Fingernails grow at an average rate of 3.47mm per month, or about a tenth of a millimeter per day. Toenails, on the other hand, grow at a much slower rate of 1.62mm per month. The rate of nail growth depends on several factors, including age, hormone levels, overall health, and even the season. For instance, nails grow faster during the day and in the summer. Additionally, the nails on the dominant hand tend to grow faster. While it is challenging to speed up nail growth, taking care of your nails by applying cuticle oil, moisturizing, and avoiding nail biting can help maintain their health and strength.

What You'll Learn
Fingernails grow at 0.1 mm per day
Fingernails grow at an average rate of 0.1 mm per day, translating to approximately 3.47 mm per month. This growth rate varies depending on several factors, including age, overall health, hormone levels, and environmental considerations. For instance, the nails on your dominant hand tend to grow faster, and nails generally grow more rapidly during the summer months and throughout the day.
The rate of nail growth is influenced by blood circulation, which slows with age. At 23 years old, Dr. William Bean observed that his left thumbnail grew at a rate of 0.123 mm per day. By age 67, this rate had decreased to 0.095 mm per day. Similarly, hormonal changes, such as during pregnancy or puberty, can cause nails to grow faster, while lactation may slow nail growth.
To promote nail health and potentially increase growth rate, it is recommended to take biotin supplements, which have been linked to improved hair and nail health. Additionally, collagen supplements and water-based nail strengtheners containing hyaluronic acid may also enhance nail growth and strength. Maintaining a nutritious and well-balanced diet and practicing good nail hygiene are other ways to support nail health and growth.
While fingernails grow at a relatively consistent rate, toenails grow much slower, at an average rate of 1.62 mm per month. If you lose a toenail, it can take up to a year and a half for it to completely regrow. Fingernails, on the other hand, typically take about six months to grow back, though this can vary depending on the reason for nail loss and the medical treatments received.

Toenails grow at 1.62 mm per month
Toenails grow at a slower rate than fingernails, at an average of 1.62 mm per month. This is approximately one-third to half the rate of fingernail growth, which averages 3.47 mm per month. The rate of toenail growth is not uniform across the population, and there are several factors that can influence how quickly your toenails grow.
Age, for example, plays a role in nail growth rate. As you get older, your nail growth may slow down due to a decrease in blood circulation. Hormones can also affect toenail growth rate. For instance, during pregnancy, nail growth may increase, while during lactation, it may decrease. Puberty is another period when hormone levels are fluctuating, and nail growth is said to peak during this time.
The health of an individual can also impact toenail growth rate. For those who are immunocompromised, paralysed, malnourished, infected, or undergoing certain drug therapies, toenail growth may be slower. Additionally, environmental factors, such as sun exposure, can influence nail growth. Toenails, being generally covered by shoes or socks, are less exposed to sunlight than fingernails. This could be a contributing factor to their slower growth rate.
While there are no scientifically proven methods to make toenails grow faster, there are ways to increase their overall health and strength. Taking supplements like biotin, a type of B vitamin, has been linked to improved nail health and thickness. Another option is to take collagen peptides, which have been shown to increase nail growth and decrease nail breakage. Practicing good nail hygiene and eating a nutritious, well-balanced diet can also support toenail health and growth.

Fingernails grow faster in summer
Fingernails usually grow at an average rate of 3.47 millimeters (mm) per month or about a tenth of a millimeter per day. However, several factors can influence the rate of growth, including the hand dominance, finger length, age, hormone levels, and overall health. Interestingly, it has been observed that fingernails grow faster during the summertime.
The nails on the dominant hand tend to grow faster because it is used more often, increasing the risk of trauma. When trauma occurs, the body sends more blood and nutrients to the affected area, promoting repair and potentially accelerating nail growth. This phenomenon may explain why some people notice accelerated nail growth in the summer, as warmer temperatures and outdoor activities can lead to increased physical activity and minor injuries.
Additionally, sun exposure has been anecdotally linked to increased nail growth. While there is limited scientific research to support this claim directly, it is known that sunlight is a vital source of vitamin D, which plays a crucial role in calcium absorption and bone health. Adequate vitamin D levels could indirectly influence nail health and growth, as calcium-rich diets have been associated with stronger nails.
The growth rate of fingernails can also vary depending on the finger. A 2007 study found that the little finger's nail grows slower than the other fingernails. Moreover, nail growth rate changes with age, with faster growth during puberty and a gradual decline as hormone levels stabilize and blood circulation slows down over time.
While there are no scientifically proven methods to significantly accelerate nail growth, maintaining overall health and proper nail care can strengthen nails and prevent breakage. This includes taking biotin supplements, ensuring adequate nutrient intake, and regularly clipping nails to maintain their shape and prevent breakage.

Nails on the dominant hand grow faster
On average, fingernails grow at a rate of about a tenth of a millimeter per day, which is approximately 3.47 millimeters per month. However, several factors influence the rate of nail growth, including age, sex, season, exercise level, diet, hereditary factors, and overall health. For instance, nail growth is said to peak during puberty and gradually decline as hormone levels stabilize with age. Similarly, toenails grow much slower than fingernails, with an average growth rate of 1.62 millimeters per month.
Interestingly, the nails on your dominant hand tend to grow faster than those on your non-dominant hand. This can be attributed to the more frequent use of the dominant hand, which increases the risk of trauma, such as catching your nail on something or hitting it. When trauma occurs, the body responds by sending more blood and nutrients to the affected area, promoting repair and potentially accelerating nail growth.
In addition to hand dominance, the length of your fingers can also influence nail growth. Nails on longer fingers tend to grow faster. This may be related to increased blood circulation in longer fingers, providing more nutrients to support nail growth.
While there are no scientifically proven methods to accelerate nail growth, certain practices can improve nail health and prevent breakage, allowing nails to grow longer. Taking biotin supplements, for instance, has been shown to enhance nail health and reduce breakage. Nail hardeners can also provide strengthening effects but should be used sparingly to avoid long-term nail damage. Maintaining good nail hygiene and avoiding glue-on nails and toxic polishes can further contribute to overall nail health.
Lastly, it's worth noting that certain conditions, such as diabetes or circulatory issues, can impact nail growth and recovery from nail disorders. If you experience any unusual symptoms or nail injuries, it is advisable to consult a doctor for personalized advice and guidance.

Nails grow slower with age
On average, fingernails grow about a tenth of a millimeter per day, or 3.47 millimeters per month. The rate of growth depends on various factors, including age, hormone levels, overall health, and the hand and finger the nail is on.
Nails tend to grow faster during the day and in the summertime. The nails on your dominant hand and longer fingers grow faster because you use them more, increasing the risk of trauma. This trauma causes an influx of blood and nutrients to the area, which may speed up nail growth.
However, as you age, your nails grow more slowly and may become dull, brittle, and opaque with a yellow tinge. They may also become harder and thicker, especially toenails, which are more prone to fungal infections due to the warm, moist environment created by shoes. The tips of the fingernails may break more easily, and lengthwise ridges may develop on both fingernails and toenails.
These changes in nail appearance and texture can be a normal part of aging, but some may indicate more serious health issues. For example, dark stripes on the nails can signal melanoma or malignant skin cancer, while other changes can be related to heart and lung disease, anemia, liver and kidney problems, or diabetes. Therefore, it is important to consult a healthcare provider if you notice significant changes in your nails as you age.
