There are several factors that influence nail growth, including genetics, nutrition, blood circulation, hormones, overall health, age, exposure to injury or trauma, and the environment. While there are no scientifically proven methods to make nails grow faster, understanding these factors can help support healthy nail growth. For example, maintaining a healthy and active lifestyle, improving circulation through hand massages, and taking supplements like biotin can all contribute to stronger and healthier nails. Additionally, factors such as temperature, climate, and the type of work an individual does can also impact nail growth rates.

What You'll Learn
Genetics
An individual's genetics play a significant role in determining the speed at which their nails grow. Just like other aspects of physical appearance, nail growth is influenced by genes. If your parents or grandparents had fast-growing nails, you are likely to inherit this trait as well. Genetics determine the baseline nail growth rate and the thickness of the nail plate.
The rate of nail growth is also influenced by handedness. Nails tend to grow faster on one's dominant hand, possibly due to increased trauma risk, such as catching your nail on something or hitting it with a tool. This increased risk of injury can stimulate circulation in the nail bed, promoting faster nail growth. Additionally, the nails on longer fingers tend to grow faster than those on shorter fingers.
Age also plays a role in nail growth, with younger individuals typically experiencing faster nail growth compared to older adults due to a slowing metabolism and cell division that comes with ageing. Nail growth is fastest at about age 10 and then gradually slows down over a person's lifetime.
While genetics play a crucial role in nail growth, it is important to note that other factors, such as overall health, diet, nutrition, blood circulation, hormones, and environmental factors, can also influence the rate of nail growth.

Nutritional deficiencies
Zinc deficiency can cause Beau's lines (horizontal ridges) and white spots on your nails. Iron deficiency can cause vertical nail ridges and koilonychia (spoon nails), which have a scooped-out depression in the middle. Iron deficiency can also cause brittle nails, which may crack easily. Soft nails that break easily may be caused by overexposure to moisture or chemicals, but they can also be a sign of iron deficiency.
Protein deficiency and malnutrition associated with chronic alcoholism can also cause Beau's lines. Malnutrition can result in nail changes such as soft and thin nails, as well as impaired nail growth. Kwashiorkor, a nutritional syndrome caused by severe protein malnutrition, can lead to longitudinal melanonychia, which is a blackish discolouration of the nail plate.
Nail health is closely associated with overall health, and nutritional deficiencies can impact nail growth and appearance. Ensuring a balanced diet with sufficient vitamins, minerals, and nutrients can promote healthy nail growth and prevent nutritional deficiencies that may cause nail abnormalities.

Blood circulation
Additionally, biting nails can cause trauma to the nail bed, stimulating circulation and resulting in faster nail growth. This is supported by the observation that bitten nails tend to grow faster than healthy nails. However, it is important to note that nail biting can also lead to nail problems and potentially cause infections.
The proximity of the fingers to the heart, the central pump for blood circulation, may also contribute to the faster growth of fingernails compared to toenails. Fingernails typically grow about three times faster than toenails, with toenails taking significantly longer to regrow completely if lost or damaged.
Age also influences blood circulation and nail growth. As individuals age, blood circulation tends to slow down, which may contribute to the gradual decrease in nail growth rate over time. Hormonal changes associated with aging, such as menopause, can further impact nail growth rates.
Overall, blood circulation is a crucial factor in nail growth, affecting the delivery of nutrients and oxygen to the nails and influencing the rate of growth and recovery from traumas.

Hormones
Puberty is a critical period for hormone fluctuations and nail growth. Nail growth tends to peak during puberty and gradually declines as hormone levels stabilise with age. Additionally, younger individuals generally experience faster nail growth compared to older adults due to the influence of hormones and the slowing of metabolism and cell division over time.
Hormone changes related to pregnancy can also significantly impact nail growth. Pregnant women often exhibit faster nail growth due to increased estrogen levels. In contrast, during lactation, nail growth may slow down.
Overall health and certain health conditions can also influence nail growth. For example, individuals with diabetes or circulatory issues may experience differences in nail growth rates and should closely monitor their nails. Maintaining a nutritious, well-balanced diet and good nail hygiene can support nail health and growth.
While there are no scientifically proven methods to accelerate nail growth, taking care of your health and nails can promote stronger and longer nails over time. This includes proper nutrition, such as consuming a balanced diet rich in essential nutrients like biotin, protein, and vitamins, and lean sources of protein. Additionally, maintaining good nail hygiene and care routines can prevent breakage and support nail growth.

Trauma
When you sustain nail trauma, the impact can disrupt the normal growth cycle, which begins in the nail matrix. Trauma can interfere with the production of healthy cells, causing the nail to grow unevenly or distortedly. Sometimes, the nail may grow more slowly or even stop growing temporarily as it recovers from the injury. The extent of these changes depends on factors like the severity of the nail injury, the depth of the trauma, and the area affected. For example, damage to the base of the nail near the cuticle is more likely to cause significant changes than a crack at the tip.
Nail biting, cuticle biting, and picking at the cuticles can cause trauma to the nails. Nail biting is a main cause of acute paronychia, a type of infection in which bacteria get underneath the tissue at the side of the nail and cause swelling and irritation. Repetitive picking at the thumb nail and cuticle with the index finger can produce a line of horizontal hatch marks in the middle of the nail.
Treatment depends on the severity of the nail injury and the specific changes in nail growth. Minor trauma may heal without intervention, but keeping the area clean can promote recovery. When trauma results in significant changes or causes pain, it is recommended that you seek help from a board-certified dermatologist. Severe cases might require trimming damaged sections, draining blood from under the nail, or surgical procedures if removal is necessary. While the nail may eventually return to its original appearance, cases with profound matrix damage could need ongoing care or reconstructive approaches.

Frequently asked questions
There are several factors that influence nail growth rates, including:
- Genetics: Some individuals have a genetic predisposition for faster nail growth.
- Health and nutrition: A balanced diet rich in essential nutrients like biotin, protein, and vitamins promotes nail growth. Poor health and malnutrition can slow nail growth.
- Age: Younger individuals typically experience faster nail growth compared to older adults.
- Hormones: Hormonal fluctuations, such as during pregnancy or menopause, can influence nail growth rates.
- Blood circulation: Good blood flow and circulation promote faster nail growth.
Additionally, nails on the dominant hand tend to grow faster due to increased use and trauma, which stimulates circulation in the nail bed.
Overall, a combination of genetic, environmental, and health factors contributes to variations in nail growth rates.
Generally, fingernails grow faster than toenails. One reason for this could be that fingernails are subjected to more trauma and frequent use, stimulating faster growth. Another theory suggests that fingernails grow faster because they are closer to the heart and receive more blood circulation.
Nail biting can slow down nail growth and cause other nail problems. Biting the nails causes trauma to the nail bed, which stimulates circulation and speeds up growth. However, the overall effect is slower growth due to the constant trauma and potential for infection.
Yes, nail growth tends to be faster in warmer climates and during the summertime. This may be due to improved blood circulation in warmer temperatures, which promotes nail growth.
Taking biotin supplements can increase nail strength and growth rate, especially in individuals with brittle nails. Vitamin C, vitamin E, iron, zinc, and calcium supplements can also promote healthy nail growth if your diet is lacking in these nutrients.
