Fingernails are made of keratin, a protein that forms the cells that make up the tissue in nails. Nails grow at an average rate of 3.47mm per month, or about a tenth of a millimetre per day. However, the rate of growth depends on various factors, including which finger the nail is on, your age, and the season. For instance, the nails on your dominant hand grow faster than the rest, as do the nails on your longer fingers. Toenails, on the other hand, grow much slower than fingernails, taking about a year to a year and a half to grow back.

What You'll Learn
Toenails take longer to grow back than fingernails
Fingernails and toenails are protective coverings for the skin on our fingers and toes. They grow continuously, albeit slowly, and losing a nail is a common occurrence. The growth rate of nails varies between individuals, and factors such as age, nutrition, and season influence their growth. Interestingly, the nails on our dominant hand tend to grow faster, and fingernails grow faster during the day and in the summer.
On average, fingernails take about four to six months to grow back, while toenails can take up to 18 months to fully regrow. This means that toenails do indeed take longer to grow back than fingernails. The difference in growth rate between fingernails and toenails is not fully understood, but it is speculated that it may be related to blood flow and nail use.
Fingers are used more frequently, resulting in increased blood flow, which likely contributes to faster fingernail growth. Toenails, on the other hand, grow at a slower rate of approximately 1.62 mm per month. Losing a toenail can be a traumatic experience, and it may take patience and time for it to heal and regrow, which can take up to a year or even longer in some cases.
Toenails are also more susceptible to certain issues, such as fungal infections, due to the warm and wet environment created inside shoes. Additionally, severe or repetitive toe-stubbing can lead to toenail detachment, and athletes who wear tight-fitting shoes are particularly prone to this issue. Ingrown toenails are another common problem, where the nail grows into the surrounding skin, causing pain and redness.
While there are no scientifically proven methods to accelerate nail growth, maintaining healthy habits can strengthen your nails and prevent breakage. For example, taking biotin supplements can enhance nail health. If you lose a nail, it's important to keep the area clean, dry, and protected to facilitate the healing process.

Nails grow faster in the summer
Fingernails grow at an average rate of 3.47mm per month or about 0.1mm per day. Toenails grow at about half to a third of this rate, at 1.62mm per month. If lost, a fingernail will take about 4 to 6 months to grow back, and a toenail will take 12 to 18 months.
There are several factors that affect the speed of nail growth. Firstly, the rate of growth depends on which finger the nail is on. The middle and fourth fingers tend to grow faster than the fifth finger (the little finger) and the thumb. The nails on your dominant hand also grow faster, as do the nails on your longer fingers. This is because you use your dominant hand more, leading to more frequent stimulation.
Nails also grow faster during the day and in the summer. This may be due to increased blood circulation in warmer months, as blood circulation slows with age. Puberty is also a time of rapid nail growth due to fluctuating hormone levels, while hormone levels tend to balance out with age.
While there are no scientifically proven methods to make nails grow faster, there are ways to increase their overall health and prevent them from breaking. For example, taking biotin supplements can help strengthen nails.

Nails on the dominant hand grow faster
Fingernails grow at an average rate of 3.47 mm per month or about a tenth of a mm per day. If you lose a fingernail, it can take up to half a year for it to grow back. Toenails, on the other hand, take about a year to a year and a half to grow back.
The rate of growth also depends on which finger the nail is on. For instance, the little finger grows slower than the other fingers. Nails on the dominant hand grow faster than the rest, as do the nails on the longer fingers. This is because you tend to use your dominant hand more often, which increases the risk of trauma, such as catching your nail on something or hitting it with an object. When trauma occurs, the body naturally sends more blood and nutrients to the area to aid in its repair.
The growth rate of nails on the dominant hand can also be influenced by other factors, such as frequent nail clipping or biting, which can stimulate circulation in the nail bed and promote faster growth. Additionally, nails tend to grow faster during the day and in the summer.
While there are no scientifically proven methods to make nails grow faster, maintaining healthy habits and proper nail care can help strengthen nails and prevent breakage. Taking biotin supplements, for example, can improve nail health and reduce breakage. Nail hardeners can also be used sparingly to strengthen nails, but prolonged use is not recommended as it can break down the nail over time.

The rate of growth also depends on the season, with nails growing faster during the summertime. This may be due to the additional absorption of Vitamin D into the body as a result of more time spent outdoors in the sun. Nails also grow faster in men than in women.
If a fingernail is lost or damaged, it can take anywhere from two to six months to grow back completely, while toenails can take up to 12 to 18 months to regrow. The new nail may have grooves or ridges and be somewhat misshapen, and this may be permanent.
While there are no scientifically proven methods to make nails grow faster, there are several ways to increase their overall health and prevent them from breaking. For example, taking vitamins and supplements such as biotin, folic acid, vitamin D, vitamin B12, iron, and magnesium can help strengthen nails.

Toenails grow at an average rate of 1.62mm per month
Toenails take longer to grow back because they are generally subjected to less trauma than fingernails. While you may stub your toe from time to time, this temporary burst of circulation doesn’t have a lasting impact on toenail growth. The rate of growth of fingernails, on the other hand, is influenced by factors such as the amount of use of a particular finger, with the nails on the dominant hand and longer fingers growing faster.
The rate of nail growth also corresponds with the amount of blood flowing through the digit. Since your hands are closer to the heart than your feet, more blood flows through your fingers than your toes, resulting in faster fingernail growth. Nails in general grow slower in cold weather when blood flow is restricted.
While there aren’t any scientifically proven methods to make nails grow faster, there are ways to increase the overall health of your nails. For example, taking biotin can help strengthen your nails and prevent them from breaking, allowing them to remain long as you grow them out.
