There are several factors that influence the growth rate of nails. Nails on the dominant hand tend to grow faster, as do nails on the longer fingers. The growth rate of a nail is directly related to the length of the bones in the finger. The rate of growth is also influenced by age, sex, season, exercise level, diet, and hereditary factors. Nail biting can also cause nails to grow faster, as it stimulates circulation in the nail bed. Additionally, the amount of blood flow a digit receives may play a role in nail growth, with more blood pumped to the fingers than the toes due to their proximity to the heart.

Pinky fingers are longer, so their nails grow faster
The growth rate of a nail is directly related to the length of the finger bone it grows on. The nails on your dominant hand grow faster, as do the nails on your longer fingers. This is because the longer the finger, the more protection is needed at the tip, and nails provide this protection.
The rate of growth differs by around 0.1mm, which can be noticeable from finger to finger. The nails on your dominant hand are said to grow faster because you use that hand more, increasing the risk of trauma to the nail. When trauma occurs, your body naturally sends more blood and nutrients to the area to help repair it, stimulating circulation in the nail bed underneath and encouraging growth.
Additionally, the growth of a nail is influenced by the amount of blood flow that a digit receives. As hands are closer to the heart than feet, more blood is pumped to the fingers, resulting in faster nail growth compared to toenails. This is supported by the observation that nails grow more slowly in cold weather when blood flow is restricted.
While the length of the finger seems to be a factor in nail growth speed, it is important to note that nail growth is also influenced by various other factors, including age, sex, season, exercise level, diet, and hereditary factors.

The dominant hand's nails grow faster due to increased trauma risk
The nails on your dominant hand grow faster due to the increased risk of trauma. This is because you use your dominant hand more often, which increases the likelihood of catching your nail or hitting it against something. When trauma occurs, the body sends more blood and nutrients to the area to aid in repair, stimulating circulation in the nail bed and promoting nail growth. This results in the nails on the dominant hand, including the pinky finger, growing at a faster rate compared to the non-dominant hand.
The growth rate of nails is influenced by various factors, including age, sex, season, exercise level, diet, and hereditary factors. Additionally, the length of the bones in the finger also plays a role in nail growth, with longer fingers tending to have faster-growing nails.
Biting your nails can also contribute to faster nail growth. The act of biting causes trauma to the nail, stimulating circulation in the nail bed and accelerating nail growth. However, it is important to note that regular nail clipping is a safer alternative to achieve faster-growing nails without the risks associated with nail-biting.
While it is challenging to significantly influence nail growth rate, maintaining good nail hygiene practices can help support nail health and strength. This includes proper nail care routines, such as trimming, filing, and moisturizing. Additionally, addressing any nutritional deficiencies or underlying health conditions can also impact nail growth and overall nail health.
In summary, the increased risk of trauma to the dominant hand, including the pinky finger, leads to faster nail growth due to the body's natural repair process. This, combined with factors such as finger length and nail biting, contributes to the overall growth rate of nails on the dominant hand.

Nail growth is faster in summer, with better blood flow
Fingernails and toenails grow at different rates, with toenails generally growing more slowly due to experiencing less trauma. The growth rate of fingernails varies throughout the day, peaking in the summer months. This seasonal variation may be influenced by temperature, as nails tend to grow faster in hotter countries.
Nail growth is influenced by several factors, including age, sex, exercise level, diet, genetics, and hereditary factors. Puberty is a period of rapid nail growth due to fluctuating hormone levels, which stabilise with age. The nails on the dominant hand and the longer fingers tend to grow faster, likely due to increased usage and the associated risk of trauma.
Trauma to the nail, such as biting or nail-clipping, stimulates circulation in the nail bed, promoting faster growth. This increased circulation delivers more blood and nutrients to the area, aiding in repair and growth. While there are no scientifically proven methods to accelerate nail growth, maintaining good overall health and practising proper nail hygiene can support optimal nail growth and strength.
During the summer, increased temperatures can contribute to enhanced nail growth. The warmth improves blood flow and circulation, providing essential nutrients to the nail bed and supporting nail growth. Additionally, summer activities and outdoor labour may lead to more frequent nail trauma, triggering the body's repair mechanisms and further stimulating nail growth.
In summary, nail growth is influenced by various factors, including seasonality. The combination of warmer temperatures, improved circulation, and increased trauma during the summer months contributes to faster nail growth. While the exact mechanisms are not fully understood, prioritising overall health and nail care remains essential for supporting nail growth and maintaining strong, healthy nails.
Nail Growth: What Stops It?

Nail biting stimulates circulation, speeding regrowth
Nail biting, also known as onychophagia, is a common habit that affects up to 30% of the population. While it often starts in childhood, it can also begin during adolescence or adulthood. It is typically a nervous habit and can be challenging to break.
When you bite your nails, you create trauma to the nail, which stimulates circulation in the nail bed underneath. This increased circulation speeds up nail growth. In fact, the rate of growth is three times faster for a bitten nail compared to a healthy nail.
If you want to stop biting your nails, it's important to identify your triggers. Are there certain situations or emotions that make you more likely to bite your nails? Once you know your triggers, you can work on managing them. For example, if boredom is a trigger, you could try keeping your hands busy with a stress ball or fidget toy. Keeping your nails trimmed and looking their best can also help reduce the temptation to bite them.
While nail biting can be challenging to stop, it's important to persevere as it can cause damage to your nails and the surrounding skin. It can also lead to infections as you are passing bacteria and viruses from your mouth to your fingers and face. If you are struggling to stop, there are many resources available, including cognitive behavioural therapy (CBT) and acceptance and commitment therapy (ACT).

Hereditary factors determine nail strength, thickness, and speed of growth
Several factors influence the growth rate, strength, and thickness of nails. While nail growth primarily occurs due to the multiplication of cells in the nail matrix, hereditary factors play a significant role in determining nail strength, thickness, and growth rate.
Genetics play a crucial role in determining the size and shape of nail beds. Nail growth, strength, and thickness can vary among individuals due to genetic influences. For example, some people may naturally have thicker or stronger nails that grow at a different pace compared to others.
Additionally, certain nail conditions and abnormalities can be inherited. Koilonychia, for instance, is a condition characterized by thin and fragile nails that resemble the shape of a spoon. It can be hereditary or linked to various health issues such as iron deficiency anemia, malnutrition, celiac disease, heart disease, hypothyroidism, or hemochromatosis. Onychogryphosis, which causes thickening and curvature of the nails, can also have a genetic component. Nail Patella Syndrome (NPS) is another genetic disorder that can affect nail growth and appearance, occurring in approximately one in 50,000 people.
It is worth noting that nail growth is also influenced by other factors, including age, sex, season, exercise level, diet, and blood flow to the digits. However, hereditary factors undoubtedly contribute significantly to the variation in nail strength, thickness, and growth rate observed in different individuals.
