There are many reasons why some people's nails grow faster than others. Firstly, genetics plays a significant role in determining the speed at which nails grow. If your parents or grandparents had fast-growing nails, you are likely to as well. Age also impacts nail growth, with younger people typically experiencing faster nail growth compared to older adults. Nails on the dominant hand also tend to grow faster, as they are more prone to trauma, which increases blood flow and circulation to the area. Additionally, good overall health and a balanced diet rich in essential nutrients like biotin, protein, and vitamins can promote nail growth. Sun exposure and hormones may also influence nail growth, with higher estrogen levels during pregnancy leading to faster nail growth.

Genetics and family history
Genetics influences not only the growth rate but also the size and shape of your nail beds. So, if your parents or siblings have large nail beds, you're likely to inherit that feature as well. While genetics is a crucial factor, it's important to remember that other factors also come into play and can impact the growth rate of your nails.
Age is one such factor. Generally, younger people experience faster nail growth due to their higher metabolism and more rapid cell division. As we age, our blood circulation slows down, and this can lead to a decrease in nail growth speed over time. A 2007 study observed that the rate of thumbnail growth for a 23-year-old was 0.123 mm per day, while at age 67, this rate had slowed to 0.095 mm per day.
Hormonal changes throughout life can also influence nail growth rates. Puberty, for instance, is a period of fluctuating hormone levels, and nail growth is said to peak during this time. Pregnancy is another phase where hormones can accelerate nail growth, while menopause and high levels of the stress hormone cortisol may lead to slower growth.
In addition to genetics and age, nutrient deficiencies can also impact nail growth. Nails require various vitamins and minerals to grow strong and healthy. Deficiencies in certain nutrients, such as iron and zinc, have been linked to nail breakage and overall slower growth. Therefore, maintaining a well-balanced diet that provides your body with the necessary nutrients is essential for optimal nail health and growth.

Nutrition and diet
A well-balanced and nutritious diet is essential for maintaining healthy nails. Nails are made of a hard protein called keratin, so consuming an adequate amount of protein is crucial for nail growth. A deficiency in protein can lead to weakened and slow-growing nails. Animal sources of protein include eggs, chicken, turkey, lean beef, pork, and fish. For vegetarians and vegans, lentils, peanuts, nuts, and dairy products are good alternatives.
In addition to protein, vitamins and minerals are also necessary for nail growth. A lack of iron, calcium, magnesium, B vitamins, vitamin C, and vitamin D can cause brittle nails or the appearance of horizontal ridges. Vitamin D deficiency, in particular, may result in dry and brittle nails. Salmon, eggs, and nutritional yeast are excellent sources of vitamin D and biotin, which is a type of B vitamin that helps convert food into energy. Consuming fatty acid-rich foods like flaxseed, which is high in omega-3 fatty acids, can promote healthy cell development and aid in nail growth.
Hydration is another key factor in nail health. Water aids in delivering nutrients and oxygen to the cells, so staying properly hydrated helps prevent brittle, dry nails that break easily. In addition to water, hydrating liquids and foods such as fruits, vegetables, yogurt, and soups can also help maintain hydration.
While a healthy diet is important, it is worth noting that there is no scientifically proven method for making nails grow faster. However, a well-balanced diet rich in essential nutrients like biotin, protein, and vitamins can promote stronger and healthier nails.

Blood circulation
Nail biting, or onychophagia, has been associated with faster nail growth. This is because the trauma caused by nail-biting stimulates circulation in the nail bed, promoting growth. Similarly, frequent nail clipping may also contribute to slightly faster nail growth. However, it is important to note that regular nail clipping is safer than nail-biting and is recommended for maintaining nail health.
The rate of nail growth can vary depending on various factors, including finger length, dominance of the hand, and season. Nails on longer fingers and dominant hands tend to grow faster due to increased usage, which can lead to more trauma and increased circulation in the nail bed. Additionally, nails tend to grow faster during the summertime, possibly due to increased circulation or other seasonal factors.
While there are no scientifically proven methods to make nails grow faster, maintaining overall nail health is crucial. This includes practicing good nail hygiene, keeping nails clean and trimmed, and addressing any nutritional deficiencies or underlying health conditions that may impact nail growth. Additionally, taking biotin supplements and using nail hardeners sparingly can help strengthen nails and prevent breakage, allowing them to grow longer.
In summary, blood circulation is integral to nail growth. Poor circulation can hinder nail growth, while healthy circulation promotes it. By understanding the factors that affect circulation and nail health, individuals can take appropriate steps to support optimal nail growth and overall well-being.

Hormones
Oestrogen, a sex hormone, is responsible for keeping water in body tissues, and thus, lower oestrogen levels can lead to dull and brittle fingernails. During pregnancy, oestrogen and progesterone levels are at their highest, resulting in rapid nail growth for many women. Conversely, women experiencing a drop in oestrogen levels, such as during menopause or postpartum, may notice changes in their nails, including dryness and thinning.
Additionally, androgen hormones like testosterone and DHEA influence hair growth. An imbalance in testosterone metabolites can lead to hair loss and the growth of unwanted body hair. Testosterone is also necessary for protein synthesis, particularly keratin, which is essential for nail health. Parathyroid hormone, produced by the parathyroid glands, regulates calcium and vitamin D levels. A deficiency in this hormone can result in brittle nails, which can be addressed by supplementing with calcium and vitamin D.
Hormonal changes due to medical conditions, such as thyroid problems or cancer, can also impact nail health. For example, thyroid disease can cause onycholysis, leading to nail loosening and softening. Similarly, chemotherapy can affect the entire body, including nail health. It is important to monitor any changes in your nails and consult a healthcare practitioner if you have any concerns.

Age
As you grow older, your nails may become thicker or thinner. Conditions like psoriasis and rheumatoid arthritis can result in thicker nails. Toenails are particularly vulnerable to fungal infections, which account for about half of all nail disorders in older people. Fungal infections can cause nail thickening and discoloration.
With age, nails may also become more brittle and prone to breaking. Repeated wetting and drying, or exposure to harsh cleaning chemicals or cosmetics, can worsen this problem. Nails may also become dull and lose their colour, changing from translucent to yellowed and opaque.
The tips of the fingernails may fragment, and lengthwise ridges may develop. These ridges can be a normal sign of ageing, but they can also indicate a more serious condition, such as skin cancer. Dark stripes or ridges are more common in darker-skinned individuals, such as Hispanics and African Americans, as they age.
