Fingernails are constantly growing at a rate of about 0.1 millimetres a day, which is about 3.5 millimetres per month. This varies depending on factors such as age, hand dominance, finger length, season, and overall health. Toenails, on the other hand, grow at a much slower rate of about 1.6 millimetres per month. Losing a fingernail can take up to six months to grow back, while a toenail can take up to a year and a half.

What You'll Learn
Fingernails grow at a rate of about 0.1mm per day
Fingernails grow slowly, at a rate of about 0.1 mm per day. This equates to approximately 3.47 mm per month or about a tenth of a millimeter per day. At this rate, it can take 3 to 6 months for a fingernail to completely replace itself.
The rate of fingernail growth varies depending on several factors, including the finger on which the nail is located, the hand dominance, age, hormone levels, and overall health. For example, the nails on the dominant hand tend to grow faster, and the little finger tends to grow slower than the other fingers. Additionally, nail growth is typically faster during the day and in the summer.
Age also plays a role in nail growth rate, with growth generally peaking during puberty and declining as hormone levels balance out with age. Pregnancy can also influence nail growth rates, with increased growth during pregnancy and decreased growth during lactation.
While there are no scientifically proven methods to make nails grow faster, maintaining healthy nails can help promote growth and prevent breakage. This includes practices such as regular moisturizing, eating a nutritious and well-balanced diet, and proper nail hygiene. Certain supplements, such as biotin and collagen, have also been linked to improved nail health and growth.
It's important to note that nail growth helps maintain strong nails and replace dead portions that may break or get worn away. Toenails grow much slower than fingernails, at an average rate of 1.62 mm per month.

Toenails grow much slower than fingernails
Fingernails grow at an average rate of 3.47 mm per month or about a tenth of a millimeter per day. At this rate, it can take about 3 to 6 months for a fingernail to completely regrow. The growth rate varies depending on the finger, with the little finger growing slower than the rest, and the nails on the dominant hand growing faster.
Toenails, on the other hand, grow much slower than fingernails. They grow at an average rate of 1.62 mm per month. This is approximately half the growth rate of fingernails. If you lose a toenail, it can take up to a year and a half for it to completely grow back. That's three times as long as it takes for a fingernail to regrow.
The difference in growth rates between fingernails and toenails is likely due to differences in use and trauma to the nail bed. The nails on our dominant hand, for example, are subject to more trauma as we use that hand more. This increased trauma changes the pattern of nail growth, with greater forces on the nail bed leading to faster growth. Toenails, being subjected to less trauma, grow at a slower rate.
Age, nutrition, and season also play a role in nail growth rates. Nail growth is said to peak during puberty and then decline as hormone levels balance out with age. Slower growth has also been observed in older individuals, those who are malnourished, and those in cold climates. Additionally, nails tend to grow faster during the summertime and in warmer weather.
While there are no scientifically proven methods to make nails grow faster, there are ways to improve nail health and prevent breakage. Taking biotin, for instance, has been shown to increase overall nail health and reduce breakage.

Nails on your dominant hand grow faster
On average, fingernails grow about a tenth of an inch (2.5 millimetres) each month. This equates to around 3 to 6 months to completely replace a nail. However, this rate of growth varies depending on several factors, including which hand the nail is on, your age, hormone levels, and overall health. Interestingly, the nails on your dominant hand tend to grow faster than those on your non-dominant hand. This may be because the dominant hand is used more frequently, leading to increased blood circulation in the fingertips, which can stimulate nail growth.
Several factors contribute to the variation in nail growth rates. Firstly, the rate of growth depends on which finger the nail is on. Studies have found that the little finger's fingernail grows slower than other fingernails. Additionally, longer fingers tend to have faster-growing nails. Age also plays a role, as nail growth tends to peak during puberty and gradually declines as hormone levels stabilise with age. For example, a 2007 study observed that a left thumbnail grew at a rate of 0.123 millimetres per day at age 23, but this rate decreased to 0.095 millimetres per day by age 67.
Hormone levels can significantly impact nail growth. For instance, pregnancy can cause rapid nail growth, while lactation may decrease nail growth rate. Outside of pregnancy, puberty is typically when hormone levels are most unstable, affecting nail growth rates. Additionally, overall health and nutrition can influence nail growth. For example, vitamin D deficiency may slow nail growth, while adequate nutrition can promote healthier and potentially faster-growing nails.
While there are no scientifically proven methods to accelerate nail growth, certain practices can strengthen nails and prevent breakage, allowing them to grow longer. Taking biotin supplements, for instance, can enhance nail health. Moreover, maintaining well-moisturised nails and cuticles can help prevent breakage. Using hand lotion or moisturiser regularly can keep nails hydrated and potentially enhance growth.
It is worth noting that toenails grow much slower than fingernails, with an average growth rate of 1.62 millimetres per month. If a toenail is lost, it can take up to a year and a half to fully regrow, significantly longer than the regrowth period for fingernails. This difference in growth rate is attributed to the reduced trauma experienced by toenails compared to fingernails.

