Nail biting is a common habit that often begins in childhood and can continue into adulthood. While it may not directly affect the growth of nails, it can damage the tissue that promotes nail growth and cause abnormal-looking nails. To grow your nails, you must first address the nail-biting habit. This involves identifying triggers, such as stress or anxiety, and gradually breaking the habit by avoiding these triggers and finding alternatives to biting. Maintaining short nails and using bitter-tasting nail polish can also deter biting. Once the habit is under control, you can focus on growing your nails by using nail strengtheners, cuticle oils, and maintaining a healthy diet with vitamins and protein. Painting your nails can also help protect them and provide strength. With patience and dedication, you can break the nail-biting habit and achieve the long, healthy nails you desire.

What You'll Learn

Identify triggers and causes, such as boredom, stress or anxiety
Nail biting, also called onychophagia, is a common habit, with estimates suggesting that 20 to 30% of people bite their nails. It often begins in childhood and can continue into adulthood. While it may start as a coping mechanism for feelings of boredom, stress, anxiety, loneliness, or even hunger, it can be difficult to break the habit once it forms.
Identifying your triggers is a critical step in stopping nail-biting. These triggers can be physical, such as the presence of hangnails, or emotional, such as boredom, stress, or anxiety. By understanding what causes you to bite your nails, you can develop strategies to avoid or manage these triggers effectively. For example, if you bite your nails when anxious or stressed, finding alternative ways to cope with stress, such as exercise or meditation, may help reduce the urge to bite your nails. If boredom is a trigger, finding ways to stay stimulated and engaged can be beneficial. This may include keeping your hands busy with a stress ball or fidget toy, or engaging in activities that require the use of your hands, such as knitting or drawing.
In some cases, nail biting may be a sign of a more serious underlying issue or a side effect of medication. If you've repeatedly tried to quit nail biting without success, it may be helpful to consult a doctor or seek professional treatment. A specific form of therapy called Habit Reversal Training (HRT) focuses on identifying triggers and developing replacement behaviours, and it has been shown to be effective in treating BFRBs like nail biting. Additionally, cognitive-behavioural therapy (CBT) and acceptance and commitment therapy (ACT) have also been found to be beneficial in some cases.
It's important to note that nail biting can have negative consequences, such as damaging the tissue that makes nails grow, leading to abnormal-looking nails, and increasing the risk of bacterial infections by transferring bacteria from your mouth to your fingers and face. Breaking the nail-biting habit can not only improve the appearance of your nails but also promote better overall health.

Try a gradual approach to breaking the habit
Nail biting is a common habit that often begins in childhood and can continue into adulthood. It can be challenging to break this habit, but a gradual approach can be effective. Here are some tips to help you gradually stop biting your nails:
Identify your triggers: Recognize the physical and emotional triggers that lead you to bite your nails. Physical triggers may include the presence of hangnails or dry skin around your nails. Emotional triggers could include stress, anxiety, or boredom. By understanding your triggers, you can develop strategies to avoid or manage these situations effectively.
Take a gradual approach to breaking the habit: Instead of trying to stop nail biting cold turkey, focus on one set of nails at a time. For example, start with your thumbnails and work on eliminating the habit there. Once you've successfully stopped biting your thumbnails, move on to your pinky nails or pointer nails. Gradually work your way through each finger or hand until you no longer bite any of your nails.
Maintain short nails: Keep your nails trimmed short, as having less nail to bite can reduce the temptation. Short nails are also less likely to break or snag, which can be a trigger for nail biting. Filing your nails with a fine glass file is recommended over cutting them, as it is less damaging to your nails.
Apply bitter-tasting nail polish: Using a bitter-tasting nail polish can act as a deterrent when you feel the urge to bite your nails. This safe and effective method is available over the counter and can help train your brain to associate nail-biting with an unpleasant taste.
Keep your nails looking their best: When your nails look good, you may be less likely to bite them. Consider getting a manicure or applying nail polish to make your nails look neat and presentable. You can also use nail strengthener products to help your nails grow stronger and healthier, reducing the urge to bite them.
Breaking the nail-biting habit takes time and patience. Be kind to yourself, and remember that relapses are normal. If you find that you've started biting your nails again, don't be discouraged. Simply start over and continue working towards your goal of healthier nails.

