Fingernails grow at an average rate of 3.47mm per month, or about 0.1mm per day. However, this rate varies depending on several factors, including age, genetics, and environmental conditions. For example, nails tend to grow faster on a person's dominant hand, during the summer, and when there is an injury or trauma to the nail bed. While there are no scientifically proven methods to accelerate nail growth, maintaining healthy habits such as regular clipping, applying cuticle oil, and avoiding nail-biting can help strengthen nails and prevent breakage.

What You'll Learn
Fingernails grow faster than toenails
There are several theories as to why fingernails grow faster than toenails. One theory, called the ""terminal trauma" theory, suggests that the more a digit is used, the quicker the nail grows. This is because the body assumes that fingernails are being worn down by constant use of the fingers, so it compensates by growing them at a faster rate. Toenails, on the other hand, are generally protected by shoes and are subject to less trauma, so they grow at a slower pace.
Another theory posits that the rate of nail growth is directly related to the amount of blood flowing through the digit. Since the hands are closer to the heart than the feet, more blood flows through the fingers, resulting in faster nail growth. This theory also accounts for the observation that nails tend to grow slower in cold weather when blood flow is restricted.
While the exact reason for the difference in growth rates remains unknown, it is clear that fingernails outpace toenails in terms of growth speed.
In addition to the inherent variation in growth rates between fingernails and toenails, there are other factors that can influence nail growth. For example, nails tend to grow faster during the summer and on the dominant hand, likely due to increased blood flow and usage. Additionally, nail growth rates can be influenced by age, with growth rates slowing as blood circulation decreases with age. Hormones can also play a role, with pregnancy resulting in rapid nail growth, while lactation may slow it down. Puberty is also a time when nail growth is typically accelerated.

Nails grow faster in summer
The average rate of nail growth is 3.47 millimeters (mm) per month or about a tenth of a millimeter per day. However, several factors influence the rate at which nails grow. For instance, the nails on your dominant hand tend to grow faster than those on your non-dominant hand because you use your dominant hand more. Nails on longer fingers also tend to grow faster.
Additionally, nail growth is said to be faster during the daytime and in the summer. This could be due to increased blood circulation in warmer temperatures, which may stimulate nail growth. While there are no scientifically proven methods to make nails grow faster, maintaining healthy habits and caring for your body can positively impact nail growth.
One way to improve nail health is by taking supplements like biotin, which has been shown to reduce nail breakage and enhance overall nail health. Nail hardeners can also strengthen nails, but prolonged use may weaken them over time. It is recommended to limit or avoid strengtheners containing formaldehyde or formalin. Instead, opt for nontoxic or water-based nail polishes to reduce the risk of breakage.
Frequent nail clipping can also promote nail growth without the same risks associated with nail biting. Maintaining proper nail care and adopting healthy habits can help strengthen nails, prevent breakage, and support overall nail health, allowing your nails to grow longer.
While the summer season may contribute to faster nail growth, it is important to note that individual factors such as genetics, age, and hormone levels also play a role in nail growth rates. By understanding these factors and implementing healthy habits, you can promote optimal nail growth and maintain strong and healthy nails.

The dominant hand's nails grow faster
On average, fingernails grow at a rate of 3.47 millimetres per month or 0.1 millimetres per day. However, this rate varies depending on several factors, including age, genetics, and environment. For instance, nail growth slows with age due to a decrease in blood circulation.
Interestingly, the nails on your dominant hand tend to grow faster than those on your non-dominant hand. This phenomenon is attributed to the more frequent use of the dominant hand, resulting in increased blood circulation and nutrient delivery to the area. Additionally, the dominant hand is more prone to injuries or trauma, which can further accelerate nail growth as the body directs more resources towards healing.
The rate of nail growth can also be influenced by the season, with faster growth observed during the summer months. Moreover, certain behaviours, such as frequent nail clipping or vitamin D supplementation, may contribute to faster nail growth. While there are no scientifically proven methods to accelerate nail growth, maintaining healthy habits and addressing any nutrient deficiencies can support overall nail health and strength.
The length of time required for a lost fingernail to regrow can vary, typically taking up to six months for a complete recovery. In contrast, toenails grow at a slower rate than fingernails, with a regrowth process that can take up to a year and a half. This extended duration is due to the reduced exposure of toenails to trauma and injury compared to fingernails.
While the dominant hand's nails often exhibit faster growth, individual experiences may vary. Factors such as diet, genetics, and nail care routines can influence the rate of nail growth, resulting in unique growth patterns for each person. Understanding these factors can help optimize nail health and achieve desired growth outcomes.

Nail growth slows with age
Fingernails grow at an average rate of 3.47 millimetres per month, or about a tenth of a millimetre per day. Toenails, on the other hand, grow much slower, at an average rate of 1.62 millimetres per month.
Several factors influence the speed of nail growth. Firstly, nails on the dominant hand tend to grow faster, possibly due to more frequent use. Similarly, nails on longer fingers and the dominant hand grow faster. Nails also grow faster during the summertime and during the day. Trauma or injury to the nail area can also cause it to grow faster as the body sends more blood and nutrients to support repair and healing.
However, nail growth slows down with age. By age 20, the growth rate of nails may decrease by approximately 0.5% per year. This deceleration may be attributed to the slowing of blood circulation with age. Health conditions that affect nail growth, such as fungal infections, are also more prevalent in older individuals.
As people age, their nails may undergo various changes beyond just slower growth. Nails can become dull, brittle, and discoloured, with a change in curvature. The texture, thickness, and shape of nails may also be altered, with potential medical causes that should be investigated by a healthcare provider.

Proper care can speed up nail growth
While there are no scientifically proven methods to make nails grow faster, proper nail care can increase the overall health of your nails, making them stronger and less prone to breakage. This will allow them to remain long as you grow them out.
Firstly, it is important to maintain a healthy diet, including fresh fruits and vegetables, lean sources of protein, carbohydrates, and healthy fats. Biotin, a B vitamin, is highly recommended as a supplement to boost nail strength. Oral supplementation with specific bioactive collagen peptides has also been shown to improve nail growth and reduce symptoms of brittle nails.
Secondly, regular nail grooming can help boost nail strength and reduce breakage. This includes keeping nails dry and clean, trimming them straight across, and moisturising hands and nails, especially at the base of the cuticles. Nails should also be rounded into a soft curve to prevent ingrown nails.
Thirdly, frequent nail clipping can make your nails grow a little faster. This is because nail biting can cause trauma to the nail, stimulating circulation in the nail bed. Therefore, clipping is a safer alternative to achieve longer nails.
Finally, the rate of nail growth depends on several factors, including which hand it is, your age, hormone levels, and overall health. Nails on the dominant hand tend to grow faster, possibly due to increased usage. Nail growth may also be faster during the day and in the summertime.
