The average growth rate of fingernails is about 3.5 millimetres per month, and this can be affected by various factors. For instance, younger people tend to have faster-growing nails than older people, and men and pregnant women tend to experience faster nail growth. Additionally, genetics play a role in nail growth, with the strength, thickness, and growth rate inherited from parents. Maintaining nail health involves regular grooming, keeping nails filed, and avoiding biting or cutting them too short. A healthy diet that includes protein, water, fruits, vegetables, and essential vitamins and minerals also contributes to stronger nails and promotes growth.

Diet: Eat protein, water, fruits, vegetables, vitamins, and minerals
Diet plays a crucial role in achieving strong and healthy nails. Consuming a variety of vitamins, minerals, and nutrients through nutrient-dense foods is the best way to improve and maintain nail health.
Firstly, eating enough protein is essential for boosting keratin production, which is responsible for keeping your nails strong and resilient. Animal foods like meat, poultry, fish, eggs, and dairy are good sources of protein. However, plant-based options such as soy, legumes, beans, lentils, nuts, seeds, and whole grains also provide ample protein.
Secondly, biotin, a B-complex vitamin, promotes healthy cell growth and aids in the metabolism of protein-building amino acids, which are crucial for nail growth. While biotin deficiency is rare, consuming biotin-rich foods or supplements may help strengthen brittle nails. Organ meats, egg yolk, dairy products, yeast, salmon, avocado, sweet potato, nuts, seeds, and cauliflower are excellent sources of biotin.
Thirdly, vitamin C is essential for collagen production, which provides strength and integrity to your nails. Citrus fruits like oranges, strawberries, and kiwi are well-known sources of vitamin C. Additionally, bell peppers, green vegetables, and tomatoes are also rich in this nutrient.
Furthermore, zinc is required for the healthy growth and division of nail cells. Animal proteins such as beef, poultry, fish, and eggs are excellent sources of zinc. However, plant-based options like soy, chickpeas, black beans, nuts, and seeds also provide zinc.
Lastly, magnesium is a mineral that plays a vital role in protein synthesis, which is necessary for nail growth. Consuming whole grains, dark green leafy vegetables, quinoa, almonds, cashews, peanuts, and black beans can help ensure adequate magnesium intake, preventing vertical ridges in your nails.
In summary, a balanced diet rich in protein, biotin, vitamin C, zinc, and magnesium is key to promoting nail growth and maintaining strong and healthy nails.

Nail grooming: File nails into a rounded or squared shape to prevent snagging and breaking
Maintaining well-groomed nails is essential for nail care and can even reflect your overall health. Filing your nails into a rounded or squared shape can prevent snagging and breaking, and it can also discourage nail biting and picking.
Before filing your nails, it is important to trim them to the desired general shape. If you want squared nails, cut straight across the end of your nails with nail trimmers. If you prefer round nails, make 4-5 smaller cuts at the end of each nail to initiate the curved shape.
To achieve a squared shape, file perpendicular to the nail's tip until you attain a flat end. Then, gently file the outside edges to smooth them out. For a rounded shape, file the outside edges of your nail and work your way toward the centre, allowing for a smooth and gradual curve. Alternate filing each side of the nail to ensure a symmetrical curve.
There are many other nail shapes to choose from, such as oval, almond, coffin, and stiletto. The oval shape is great for maintaining long nails, as they are least likely to break off. Almond nails have tapered sides that meet at a rounded peak, resembling the nut. Coffin nails are long and narrow, with a squared-off tip. Stiletto nails are similar to almond nails but come to a sharper point.
When filing your nails, it is crucial to use the correct technique to avoid damaging your nails. Always file dry nails, as wet nails are more prone to splitting. Use smooth, gentle strokes in a single direction, filing down the length of the nail more often than towards your fingers. Avoid using too much pressure or filing back and forth, as these can weaken the nails.

