Nail-biting is a common habit, but it can lead to infections and damage to the teeth and jaw. Researchers believe that nail biting stimulates the growth plate of each finger, leading to faster nail growth. Factors such as age, season, overall health, medications, diseases, nutritional status, injuries, temperature changes, and genetics can also affect nail growth. While nails typically grow at 0.7mm per week, former nail-biters have reported that their nail beds have lengthened after quitting. To quit nail-biting, individuals can try keeping a diary of triggers, trimming nails short, and using nail-biting deterrents or treatments.

What You'll Learn
Factors affecting nail growth
Fingernails grow on average about a tenth of a millimeter per day or around 0.7 mm per week. However, several factors can influence the rate of nail growth. These include age, overall health, hormone levels, the season, and which hand or finger the nail is on.
Age is a factor that affects nail growth, with older individuals experiencing slower nail growth than younger people. This may be due to a decrease in blood circulation with age. For example, a study observed that between the ages of 23 and 67, the rate of nail growth decreased from 0.123 mm per day to 0.095 mm per day.
Overall health and hormone levels also play a role in nail growth. Certain health conditions, such as peripheral artery disease (PAD), can reduce blood flow to the nails, slowing nail growth. Additionally, illnesses like COVID-19, pneumonia, or a heart attack can interrupt nail growth and cause horizontal ridges known as Beau's lines. Hormone levels can affect nail growth, with pregnancy resulting in rapid nail growth, while lactation may decrease nail growth. Puberty is also a time when nail growth is accelerated due to fluctuating hormone levels.
The season can influence nail growth, with nails growing faster during the summer months. This variation may be attributed to factors such as nutrition, sunlight exposure, and vitamin D levels, which can impact nail growth.
Another factor is the hand preference, with nails on the dominant hand tending to grow faster. Similarly, within each hand, the nails on the longer fingers, such as the index and middle fingers, generally grow more quickly than those on the little finger.

Nail biting and infections
Nail biting, or onychophagia, is a common habit, with up to 30% of the population biting their nails. However, it can cause various issues, including infections.
Nail biting can create cracks in the skin that allow bacteria to enter and cause an infection called paronychia. Paronychia can also be caused by trauma to the nail bed or cuticle area, which can result from nail biting. This infection can lead to reddening, pus buildup, tenderness, and warmness in the infected area. If left untreated, paronychia can cause the nail to grow abnormally and may result in the nail detaching from the nail bed and falling off. In severe cases, the infection can spread to the underlying bone, and the infected finger or toe may need to be amputated to prevent further spread.
Additionally, nail biters may develop hangnails, which are tiny, torn pieces of skin next to the nail. Hangnails can lead to infection if not properly treated. Ingrown nails, another potential complication of nail biting, can be extremely painful and carry a high risk of infection.
The pathogens that transfer from nails to the mouth during nail-biting can also cause stomach or intestinal infections. Furthermore, nail biters who paint their nails may be at risk from the toxins present in nail polishes and gels, such as formaldehyde, toluene, and dibutyl phthalate. These chemicals can be harmful to the body with long-term exposure.
To reduce the risk of infection, it is important for nail biters to quit the habit. This can be challenging, but various techniques can help, such as using a bitter-tasting nail polish, getting frequent manicures, and keeping nails trimmed short.

Healing nails after biting
Once the habit is under control, the nails can begin to heal. This process can take a few months, depending on the level of damage. Creating a nail care routine is important, which includes regularly moisturising the nails and cuticles, using cuticle oil, and applying nail hardener. Nutrition also plays a role in nail health, so ensuring a proper diet is essential.
It is normal to experience relapses when trying to stop nail-biting, and it may take a few attempts to successfully break the habit. Consulting a doctor or dermatologist is recommended if nail-biting persists and is causing infections or other serious issues.
With consistent care and patience, bitten nails can heal and grow back stronger and healthier.