Use bitter-tasting nail polish to discourage nail biting
Using bitter-tasting nail polish is a common method to stop biting your nails. This safe but awful-tasting formula discourages many people from biting their nails. The nail polish contains bitter ingredients that leave an unpleasant taste in your mouth, making it less appealing to bite your nails.
There are several bitter nail polish products on the market, such as Onyx Professional Stop The Bite, which uses denatonium benzoate as its active ingredient. This ingredient is extremely bitter, and most people will not want to lick their fingers more than once after tasting it. Mavala Stop is another popular product that has been selling for over 30 years, but it is not recommended due to safety concerns and its high price. It is important to note that these products are best for occasional nail biters, as the active ingredients should not be ingested in large quantities.
Some people may prefer to adjust the bitterness level of their nail polish to make it even less appealing to bite their nails. Magique NoBite offers this option, and it is also free from toluene and many other chemicals found in regular nail polishes, making it safer for children. However, mixing the bitter additive into the base solution can be messy, and it may not last as long as other products.
When choosing a bitter nail polish, it is essential to consider the quality and safety of the product. Some polishes may be made in uncontrolled factories with questionable ingredients, while others may be certified gluten-free and safe for people with gluten intolerance or celiac disease. It is also worth noting that some polishes can be expensive, while others may offer free accessories.
While using bitter-tasting nail polish can be an effective way to stop nail biting, it is not the only method. Some alternative approaches include keeping your nails short, covering them with tape, or wearing gloves. Additionally, identifying your triggers, such as boredom, stress, or anxiety, can help you develop a plan to avoid nail biting.

Keep your nails painted and well-maintained to prevent biting
Painting your nails is a great way to prevent nail biting. Firstly, you are less likely to bite your nails if they look nice, or if you have spent money on getting them done in a salon. You can also add decals, designs, and nail art to elevate your manicure and further deter yourself from biting your nails.
Secondly, nail polish has a different texture from bare nails, and the feeling of nail polish on your teeth will remind you to avoid biting. Regular nail polish also has a bad taste, which will help you avoid biting. You can also purchase bitter-tasting nail polish, which is specifically designed to taste bad and discourage nail biting.
Thirdly, painting your nails can help protect them and provide a bit of extra strength so they don't bend or flex as much. This is especially helpful if your nails are prone to breaking and tearing, which can prompt you to bite the rest of your nails to make them all the same size.
Finally, painting your nails can be a fun hobby and a creative outlet, which can help curb your nail-biting habit. You can also try clay projects or plaster, as the flavour stays on your fingers for a long time, discouraging you from biting them.

Take vitamins and use nail oils to strengthen nails
Taking vitamins and using nail oils can help strengthen nails, which is essential if you're trying to grow your nails after biting them.
Vitamins
Vitamins, minerals, and nutrients are vital for supporting the growth, formation, and strength of new nail cells. A well-balanced diet that includes vegetables, fruits, grains, lean proteins, and healthy fats should provide your body with all the vitamins and minerals it needs to keep your nails strong and healthy. However, if you feel that you're not getting enough vitamins from your diet alone, you may consider taking supplements.
When it comes to nail health, some of the most important vitamins include:
- Biotin (Vitamin B7): Promotes healthy cell growth and aids in the metabolism of protein-building amino acids essential for nail growth. Biotin-rich foods include organ meats, egg yolk, dairy products, yeast, salmon, avocado, sweet potato, nuts, seeds, and cauliflower.
- Vitamin B12: Plays a role in iron absorption and red blood cell development. Both iron and B12 are necessary for keeping nails strong and healthy. Vitamin B12 is primarily found in animal foods such as meat, poultry, fish, eggs, and dairy.
- Folate (Vitamin B9): Contributes to red blood cell formation and the development of new cells. Folate can be found in dark green vegetables, citrus fruits, beans, peas, lentils, nuts, seeds, and avocado.
- Vitamin A, Vitamin E, and Vitamin D: These vitamins, along with healthy fats, carbohydrates, and protein, are also important for skin, hair, and nail health.
Nail Oils
Nail oils can also help strengthen nails and improve their appearance. Oils such as jojoba, sweet almond, and argan are believed to moisturize and strengthen nails and cuticles. Jojoba oil, in particular, is highly recommended due to its ability to penetrate through the nail plate and be absorbed, helping to keep the layers of keratin bonded and reducing peeling. Lavender essential oil is another excellent option, as it possesses moisturizing properties that nourish dry cuticles and replenish lackluster nails.
To use nail oils effectively, apply them at least once a day, preferably before bed or after washing your hands/showering. You can also apply oil with or without nail polish, massaging it into the nail plate and cuticle. Additionally, consider combining nail oils with essential oils and vitamin E for an enhanced strengthening effect.
