Long, healthy nails are often seen as a beauty standard, but achieving them naturally takes time and patience. On average, a fingernail grows about a tenth of a millimeter per day or 3.47 millimeters per month, with toenails growing at about half that rate. However, this growth rate can vary depending on various factors, including your dominant hand, finger length, age, hormone levels, overall health, and even the season, with nails growing faster in the summer. Additionally, certain habits like nail biting or picking can slow growth and lead to short, uneven nails. To promote nail growth and strength, it's important to take care of your body by maintaining a nutritious diet, practicing good nail hygiene, and considering supplements like biotin and collagen.

What You'll Learn
Fingernails grow at 3-3.5mm per month
Fingernails grow at an average rate of about 3 to 3.5 mm per month, or about a tenth of a millimeter per day. The nails on your dominant hand tend to grow faster than those on your non-dominant hand. This is because you use your dominant hand more often, and it is more prone to injuries and trauma, which stimulates nail growth as your body sends more blood and nutrients to the area to aid healing.
Additionally, your nails grow faster during the day and in the summer when the temperature is warmer. On the other hand, cold environments are associated with slower nail growth. Your fingernails also grow faster than your toenails, which grow at an average rate of 1.62 mm per month.
Several factors can affect the rate at which your fingernails grow. These include your age, hormone levels, overall health, and genetics, which play a significant role in determining the size and shape of your nail beds. Taking care of your body, eating a nutritious and well-balanced diet, and maintaining good nail hygiene can all contribute to promoting nail growth and keeping your nails healthy.
To maintain healthy nails, it is important to keep them clean and dry, trim them regularly, and avoid biting or cutting them too short. Biting your nails can harm the nails, damage the cuticles, and increase the risk of nail infections. Using artificial nails, gel manicures, or excessive nail polish can also weaken your nails, making them more prone to splitting, breakage, and infection.
If you want to enhance your nail health and promote growth, consider taking supplements such as biotin, a type of B vitamin that has been linked to healthy nails and hair. Additionally, collagen supplements and water-based nail strengtheners containing hyaluronic acid may also be beneficial in promoting nail growth and strengthening your nails.

Toenails grow slower, at 1.62mm per month
Toenails grow at a slower rate than fingernails, at an average of 1.62 mm per month. This means that it can take up to a year and a half for a toenail to completely grow back if lost, which is three times longer than it would take for a fingernail to regrow.
The rate of toenail growth is influenced by various factors, including genetics, age, hormone levels, overall health, and environmental conditions. For example, warm weather tends to be associated with increased nail growth, while cold environments may lead to slower growth. Additionally, toenails are generally subjected to less trauma than fingernails, which can impact the rate of growth.
To promote healthy toenail growth, it is important to take care of your body and maintain proper nail hygiene. This includes keeping your toenails clean and dry, trimming them regularly, and avoiding biting or clipping them too short. Biting or picking at your toenails can lead to short, uneven nails and may increase the risk of nail infections.
Supplements such as biotin and collagen have also been found to promote toenail growth and strength. Biotin, a type of B vitamin, has been linked to increased nail thickness and overall nail health. Similarly, collagen peptides have been shown to increase nail growth and decrease the frequency of broken nails.
In summary, while toenails typically grow at a slower rate of 1.62 mm per month, various factors can influence this growth rate. By maintaining proper nail hygiene and taking appropriate supplements, individuals can promote healthy and strong toenail growth.

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 can influence the rate of nail growth, including age, hormone levels, overall health, and genetics. For instance, males' nails tend to grow faster than females', except during pregnancy or puberty when higher hormone levels cause nails to grow more rapidly.
Interestingly, nails on the dominant hand typically grow faster. This may be because the dominant hand is more active and prone to damage, triggering the body to allocate more resources for repair and growth. Similarly, nails on longer fingers and those subjected to frequent trauma, like nail-biting or typing, tend to grow quicker.
While toenails generally grow slower than fingernails, they can take up to a year and a half to fully regrow if lost, compared to six months for a fingernail. This discrepancy is attributed to toenails experiencing less trauma than fingernails.
To promote nail growth and health, it's advisable to take good care of your body, address nutrient deficiencies, and protect nails from harsh chemicals and excessive moisture. While artificial nails can give the appearance of longer nails, natural nail growth requires patience, and it can take three to 18 months for nails to fully recover from biting or breakage.

Nail growth slows with age and medical conditions
On average, fingernails grow at a rate of about a tenth of a millimeter per day, or 3.47 millimeters per month. However, this rate can vary depending on various factors, including age, hormone levels, and overall health. As people age, the rate of nail growth tends to slow down. For example, a 2007 study found that the thumbnail of a 67-year-old grew at a slower rate than when they were 23 years old. This change in speed is possibly due to the slowing of blood circulation with age.
Additionally, certain medical conditions and nutrient deficiencies can impact nail growth and health. For example, iron deficiency can lead to thin, spoon-shaped nails, known as koilonychia. Psoriasis, ichthyosis, and circulation problems can result in Ram's horn nails, requiring treatment from a podiatrist or dermatologist. Changes in nail colour, such as yellowing or dark streaks, can also indicate underlying health issues. Dark streaks, for instance, could be a sign of melanoma or skin cancer, especially if they appear on a single digit.
Hormone levels also play a role in nail growth rates. Pregnancy and puberty, for instance, are associated with rapid nail growth, while lactation may slow it down. Nail growth is also said to be faster during the day and in the summer. While there are no scientifically proven methods to accelerate nail growth, maintaining overall health and proper nail care can help strengthen nails and prevent breakage.
Furthermore, nail biting or cutting nails too short can impact the appearance of nail beds, resulting in shorter-looking nails due to reduced whiteness at the tip. Fungal infections can also cause nail plates to separate from the nail bed, leading to shorter-appearing nail beds. While genetics influences nail bed size and shape, proper nail care and artificial nails can help elongate their appearance.

Nail biting and picking can damage nail beds and slow growth
On average, fingernails grow about a tenth of a millimeter per day, but this can vary depending on factors such as age, hormone levels, overall health, and even the season. The nails on your dominant hand tend to grow faster, as do the nails on your longer fingers. Toenails, on the other hand, grow much slower, at a rate of approximately 1.62 mm per month.
Now, if you're a nail biter, this habit could be hindering your nail growth. Nail biting, or onychophagia, is common, with up to 30% of the population doing it. While it may provide a sense of relief or comfort, it can have negative consequences for both your nails and your health.
For your nails, chronic nail biting can lead to damage to the nail beds and the surrounding skin. It can also result in hangnails and ragged edges, which may further tempt you to bite. Additionally, putting your fingers in your mouth increases the risk of bacterial infections, both in your nails and your body if you swallow the bitten nails.
To promote nail growth and maintain healthy nails, it's important to break the nail-biting habit. This can be challenging, but with persistence and the right strategies, it's achievable. Start by identifying the triggers that lead you to bite your nails. Common triggers include nervousness, boredom, loneliness, and hunger. Once you recognize your triggers, you can develop alternative coping mechanisms. For example, you might try squeezing a stress ball, playing with a fidget toy, or chewing gum instead. Keeping your nails trimmed and well-maintained can also reduce the temptation to bite.
If you're struggling to quit nail biting on your own, cognitive behavioral therapy (CBT) and acceptance and commitment therapy (ACT) can be effective in addressing the underlying psychological factors. These therapies can be combined with habit-reversal training to enhance their impact. By tackling the habit holistically, you'll not only improve the health and appearance of your nails but also reduce the potential health risks associated with nail biting.
