Healthy nails are an indication of overall good health. Nails tend to grow faster in younger individuals and slow down as we age. The speed at which your nails grow is influenced by a combination of genetic, lifestyle, and health factors. While there are no scientifically proven methods to make nails grow faster, a well-balanced diet rich in essential nutrients like biotin, protein, and vitamins can promote nail growth.

What You'll Learn

Diet and nutrition
Protein is essential for boosting the production of keratin, a fibrous structural protein that gives nails their strength and resilience. Animal proteins, such as chicken, turkey, and salmon, are great sources of protein and collagen, which are crucial for nail health. For those following a plant-based diet, dark, leafy greens, quinoa, almonds, cashews, peanuts, edamame, and black beans are good sources of protein.
In addition to protein, consuming a variety of vitamins and minerals is vital for nail health. Biotin, also known as vitamin B7, helps strengthen brittle nails and improve their growth. Foods rich in biotin include organ meats, egg yolk, dairy products, yeast, salmon, avocado, sweet potato, nuts, seeds, and cauliflower. Vitamin B12 and iron are also necessary for keeping nails strong and healthy, with deficiencies leading to potential nail discolouration.
Magnesium is another important mineral, as it helps with protein synthesis and the formation of new nails. Whole grains, specifically whole wheat, are a rich source of magnesium, along with dark, leafy green vegetables, quinoa, almonds, cashews, peanuts, edamame, and black beans.
Lastly, staying properly hydrated is vital for nail health. Ensuring adequate water intake helps support the body's overall functioning, including the growth of strong and healthy nails.
While diet and nutrition are fundamental to nail health, it is important to note that they are not the sole factors influencing nail growth. Other aspects, such as age, hormones, and overall health, also play a role in nail growth rate.

Lifestyle factors
Diet
Eating a well-balanced diet is crucial for nail health. Nails require a variety of nutrients, including proteins, vitamins, minerals, and healthy fats. Specifically, biotin, a type of B vitamin, has been linked to improved nail health and strength. A deficiency in certain nutrients, such as iron, can lead to brittle or dented nails. Therefore, ensuring a diverse and nutrient-rich diet is essential for supporting nail growth and strength.
Nail Care and Grooming
Practicing good nail hygiene and grooming habits is another essential lifestyle factor. This includes keeping nails clean, trimming them regularly, and moisturizing the nails and cuticles. It is also important to avoid nail-biting and cutting nails too short, as this can lead to nail problems and slower growth. Additionally, using nail hardeners sparingly may help strengthen nails and prevent breakage.
Sun Exposure
Some individuals have suggested that sun exposure may influence nail growth. While this is not yet scientifically proven, it is worth considering as a potential factor affecting nail growth rates.
Trauma and Injury
Trauma or injury to the nail bed can significantly impact nail growth. Nail-biting, using nails as tools, or picking at cuticles can slow nail growth and even lead to nail malformations. Protecting the nails from injury and allowing adequate time for healing are crucial for maintaining healthy nail growth.
While lifestyle factors play a role in nail growth, it is important to remember that genetics and overall health also contribute significantly to the rate of nail growth. Each person's nails are unique, and a combination of factors influences the speed at which they grow.

Genetics
The growth of nails is influenced by matrix cells, which are located under the skin at the base of the nail. These cells divide and push older cells forward, causing the nail to grow. This growth is influenced by various factors, including genetics, overall health, nutrition, hormones, age, blood circulation, exposure to injury or trauma, and the environment.
Genetic predisposition can result in a faster nail growth rate. For instance, younger individuals typically experience faster nail growth compared to older adults due to the slowing metabolism and cell division associated with ageing. Additionally, good overall health and a balanced diet rich in essential nutrients like biotin, protein, and vitamins A, D, and B7 (biotin) can promote nail growth.
While genetics play a key role in nail growth rates, it is important to note that environmental and external factors also influence nail growth. For example, warmer climates tend to promote faster nail growth compared to colder ones due to increased blood circulation, which delivers essential nutrients to the nail matrix. Additionally, frequent nail clipping and maintaining clean and well-maintained nails can also stimulate faster growth.

Health
The speed at which nails grow is influenced by a combination of genetic, lifestyle, and health factors. While there are no scientifically proven methods to make nails grow faster, there are several ways to increase overall nail health.
Nails are primarily made of a protein called keratin. The nail plate, which is the hard part of the nail, does not consist of living tissue, so it is not possible to improve its health directly. However, the nail bed, the tissue underneath the nail, is key to good nail health. If the nail bed and the surrounding skin are healthy, it enables the nails to grow longer and stronger.
To support nail health, it is important to maintain a balanced diet rich in essential nutrients like biotin, protein, and vitamins. This includes consuming adequate amounts of calcium, iron, and vitamin D, as deficiencies in these nutrients can lead to weak, brittle, or dented nails. In addition to diet, moisturizing the nails and cuticles with lotion can help prevent breakage. Keeping nails clean and trimmed is another aspect of good nail hygiene, which can help maintain overall nail health.
While certain factors influencing nail growth are outside of one's control, such as age, hormone levels, and genetics, addressing nutritional deficiencies and maintaining a healthy lifestyle can promote stronger and healthier nails.

Nail care
Diet
A balanced diet rich in vitamins and minerals is vital for healthy nails. Include biotin, found in eggs, almonds, and avocados, to promote nail growth and strength. Vitamin E, an antioxidant found in spinach and nuts, helps repair damaged nails. Consuming iron, found in red meat, lentils, and leafy greens, is essential for preventing brittle nails. Nails are made of keratin, a type of protein, so increasing your intake of keratin-rich foods such as eggs, sweet potatoes, and kale can bolster your nail care routine.
Moisturise
Moisturising your hands and nails with a lotion is important, especially at the base of the nails where the cuticles are located. Cuticles seal the gap between the nail plate and finger, preventing infection. Serum-like strengtheners are absorbed quickly and typically contain moisturisers to rehydrate dry, brittle nails.
Trim and File
Consistent trims are important for nail care. Keep your nails trimmed to a short length and use a brush to scrub beneath the tip with soap. Aim to clip them every one to two weeks, adjusting the frequency as needed. Glass or crystal nail files are recommended over emery boards as they create an even edge and can be used on weak, brittle, and damaged nails.
Protect
If your job or workout routine exposes your nails to potential damage, keep a nail file handy for on-the-spot buffing of any rough edges. Wear rubber gloves when doing chores such as washing dishes to protect your nails and avoid further treatment.
Avoid Biting
Avoid biting your nails or pulling at hangnails, as this could damage the nail and irritate the surrounding skin.