Nail care routine
Nail biting is a common habit that can lead to infections and damage to the teeth and jaw. It can also cause scarring and damage to the skin around the nail. However, provided the nail bed is not damaged, your nails should recover after a few months of healing and healthy new growth. Nails typically grow around 0.7 mm per week, but this can vary depending on factors such as age, season, and overall health.
Keep Your Nails Trimmed
It is essential to keep your nails trimmed to a comfortable length. Nails that are too long can become thin and prone to breaking, splitting, or tearing, which can be painful and hinder daily activities. Keeping your nails at a manageable length can also make it easier to break the habit of nail biting.
Moisturize Your Hands and Nails
Apply moisturizer to your hands and nails regularly to prevent cracking and maintain nail health. This is especially important after washing your hands or when your hands feel dry. Look for moisturizers that contain hydrating ingredients such as shea butter, aloe vera, or vitamin E, which can benefit both your skin and nails.
Use Cuticle Oil
Cuticle oil can help protect your nails against damage by providing extra nutrients. It can also help to soften and moisturize your cuticles, promoting healthy nail growth. Massage a small amount of cuticle oil into your nail beds and cuticles, allowing it to absorb and nourish your nails.
Take Care of Hangnails
To deal with hangnails, soak your fingers in warm water to soften the loose skin. Then, use tweezers to gently remove the loose hangnail. Taking care of hangnails as soon as they appear will help prevent further tearing and potential pain.
Take Vitamins
Vitamins such as biotin can help support nail health and strength. Consult with your healthcare provider to determine if vitamin supplements are right for you and to ensure you are taking the appropriate dosage.
Maintain Clean Nails
Keep your nails clean and dry to prevent bacterial growth and potential infections. Wash your hands regularly and ensure your nails are thoroughly dried afterward, especially after any activities that involve water or moisture.
Identify and Address Nail Biting Triggers
Nail biting is often an unconscious habit, and identifying the underlying reasons behind it can help you address and break the habit. Keeping a diary of your triggers can help you become more mindful of when and why you bite your nails, allowing you to find healthier coping mechanisms or distractions.
Remember, nail care is for everyone, and it is essential to customize your routine to fit your specific needs and preferences. With consistent care and patience, you can improve your nail health and say goodbye to nail biting!

Trimming nails
Trimming your nails is an important part of nail care. It not only makes your nails look neat and tidy but also helps to keep them healthy. Short nails are less likely to harbour dirt and bacteria, reducing the risk of infection. Additionally, trimming your nails can help you break the habit of nail-biting, as short nails may be less satisfying to bite. Here are some tips for trimming your nails effectively:
Tools and Timing:
Use the appropriate tools for trimming your nails, such as nail clippers or nail scissors for fingernails and toenail clippers for toenails. It is important to keep your nail-cutting tools clean to prevent the spread of bacteria. Disinfect your tools regularly by soaking a scrub brush in isopropyl alcohol and using it to scrub your clippers or scissors. Rinse and dry them thoroughly before putting them away. The best time to trim your nails is after taking a bath or shower when your nails are softer and easier to cut.
Technique:
When trimming your fingernails, cut almost straight across the nail, leaving a small amount of white showing. Use a nail file to gently round the corners, softening any sharp angles. This helps keep your nails strong and prevents them from catching on fabrics or surfaces. For toenails, cut straight across to reduce the risk of ingrown toenails.
Aftercare:
Moisturize your nails and cuticles after trimming to maintain nail flexibility and promote healthy nail growth. This is especially important during dry seasons, as dry nails are more prone to splitting. Wash your hands after trimming to ensure cleanliness, and be mindful of any changes in your nails' colour, texture, or shape, as these could be indicators of underlying health issues.
Safety:
Be careful not to cut your nails too short, especially if you have a history of nail biting. Cutting too deeply can be painful and may damage the nail bed. If you have a short nail bed due to previous nail biting, be cautious when pushing back your cuticles, as this can make your nails more susceptible to bacterial infections.
By following these tips, you can effectively trim your nails, promoting both their health and aesthetic appeal.
