The rate of nail growth varies from person to person and is influenced by factors such as age, sex, season, exercise level, diet, and genetics. On average, fingernails grow between 0.5 and 1.2 mm per week, with the dominant hand's nails and the nails on longer fingers, such as the middle finger, typically growing faster. Toenails, on the other hand, grow at a slower rate, usually taking 12 to 18 months to fully regrow. While there is no scientific proof to speed up nail growth, maintaining good nail hygiene and consuming a balanced diet can help improve overall nail health.

What You'll Learn
The rate of nail growth is connected to finger length
The rate of nail growth is influenced by a variety of factors, including age, sex, season, exercise level, diet, and hereditary factors. For example, nail growth is said to peak during puberty and decline as hormone levels balance out with age. Pregnancy can also cause a temporary increase in nail growth, followed by a decrease during lactation. In addition, nails grow faster during the day and during the summer months.
The health of the nail can also impact its growth rate. Good nail hygiene, such as keeping nails trimmed and avoiding biting them, can promote healthy nail growth. Chronic exposure to water and certain nail polishes can weaken the nail plate and cause painful splitting and peeling. Consuming foods rich in biotin, such as soybeans, nuts, avocados, mushrooms, and bananas, can provide the body with the necessary nutrients for healthy nail growth.
While the rate of nail growth is connected to finger length, it is important to note that other factors, such as wear and trauma, can also play a role. For example, the nails on the dominant hand may grow faster due to increased use and a higher risk of catching or hitting the nail. Additionally, the growth rate of toenails is slower than that of fingernails due to less frequent trauma.

Nails on the dominant hand grow faster
It is a common observation that nails on the dominant hand grow faster. While there may be multiple factors influencing nail growth, the dominant hand's nails tend to benefit from increased stimulation and use. The rate of nail growth is influenced by various factors, including age, sex, season, exercise level, diet, and hereditary factors.
The growth rate of fingernails is typically between 0.5 and 1.2 mm per week, but this varies among individuals. On average, this translates to approximately 0.1 mm of growth per day. Interestingly, the nails on the dominant hand tend to fall on the higher end of this spectrum. This can be attributed to the fact that the more a finger is used, the faster its nail tends to grow.
For instance, individuals who spend a lot of time typing may notice faster nail growth on their dominant hand. Similarly, a left-handed person may observe that the nails on their left hand grow faster due to more frequent use. In contrast, the nails on the non-dominant hand may grow at a slower pace due to reduced wear and tear.
Aside from hand dominance, other factors also influence nail growth. For example, the length of the finger itself plays a role, with longer fingers tending to support faster nail growth. Additionally, good nail hygiene practices can promote healthy nail growth and maintenance.

Trauma to nails can increase nail growth
Trauma to the nail can cause it to grow faster as the body works to repair the injury. The nail matrix, the tissue inside the cuticle where new nail cells are formed, can be injured by a blow to the nail, a crush injury, or a tear. This can result in a ridge or split developing as the nail regrows, and the outlook is generally positive. However, if the injury includes the base of the nail, some cosmetic changes may be permanent.
Nail trauma can cause various issues, including subungual hematoma (blood under the nail), nail splitting or cracking, and the nail lifting away from the nail bed. In the case of a subungual hematoma, a physician may need to evaluate the nail and drain the trapped blood. If the nail is torn or jagged, trimming it can prevent further injury. If the nail lifts off the nail bed, it can be bandaged in place, but it will not reattach, and a new nail will slowly regrow.
Proper management of nail injuries is essential to promote quick healing and prevent complications and deformities. Nail bed injuries can be challenging to reconstruct and may require grafts or microsurgical reconstruction. Scars on the nail bed can result in non-adherence, requiring the scar to be excised and the nail bed closed tension-free. Ridges can develop from regrowth after trauma, and treatment may involve removing the nail and repairing or grafting the nail bed.
While trauma to the nail can increase nail growth, other factors also influence nail growth rate. These include age, sex, season, exercise level, diet, hereditary factors, and whether the finger is dominant or longer. Additionally, toenails generally grow slower than fingernails due to less trauma and a lower rate of growth.

Nail growth is affected by age, sex, season, exercise, diet, and genetics
Nail growth is influenced by numerous factors, including age, sex, seasonality, exercise, diet, and genetics. Age plays a role in nail growth, with growth rates typically slowing down as individuals grow older. This slowdown can begin as early as age 20, with a gradual decline in growth rate over time. Additionally, nails may undergo changes in texture, thickness, colour, and shape due to ageing processes, nutritional deficiencies, or external factors like exposure to chemicals or ultraviolet light.
In terms of sex-based differences, nails on the dominant hand of an individual tend to grow faster. This could be attributed to factors such as handedness and associated activity levels. Seasonal variations also impact nail growth, with nails typically growing faster during the summertime.
Exercise and physical activity can influence nail growth through trauma and circulation. For example, nail biting or picking can stimulate circulation in the nail bed, leading to faster growth. On the other hand, medical conditions like diabetes can reduce circulation to the nails, making them weaker and potentially slowing their growth. Gentle massage can promote circulation and counteract the effects of circulatory issues.
Diet is a crucial aspect of nail health and growth. A balanced diet that includes high-quality protein, fruits, vegetables, and adequate amounts of iron, calcium, vitamins A, B12, D, and minerals like zinc and magnesium is essential for strong and healthy nails. Biotin, found in organ meats, egg yolk, dairy, salmon, avocado, and nuts, is particularly beneficial for nail growth and strength.
Genetics also plays a significant role in determining the size and shape of nail beds, and certain genetic conditions can influence nail growth and health. Overall, while some factors influencing nail growth are beyond our control, maintaining good nail hygiene, a balanced diet, and addressing any underlying health conditions can promote healthier and potentially faster-growing nails.

Pregnancy increases nail growth
While there is no direct evidence that links faster nail growth to the ring finger, there are several factors that influence nail growth. One of the most significant factors is hormone levels, which can cause variations in nail growth during pregnancy.
Pregnancy hormones can cause nails to grow longer and faster than usual. This increase in nail growth during pregnancy is due to a normal surge in hormones. While some women may enjoy this side effect of pregnancy, others may experience negative nail changes, such as brittleness, groove formation, or onycholysis, a separation of the nail from the nail bed.
During pregnancy, higher levels of estrogen prolong the growth phase of nails, resulting in thicker and longer nails. However, this increase in nail growth may also be accompanied by increased nail fragility, making nails more prone to splitting and breaking.
To maintain nail health during pregnancy, it is recommended to wear rubber gloves when doing tasks like washing dishes or cleaning, and to use a moisturizer on the hands and the skin surrounding the nails. Additionally, including biotin-rich foods in the diet, such as nuts, eggs, oatmeal, spinach, broccoli, bananas, and whole grains, can improve nail firmness and hardness.
It is important to note that these nail changes during pregnancy are temporary, and nails should return to their normal state after giving birth.
