Fingernails grow at an average rate of 3.47mm per month, or about 0.1mm per day. This rate varies from person to person and is influenced by factors such as age, gender, season, exercise level, diet, and genetics. For instance, younger people tend to have faster-growing nails, and nails grow more quickly in the summer than in the winter. Toenails, on the other hand, grow at a much slower rate of about 1.62mm per month. If you're interested in growing your nails, maintaining good nail hygiene and eating a nutritious diet can help support nail health and promote growth.

What You'll Learn
Fingernails grow faster in summer
Fingernails grow faster in the summer. While there are many factors that influence the rate of nail growth, such as age, gender, and hormone levels, the season also plays a role. On average, fingernails grow at a rate of about 0.1 mm per day or 3.47 mm per month. However, during the summer months, they have been observed to grow at a slightly faster rate.
The increased growth rate in the summer may be attributed to several factors. One factor could be the increase in temperature and sunlight exposure, which can affect the body's vitamin D production and circulation, both of which can influence nail growth. Additionally, summer activities and outdoor labour can lead to more trauma or injury to the nails, stimulating the body to send more nutrients to the affected area and promoting faster growth.
The nails on the dominant hand, typically the hand used for most activities, also tend to grow faster. This is because the dominant hand is more prone to nail trauma, such as catching the nail on something or hitting it with an object. The increased risk of injury triggers the body's natural repair mechanism, resulting in an increased supply of blood and nutrients to the area, which may contribute to accelerated nail growth.
While the difference in growth rate between seasons may not be significant, it is one of the many factors that can influence nail health and growth patterns. Maintaining good nail hygiene practices and overall body care can help support nail growth and keep nails strong and healthy throughout the year. This includes practices such as regular nail clipping, which is safer than nail biting, and ensuring proper nutrition to provide the body with the necessary building blocks for nail growth.
In summary, fingernails do exhibit slightly faster growth during the summer months, influenced by various factors such as temperature, sunlight exposure, and increased trauma or activity. By understanding these factors and practising good nail care habits, individuals can promote healthy nail growth and maintain strong, attractive fingernails year-round.

Toenails grow slower than fingernails
Fingernails grow at an average rate of 3.47 mm per month, or about a tenth of a millimeter per day. The rate of growth varies depending on factors such as age, gender, hormone levels, and overall health. For example, nails grow faster during the day and in the summer; they also grow more quickly on the dominant hand and on longer fingers.
Toenails, on the other hand, grow at a much slower rate of 1.62 mm per month, which is about three times slower than fingernails. If you lose a toenail, it can take up to a year and a half for it to completely grow back, whereas a fingernail would take only six months. This difference in growth rate between fingernails and toenails is due to several reasons. Firstly, toenails are generally subjected to less trauma than fingernails. While you may stub your toe, this temporary increase in circulation does not have a lasting impact on toenail growth. Additionally, age, nutrition, and season can contribute to slower nail growth, with reduced growth observed in older individuals, those with poor nutrition, and people in colder climates.

Fingernails grow faster on dominant hands
Fingernails grow at an average rate of 3.47mm per month or about a tenth of a millimeter per day. However, this rate varies from person to person and is influenced by factors such as age, hormone levels, overall health, and the season. 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 rates. Firstly, the rate of growth differs depending on which finger the nail is on. Studies have shown that the little finger's nail grows slower than other fingernails, while the rate of growth increases with the length of the finger. Secondly, the dominant hand's nails tend to grow faster than the non-dominant hand. This can be attributed to the increased likelihood of trauma and fine movements of the dominant hand, which stimulates blood and nutrient circulation, promoting faster nail growth.
The growth rate of fingernails is also influenced by age. For instance, Dr. William Bean observed that his left thumbnail's growth rate decreased from 0.123 mm per day at age 23 to 0.095 mm per day at age 67. This change in speed is likely due to the natural slowdown in blood circulation that occurs with aging. Hormone levels can also play a role, with puberty being a time of rapid nail growth due to fluctuating hormone levels. Pregnancy is another period where hormone changes can lead to rapid nail growth.
While the exact reasons are not fully understood, it is clear that fingernails, especially those of the dominant hand, tend to grow faster than toenails. Toenails are generally slower-growing, taking about three times longer to regrow than fingernails. This can be attributed to the reduced trauma and lower blood circulation in the toes compared to the fingers.
Good nail hygiene practices and overall hand care can help maintain nail health and support the nail growth process. Additionally, addressing nutritional deficiencies and underlying health conditions is essential, as these factors can impact nail growth and appearance.

Nail growth slows with age
Fingernails grow at an average rate of 3.47mm per month or about 0.1mm per day. However, this growth rate varies across individuals and is influenced by factors such as age, gender, season, exercise, diet, and genetics.
Hormonal changes can also play a role in nail growth variation. Pregnancy, for instance, can result in rapid nail growth, while lactation may decrease it. Puberty is another period of fluctuating hormones, with nail growth peaking during this time and then declining as hormone levels stabilise.
In addition to slowing nail growth, ageing can cause nails to become dull, brittle, and discoloured, with a change in curvature. These changes are primarily attributed to a decrease in blood circulation and oxygen deprivation. Ingrown toenails, lengthwise ridges, and fragmentation of fingernail tips may also occur more frequently as we age.
While many nail changes are a natural part of ageing, some may indicate underlying health issues. For example, dark stripes on the nails could signal melanoma or malignant skin cancer, while changes in texture, thickness, or shape could be indicative of other medical conditions. Therefore, it is important to consult a healthcare professional if you notice any significant or unusual changes in your nails.

Nail growth is impacted by health and hormones
Fingernails grow on average about a tenth of a millimeter per day, but this differs from person to person. The rate of growth also depends on factors such as which finger the nail is on, your age, hormone levels, and overall health. For example, the nails on your dominant hand grow faster, as do the nails on your longer fingers. Your fingernails also grow faster during the day and in the summer.
Hormones play a crucial role in regulating the different stages of nail growth, including the growth phase, resting phase, and shedding phase. High levels of androgen hormones like testosterone, which is seen in PCOS, can also make a difference in nail growth and health. For instance, those with PCOS may be more susceptible to the nail plate separating from the nail bed, or their nails developing vertical ridges or splitting vertically.
Estrogen is another hormone that can affect nail health. It is responsible for maintaining the moisture and elasticity of nails. When estrogen levels are low, nails may become dry, brittle, and prone to breakage. Lower oestrogen levels can also contribute to dull, yellow-ish fingernails. During pregnancy, oestrogen and progesterone climb to the highest levels of a woman's lifetime, often resulting in rapid nail growth.
Cortisol, the stress hormone, can also impact nail health. Chronic stress and elevated cortisol levels can weaken the immune system, making nails more susceptible to infections and fungal growth. Insulin, a hormone involved in blood sugar regulation, can also indirectly affect nail health. High insulin levels can lead to poor circulation and nerve damage, resulting in slow nail growth, discolouration, and an increased risk of nail infections.
Maintaining hormonal balance for healthy nails can be supported by managing stress, engaging in regular exercise, and getting enough sleep. If you notice any significant changes in the appearance or texture of your nails, it is advisable to consult a healthcare professional.
