What You'll Learn

Genetics and health
Genetics play a significant role in determining the size and shape of nail beds. However, various factors related to health and lifestyle can influence nail growth and strength.
Nutrition is essential for nail health. A well-balanced diet rich in nutrients, including colourful fruits and vegetables, leafy greens, lean proteins, healthy fats, and adequate carbohydrates, promotes strong and healthy nails. Nails may reflect nutrient deficiencies, and a diet lacking crucial vitamins and minerals can affect nail growth and strength. Biotin, a type of B vitamin, is recommended as a supplement to strengthen nails, and studies suggest that a daily dose of 2.5 milligrams can improve nail strength. Additionally, collagen peptides, found in protein-rich foods, have been proven to improve nail health.
Hormones also influence nail growth, with younger people, men, and pregnant women tending to experience faster nail growth. Maintaining overall health is crucial, as poor health can cause abnormal nail growth. Certain medications and illnesses can contribute to slower nail growth, and nails may grow more slowly with age.
To maintain nail health, it is important to keep nails clean, dry, and moisturised. Regular nail grooming, including gentle trimming, filing, and moisturising, can boost nail strength and reduce breakage. Avoiding harsh chemicals, such as acetone-based nail polish removers, is essential to prevent nail brittleness.

Diet and supplements
A healthy diet is key to achieving longer nails. Nails are made of a fibrous structural protein called keratin, so eating enough protein is essential for boosting its production and creating strong nails. Animal foods like meat, poultry, fish, eggs, and dairy are good sources of protein, but it can also be found in plant foods such as soy, legumes, beans, lentils, nuts, seeds, and whole grains.
Biotin is another essential nutrient for nail growth, as it promotes healthy cell growth and aids in the metabolism of protein-building amino acids. It can be found in organ meats, egg yolk, dairy products, yeast, salmon, avocado, sweet potato, nuts, seeds, and even cauliflower.
Vitamin E is also important for nail health, as it helps protect nails from oxidative stress and environmental damage, improves blood circulation to the nail bed, and aids in moisture retention. Good sources of vitamin E include nuts, seeds, green leafy vegetables, fortified cereals, and vegetable oils.
In addition to these specific nutrients, a balanced diet that includes a variety of fruits, vegetables, nuts, and seeds is ideal for nail health. These foods provide essential vitamins, minerals, and antioxidants that contribute to overall health and well-being, including nail growth and strength.
While supplements are available for nail health, evidence suggests that consuming a variety of vitamins, minerals, and nutrients through food is the best way to improve and maintain nail health. However, in certain situations, supplements can be beneficial. For example, people with illnesses that affect nutrient absorption or those following a vegan or vegetarian diet may need supplements to meet their nutritional needs. It is always recommended to consult with a healthcare professional before starting any new supplement.

Nail maintenance
Keep Nails Clean and Dry
It is important to maintain proper hand and nail hygiene to prevent the growth of bacteria. Keep your nails dry, especially after washing your hands, to avoid moisture retention, which can lead to bacterial growth and nail damage.
Trim and File Regularly
Trimming your nails regularly helps prevent snagging and accidental breakage. Use sharp manicure scissors or clippers to cut your nails straight across, then round the tips into a soft curve. Avoid excessive buffing or filing as it can thin out your nails; instead, opt for gentle nail files and use them sparingly.
Moisturize and Strengthen
Moisturizing your hands and nails with lotion is essential for nail health. Pay special attention to the base of your nails, where the cuticles are located. You can also use nail hardeners or strengtheners, which are painted on like nail polish, to fortify your nails and reduce the risk of breakage.
Diet and Supplements
A well-balanced diet rich in nutrients is crucial for nail health. Include colourful fruits and vegetables, leafy greens, lean proteins, healthy fats, and plenty of water in your daily meals. Additionally, consider taking supplements like biotin, a type of B vitamin that strengthens nails and helps convert food into energy. Keratin supplements, either oral or topical, can also help build nail strength and resilience.
Protect from Chemicals and Trauma
Limit the use of harsh nail products containing chemicals like acetone, which can cause nails to become brittle and weak. Opt for gentler, non-acetone alternatives or natural nail polish removers. Additionally, try to avoid nail trauma, such as breaking a nail, as this can set back your nail growth progress.
By following these tips and maintaining a healthy lifestyle, you can achieve stronger, healthier, and longer nails.

Avoiding breakage
To prevent your nails from breaking, there are several strategies you can adopt. Firstly, maintaining nail hygiene is essential. Keep your nails dry and clean to prevent the growth of bacteria. It is also important to trim your nails regularly, using sharp manicure scissors or clippers, and rounding the tips of your nails into a soft curve. This will help reduce the risk of breakage by preventing your nails from snagging on things. However, avoid excessive buffing, filing, or cuticle cutting, as these practices can thin out your nails. Instead, opt for gentle nail files and use them sparingly.
Another way to avoid breakage is to protect your nails from chemicals. Nails can become brittle due to exposure to harsh chemicals like nail polish removers containing acetone. Therefore, it is advisable to limit the use of such products or choose gentler, non-acetone alternatives. Additionally, consider using nail hardeners or strengtheners, which can be painted on like nail polish. These products help protect and fortify your nails, reducing the chances of breakage.
Nutrition also plays a crucial role in nail health. A nutrient-dense and varied diet, including colourful fruits and vegetables, lean protein sources, and healthy fats, can promote stronger nails. Specifically, biotin, a type of B vitamin, is highly recommended to boost nail strength. Studies suggest that taking a daily biotin supplement or including biotin-rich foods in your diet can significantly improve nail thickness and hardness. Additionally, ensure you are drinking enough water throughout the day, as hydration is essential for nail health. Dehydration can lead to brittle, easily breakable nails.
Finally, consider using a builder gel or BIAB (Builder In a Bottle) to provide a protective layer for your natural nails. This thicker gel polish adds resilience and helps prevent chipping and breaking. Regular appointments for this treatment will support the growth of stronger, longer nails.

Biotin Supplements
Biotin, also known as vitamin H or vitamin B7, is a water-soluble vitamin that plays a crucial role in nail health. Studies suggest that taking a daily biotin supplement of 2.5 milligrams can significantly improve nail strength and hardness in just a few weeks. Biotin-rich foods or supplements may help strengthen brittle nails and promote overall nail health.
Nail Hardeners and Strengtheners
Nail hardeners and strengtheners are products painted onto nails like polish. These treatments fortify nails, reducing the chances of breakage and allowing them to grow longer. Dermatologist-approved nail strengtheners, such as ISDIN SI-Nails, are recommended for effective results.
Builder Gel (BIAB)
Builder gel, also known as BIAB, is a thicker gel polish that adds a protective layer to natural nails. This treatment helps prevent chipping and breaking, creating a resilient surface to reduce wear and tear. It is ideal for brittle and weak nails, providing structural support and allowing nails to grow longer and stronger.
Keratin Supplements
Keratin is the main protein that makes up nails. Taking a keratin supplement orally or applying it topically as an oil can help build nail strength and resiliency. Ingesting protein in the form of a keratin supplement and including protein-rich foods in your diet may positively impact nail health and growth.
Moisturizing and Hydration
Moisturized nails are healthier and less prone to breakage. Using nail lotions and oils can help maintain nail health and promote growth. Additionally, drinking enough water throughout the day is essential for nail health, as it helps nails retain moisture, preventing them from becoming brittle and prone to breakage.
These protective treatments provide a foundation for healthier and longer nails. By incorporating these strategies into your nail care routine, you can strengthen your nails and reduce the risk of breakage, allowing your nails to grow and flourish.
