

That way you’ll channel your anxiety and you won’t hurt your nails.

Tip 2: Substitute with plants

Start chewing on edible plants like licorice root (slowly). That way you won’t be biting your nails but you’ll keep your mouth busy.

You need to carry the plants with you in stressful situations; they’ll help you focus.

Tip 3: Sugar-free gum


It’s a good idea to chew gum or mints whenever you feel an uncontrollable desire to bite your nails.

This is a win-win-win: your mouth will be busy, your breath fresh and you’ll avoid getting wrinkles because of the jaw muscle movements.

Tip 4: Aloe vera

The Aloe vera plant has many health properties but it tastes terrible. Peel an aloe vera leaf and cut it into chunks.

Put them in the fridge and rub your nails with a piece every morning.

I promise that after you taste them for the first time you’ll keep your nails far away from your mouth.

Tip 5: Self-control exercise

This exercise will help you control your desire to bite your nails:

  1. Put your finger two inches from your mouth.
  2. Pull it away.
  3. Do this several times, bringing your finger closer and closer to your mouth.
  4. Try putting your finger in your mouth for a few minutes without biting your nail. Repeat.

Do this exercise for a few minutes every day and I promise you’ll be surprised by the results.

Tip 6: Fake nails


Put on acrylic nails. That will let your nails grow and make it impossible for you to bite them.

If you spend money on your nails, you’ll go to great lengths to not ruin them by biting on them.

Tip 7: Nail band-aids

Put band-aids on your nails and leave them on a few days (you can change them every time you take a shower).

The idea is for you to take off the band-aid and see how beautiful your nails look healthy. Repeat as many times as necessary.

Tip 8: Pick up a hobby

This activity will distract you, keep you from biting your nails and at the same time, you’ll discover a new passion.

It might be decorating your house, knitting, running or other outdoor activities even, who knows, give your friends manicures.

I recommend one that includes getting your hands dirty like anything to do with dirt or plaster.

Tip 9: Gloves

If you like gloves, use them. They’re a great way to prevent onychophagia.

Tip 10: Celebrate your success

Celebrate your nails. Talk about how good they’re looking. Encouragement from your friends and family will help you keep them healthy and beautiful.

It’s more about skill than strength

Now you have several ways to prevent onychophagia and get it out of your life forever. Don’t get depressed.

Little by little you’ll achieve your goal, it’s just a matter of thinking it through and aiming for it.

Choose your tips to stop your nail biting and keep your hands healthy and beautiful.