Fingernails grow faster during the day and summer
Fingernails grow at an average rate of 3.47 millimeters (mm) per month, or about a tenth of a millimeter per day. This rate of growth varies from person to person and depends on factors such as age, sex, season, exercise level, diet, and hereditary factors. Interestingly, it has been observed that fingernails grow faster during the day and in the summer.
Several factors contribute to the variation in nail growth rate. Firstly, the nails on your dominant hand tend to grow faster because you use that hand more often. This increased usage leads to a higher risk of trauma, such as catching your nail or hitting it with an object. When trauma occurs, the body responds by sending more blood and nutrients to the affected area, promoting repair and potentially accelerating nail growth.
Additionally, the rate of growth differs depending on the finger. For instance, a 2007 study found that the fingernail on the little finger tends to grow slower than the other fingernails. The specific growth rate can vary by around 0.1 mm from finger to finger, resulting in noticeable differences in length.
While there are no scientifically proven methods to make nails grow faster, maintaining healthy habits can strengthen your nails and prevent them from breaking. For example, taking biotin supplements and using nail hardeners sparingly can enhance nail health and reduce breakage. It is also beneficial to practice good nail hygiene and keep your nails and cuticles moisturized.
In summary, while fingernails typically grow at an average rate of about a tenth of a millimeter per day, various factors influence their growth rate, including hand dominance, finger length, and seasonal changes. By understanding these factors and adopting healthy nail care practices, you can promote stronger and healthier nails.

Toenails take a year and a half to grow back
Fingernails grow at a rate of about 2.5 millimetres each month, or about a tenth of a millimetre per day. At this rate, it can take about 3 to 6 months to completely replace a nail. The speed of growth depends on factors such as age, hormone levels, overall health, and the season. Nails grow faster during the summer and on the dominant hand.
Toenails, on the other hand, grow much more slowly than fingernails. They grow at an average rate of 1.62 mm per month. If you lose a toenail, it can take a considerable amount of time to regrow—anywhere from 6 months to 18 months. Toenails take longer to regrow because they are generally subjected to less trauma than fingernails. While you may stub your toe, this temporary increase in circulation won't have a lasting impact on toenail growth.
There are no scientifically proven methods to make toenails grow faster. However, there are ways to increase the overall health of your nails, such as taking biotin supplements, which promote cell growth and help the body metabolize protein-building amino acids. Keeping the wound dry and covered is also important, as the skin underneath a toenail is sensitive. It is recommended to clean and dress the nail bed daily and apply antibiotic ointment to prevent infection.
While waiting for toenails to grow back, it is important to be patient and manage any health conditions that might affect nail growth. Toenail fungus, for example, can be treated with over-the-counter or prescription products, but it may take 12 to 18 months for the fungus to grow out. In severe cases, surgical removal of the nail may be necessary, and it can take up to 18 months for the nail to fully regrow.
In summary, while fingernails can take 3 to 6 months to grow back, toenails typically take much longer, with a regrowth period of up to 18 months. This extended timeframe is due to the slower growth rate of toenails and the fact that they are less affected by trauma than fingernails. To promote healthy toenail growth, maintaining proper nail care and addressing any underlying health conditions are recommended.