Health: Poor health can cause abnormal nail growth
Poor health can indeed cause abnormal nail growth. Your nails can tell you a lot about your health. Nail abnormalities are common and can affect the shape, thickness, or colour of your nails.
Diet
A healthy diet is important for strong, fast-growing, and healthy nails. A varied and nutritious diet should include protein, water, fruits, vegetables, and a wide array of vitamins and minerals. People who do not get enough iron, for instance, may have brittle or dented nails. Some specific dietary changes can strengthen the nails and promote growth.
Age
Nail growth slows with age, and older people may experience more nail abnormalities.
Disease
Nail abnormalities can be a sign of disease. For example, white streaks or spots on the nails, known as leukonychia, can be caused by arsenic poisoning, heart disease, renal failure, pneumonia, or hypoalbuminemia. Dark streaks on the nails could be melanoma, the most serious type of skin cancer. Curved nails, or clubbing, can be a harmless trait, but they can also indicate disease, including heart or lung problems. Grooves and ridges in the centre of the thumb, known as washboard nails, may be caused by repeatedly pushing back the cuticles.
Infection
Nail infections are common and can be caused by fungi, bacteria, or viruses. Yeast infections can cause nail inflammation and changes in colour, texture, and shape. Bacterial infections may cause nail loss, and severe infections may cause pain and swelling. Viral warts can cause changes in the shape of the nail, and ingrown toenails may become infected.
Medications
Medications can also affect nail growth. Antibiotics can cause lifting of the nail from the nail bed, and chemotherapy medicines can impact nail growth.

Age: Nail growth slows with age
As you get older, your nails may change in appearance, texture, and growth rate. These changes are natural and to be expected, but some may indicate an underlying medical condition.
Nail growth slows with age. In healthy adults, the average fingernail growth rate is about 3.5 millimetres per month. However, this rate can vary, and older people tend to experience slower nail growth than younger people.
Several factors can influence nail growth and health. A well-rounded diet that includes protein, water, fruits, vegetables, vitamins, and minerals is essential for strong nails. For example, a lack of iron can lead to brittle or dented nails. Additionally, hormones play a role in nail growth, with men and pregnant women typically experiencing faster nail growth.
While nail changes with age are often normal, some changes may signal more serious health issues. For instance, longitudinal melanonychia, characterised by dark stripes on the nails, can be a sign of melanoma or malignant skin cancer. Changes in nail colour, such as yellowing or discolouration, could indicate fungal infections, nutritional deficiencies, trauma, or other problems. Ingrown toenails, common in older adults, can cause substantial pain and walking issues.
It is important to maintain good nail hygiene and grooming habits to encourage nail growth and strength. This includes regular trimming, moisturising, and avoiding nail-biting. If you notice significant or persistent changes in your nails' texture, thickness, colour, or shape, it is advisable to consult a healthcare professional. They can help determine if these changes are due to ageing or an underlying medical condition.

Genetics: Nail strength, thickness, and growth rate are inherited from parents
The growth rate, strength, and thickness of nails are all influenced by genetics. While nails are made of a tough, rigid protein called alpha-keratin, the shape, strength, and thickness of this protein structure are determined by genetics.
There are six primary nail bed types, each influencing how long the nail can grow and how well gels and extensions will last. For example, those with vertically long and almond-shaped nails tend to have strong and long-lasting nails that can go for weeks without noticeable changes in growth. On the other hand, sword-shaped nails are prone to splitting and peeling due to their genetic shape.
In addition to genetics, external factors such as dominant hand, finger length, age, hormone levels, and overall health can also affect nail growth rate. For instance, nails on the dominant hand and longer fingers tend to grow faster due to increased usage. Similarly, nail growth rates may increase during pregnancy due to hormonal changes but slow down during lactation. Peak nail growth typically occurs during puberty, then declines as hormone levels stabilise with age.
While the shape and strength of nails are largely influenced by genetics, proper nail care is essential to maintaining healthy nails. This includes regular nail treatments and avoiding unqualified or poorly trained nail technicians, as they can cause permanent damage.
