Fingernails grow at different rates depending on a variety of factors, including age, health, and hormone levels. On average, fingernails grow at a rate of about 0.1 millimetres per day or 3.47 millimetres per month. Toenails, on the other hand, grow much slower, at an average rate of 1.62 millimetres per month. The rate of nail growth tends to decrease with age, with some sources estimating that starting at age 25, nail growth slows by approximately 0.5% per year. Therefore, a 14-year-old individual's nail growth rate is likely to be faster than that of an adult.

What You'll Learn
Fingernails grow about 0.1mm per day
Fingernails grow approximately 0.1mm per day, or about 3.5mm per month. This amounts to roughly one-tenth of an inch (2.5mm) of growth each month. At this rate, it takes about three to six months for a fingernail to completely replace itself.
The rate of fingernail growth varies depending on several factors, including age, health, and hormone levels. For example, nail growth tends to slow down as people get older, with a noticeable decrease often occurring around the age of 20. Certain health conditions, such as thyroid disease, diabetes, and osteoporosis, can also contribute to slower nail growth. On the other hand, events like pregnancy can cause a temporary increase in nail growth due to hormonal changes.
The specific finger also influences the growth rate, with nails on the dominant hand and longer fingers growing faster. Additionally, toenails grow much slower than fingernails, with an average growth rate of 1.62mm per month.
While there are no scientifically proven methods to accelerate nail growth, maintaining good nail hygiene and nutritional habits can support overall nail health and strength. This includes practices such as regular moisturization, proper trimming, and addressing any nutritional deficiencies.
It's worth noting that nail biting and picking can lead to nail conditions that slow growth and cause damage to the nail matrix, nail bed, and surrounding skin. Therefore, it's essential to break these habits and prioritize healthy nail care practices to promote optimal nail growth.

Toenails grow slower, at 1.62mm per month
A variety of factors influence how quickly a 14-year-old's nails grow. While fingernails grow at a rate of about 0.1 millimetres per day, toenails grow much more slowly, at an average rate of 1.62 millimetres per month.
Several factors influence the rate of nail growth, including age, health, and hormone levels. Toenails, for example, tend to grow more slowly than fingernails, and this difference in growth rate may be attributed to the fact that toenails are generally subjected to less trauma than fingernails. While stubbing your toe may cause a temporary increase in circulation, this will not have a lasting impact on toenail growth.
The speed at which nails grow can also vary depending on the season, with nails growing faster in warmer weather. Additionally, the nails on your dominant hand tend to grow faster, as do the nails on your longer fingers.
It is worth noting that nail growth may slow down as you get older. Researchers estimate that by the age of 20, the growth rate of nails may decrease by approximately 0.5% per year. This could be attributed to health conditions that become more common with age, such as fungal infections, also known as onychomycosis.
Practising good nail hygiene and maintaining a nutritious, well-balanced diet can help support nail health and promote faster nail growth.

Nail growth slows with age
Fingernails grow at an average rate of 3.47 millimeters per month or about a tenth of a millimeter per day. Toenails, on the other hand, grow at an average rate of 1.62 mm per month. Several factors influence the rate of nail growth, including age, hand dominance, finger length, season, and overall health. The nails on the dominant hand and longer fingers tend to grow faster. Nail growth is also faster during the day and in the summer.
Age is a significant factor in nail growth, with growth rates slowing as individuals move past puberty. During puberty, nail growth is said to peak due to fluctuating hormone levels. As individuals age, their hormone levels stabilize, leading to a decline in nail growth rates. This decline may be attributed to the slowing of blood circulation with age.
Dr. William Bean's observations support the notion that nail growth slows with age. He noted that his left thumbnail growth rate decreased from 0.123 mm per day at age 23 to 0.095 mm per day at age 67. This decrease in growth rate over time aligns with the understanding that nail growth slows as individuals age.
In addition to slower growth, nails may undergo various changes as a person ages. These changes can include alterations in texture, thickness, color, and shape. While some changes are natural, others may indicate underlying medical conditions. For example, longitudinal melanonychia, characterized by dark stripes on the nails, can develop in darker-skinned individuals as they age. In some cases, these stripes may indicate melanoma or malignant skin cancer. Ingrown toenails, while more common in younger individuals, can cause substantial pain and walking problems in the elderly.
It is important to maintain good nail hygiene and be mindful of any significant changes in the nails. If you notice unusual symptoms or changes in nail appearance, it is advisable to consult a doctor or healthcare provider. They can help determine if the changes are due to aging or indicative of a more serious health issue.

Good nail hygiene helps nails grow
Good nail hygiene is essential for maintaining healthy nails and promoting their growth. Nails, particularly toenails, grow slowly, and certain factors can influence their growth rate, such as age, hand dominance, finger length, and overall health. While you cannot control all these factors, practicing good nail hygiene can help support nail growth and overall nail health.
One important aspect of nail hygiene is keeping nails clean and dry. Bacteria and fungi thrive in moist environments, so maintaining dry nails can prevent bacterial and fungal growth. Additionally, it is crucial to trim nails regularly and properly. For fingernails, it is recommended to cut them straight across and slightly round the tips for maximum strength. Toenails should also be cut straight across and kept short to minimize the risk of trauma and injury. Using sharp nail scissors or clippers is essential for achieving a precise and clean cut.
To smooth out jagged edges after trimming, an emery board or nail file can be used. These tools help shape the nails and remove any snags or sharp edges that could potentially lead to nail picking or biting. Nail biting is a common habit that can increase the risk of nail infections and damage the nail's structure. Instead of biting, it is advisable to clip hangnails with sanitized nail trimmers to prevent infections and maintain nail hygiene.
Moisturizing nails and cuticles is another important aspect of nail hygiene. Regular moisturizing helps keep nails healthy and strong, preventing them from becoming brittle and prone to breaking. Additionally, maintaining overall hand and nail health includes protecting nails from excessive water exposure, as it can weaken the nails, causing them to split, peel, or break. Wearing gloves while performing tasks involving water, such as cleaning or washing dishes, can help reduce water exposure and maintain nail strength.
By following these nail hygiene practices, you can support the growth and health of your nails. While the rate of nail growth may vary due to various factors, good nail hygiene can help create an optimal environment for nail growth and overall nail well-being.

Fingernails regrow in 3-6 months
Fingernails grow at a rate of about 0.1 millimetres per day, or around 3 millimetres per month. This means that it can take anywhere from 3 to 6 months for a fingernail to completely regrow if it has been lost or damaged.
The rate of growth varies depending on various factors, including age, health, and hormone levels. For instance, nail growth tends to slow down as people get older, with a noticeable decrease around the age of 20. Additionally, certain health conditions and nutritional deficiencies can impact nail growth, leading to fragile and slow-growing nails.
Puberty is another period when hormone levels fluctuate, causing nail growth to peak. During this time, nails may grow faster than usual. However, as hormone levels stabilise with age, nail growth may start to decline.
Practising good nail hygiene and maintaining a nutritious, well-balanced diet can support nail health and promote faster growth. Keeping nails trimmed and moisturised can also help prevent nail biting or picking, which can damage nails and lead to infections.
It's worth noting that the growth rate of fingernails is generally faster than that of toenails. Toenails grow at a slower rate of about 1.62 millimetres per month, taking up to a year and a half to fully regrow if lost.
