Fingernails and toenails are made of a substance called keratin, and they grow at different rates. On average, fingernails grow about 3.47 mm per month, while toenails grow at a slower rate of 1.62 mm per month. The growth rate of nails is influenced by various factors, including age, gender, season, exercise level, diet, and hereditary factors. Nail growth is also faster on larger fingers and during the day and summer. Biting nails can increase the growth rate as it stimulates circulation in the nail bed.

What You'll Learn
Fingernails grow at an average rate of 3.47mm per month
Nail growth is said to peak during puberty and then gradually decline as hormone levels balance out with age. According to the NCBI, starting at age 25, the rate of growth decreases by approximately 0.5% per year. A 2007 study found that the little finger's nail grows slower than other fingernails, and the thumbnail grows faster. Additionally, nails grow faster on larger fingers, during the day, and in the summer.
The growth rate of fingernails is about three times faster than that of toenails, which grow at an average rate of 1.62mm per month. Toenails are generally subjected to less trauma than fingernails, which can lead to slower growth. Biting fingernails can also cause them to grow faster due to the trauma inflicted on the nail, stimulating circulation in the nail bed.
Practising good nail hygiene and maintaining overall health can help support the natural growth of fingernails.

Toenails grow much slower, at 1mm per month
Toenails grow at a much slower rate than fingernails. On average, toenails grow at a rate of 1mm per month, while fingernails grow at a rate of 3mm per month. This means that it takes a toenail a year and a half to fully grow back if lost, whereas a fingernail will take around six months.
The rate of nail growth is influenced by various factors, including age, gender, and overall health. For example, younger people tend to have faster-growing nails, and males typically have quicker nail growth than females. Additionally, nail growth is faster during the summer and during the day.
The growth rate of nails can also be affected by trauma to the nail bed. Biting your nails or stubbing your toe can cause temporary increases in circulation, which can stimulate nail growth. However, these increases in growth rate are usually minor and do not have a lasting impact.
Practicing good nail hygiene and maintaining overall health can help support nail growth. Cutting nails straight across and rounding the edges can help prevent snags and tears, while keeping toenails short can reduce the risk of injury. While there is no guaranteed way to make nails grow faster, taking care of your health and well-being can contribute to stronger and healthier nails.

Nail growth slows down with age
Fingernails and toenails are made of a substance called keratin. The root of the nail is called the matrix, which constantly produces new cells. These new cells push the old ones out, forcing them through the matrix to form the nail plate.
The average growth rate of fingernails is around 3mm per month, while toenails grow at about a third to half of that rate. However, this rate can vary depending on various factors such as age, sex, season, exercise level, diet, and hereditary factors. Starting at age 25, the rate of nail growth decreases by approximately 0.5% per year, although some sources state that this decline can begin as early as age 20.
As nails age, they may exhibit changes in growth rate, texture, thickness, shape, and color. They can become dull, brittle, and prone to breaking. Nails may also develop lengthwise ridges, which is a typical aging change. However, some nail changes can indicate more serious health issues, such as heart and lung disease, anemia, liver and kidney problems, or diabetes. Therefore, it is essential to consult a healthcare provider if you notice any significant changes in your nails.
To promote healthy nail growth, it is recommended to practice good nail hygiene and maintain strong and healthy nails. Cutting nails straight and rounding the edges can help prevent snags or tears, and keeping toenails short can reduce the risk of injury. Additionally, cuticles protect the nail root, so it is advised not to push or cut them to prevent bacterial infections.

Nail growth is faster on the dominant hand
Fingernails grow at an average rate of 3.47 mm per month or about a tenth of a millimeter per day. However, this rate can vary depending on several factors, including age, sex, season, exercise level, diet, hereditary factors, and overall health. One factor that influences nail growth is hand dominance. Interestingly, the nails on your dominant hand tend to grow faster than those on your non-dominant hand. This phenomenon may be attributed to increased usage, which leads to a higher risk of trauma, such as catching your nail on something or hitting it accidentally.
When trauma occurs, the body responds by increasing blood flow and nutrient delivery to the affected area, promoting repair and regeneration. This increased circulation and nutrient supply to the nail bed could be the reason why nails on the dominant hand seem to grow faster. It's worth noting that the growth rate also depends on the specific finger. Nails on longer fingers, such as the index and middle fingers, tend to grow faster than those on the thumb or little finger.
The rate of nail growth can also be influenced by other factors, such as the time of day and season. Nails have been observed to grow faster during the day and in the summer months. Additionally, age plays a role, with nail growth rates peaking during puberty and gradually declining as hormone levels stabilize and blood circulation slows down with age.
While the exact mechanisms behind the faster nail growth on the dominant hand are not fully understood, it is believed that the increased usage and subsequent trauma may play a significant role. Maintaining strong and healthy nails is essential, and proper nail care practices can help achieve this. This includes cutting nails straight and rounding the edges to prevent snags and tears, as well as using a nail file for maintenance.
In summary, the nails on your dominant hand do tend to grow faster, and this can be influenced by various factors such as increased usage, trauma, circulation, and nutrient delivery. While there may be individual variations, understanding these factors can provide insights into nail growth patterns and help promote overall nail health.

Biting your nails can increase the growth rate
Biting your nails is a common habit, with up to 30% of the population doing it. While it may not be done with the intention of increasing nail growth, research suggests that it may have this effect.
Nail growth rates are influenced by a variety of factors, including age, gender, medication, disease, nutritional status, injuries, temperature changes, and genetics. The nails on the dominant hand, typically the right hand for right-handed people and vice versa, tend to grow faster due to increased stimulation of the nail beds during daily activities. Additionally, nails grow faster during the summer, presumably due to increased circulation at the fingertips.
The average growth rate of fingernails is about 3 millimeters per month, which is about one-eighth of an inch. Toenails grow slower, at a rate of about 1 millimeter per month. However, biting your nails may increase this growth rate. The exact mechanism is not fully understood, but researchers theorize that the physical manipulation of the nail through biting stimulates the growth plate, leading to increased metabolic activity and faster nail formation. This trauma to the nail stimulates circulation in the nail bed, promoting faster growth.
While nail biting may not cause any direct adverse effects on the nail itself, it can have negative consequences for the surrounding areas. It can contribute to infections in the skin and nail bed, such as paronychia, and increase the likelihood of common illnesses like the cold by facilitating the transfer of bacteria from the hands to the mouth and nose. Additionally, nail biting can lead to dental problems, such as misalignment and chipped teeth, and in rare cases, it may be a sign of underlying anxiety, stress, or obsessive-compulsive disorder.
If you wish to increase nail growth, there are alternative methods that are safer and more effective than nail biting. Maintaining good nail hygiene by keeping your nails clean and trimmed is essential for nail health. Additionally, taking biotin supplements and using nail hardeners sparingly can help strengthen your nails and prevent breakage. However, prolonged use of nail hardeners should be avoided as they can break down the nail over time.
