The growth rate of nails varies from person to person and depends on several factors, including age, genetics, overall health, and nutrition. On average, fingernails grow about one-tenth of an inch (3mm) per month, or approximately 0.1mm per day. Toenails, on the other hand, grow at a slower rate of about 1.62mm per month, or roughly 0.054mm per day. It's worth noting that these numbers are only estimates, and the health and care of your nails are more important than their actual growth rate.

What You'll Learn
Nail growth varies from person to person
Health conditions can also impact nail growth, with older people being more susceptible to nail disorders. For example, fungal infections of the nail, known as onychomycosis, are more prevalent in older individuals and can hinder nail growth. Other conditions such as thyroid disease, hypopituitarism, diabetes, and osteoporosis can also cause fragile, slow-growing nails. Additionally, certain medications can affect nail growth. For instance, chemotherapy can slow down nail growth or even lead to nail loss.
Hormones play a significant role in nail growth as well. Pregnancy, for instance, is associated with increased nail growth due to hormonal changes that boost metabolism and circulation. On the other hand, hormone levels during lactation may decrease the rate of nail growth. Puberty is another period when nail growth is accelerated, but it slows down as hormone levels stabilise with age.
Nutrition is another critical factor influencing nail growth. Nutritional deficiencies can lead to slower nail growth, and certain diseases, such as malnutrition and hormonal imbalances, can make nails brittle and prone to breakage. Maintaining a nutritious and well-balanced diet is essential for promoting healthy nail growth.
Individual habits and environmental factors also come into play. For example, nail biting can damage nails and hinder their growth. Additionally, the nails on the dominant hand tend to grow faster due to more frequent use and exposure to trauma, which triggers an increased blood and nutrient supply to the area, accelerating nail growth. Interestingly, nails also tend to grow faster during the summer than in the winter, although the reason for this seasonal variation is not yet fully understood.

Fingernails grow faster than toenails
The first theory, known as "terminal trauma," suggests that the more you use a digit, the faster the nail grows. This is because the body assumes that fingernails are being worn down by constant use, so it compensates by growing them faster. In contrast, toenails, tucked away in shoes, are subject to less trauma and, therefore, grow at a slower pace.
The second theory proposes a direct correlation between nail growth rate and blood flow to the digit. Since the hands are closer to the heart than the feet, there is increased blood flow to the fingers, promoting longer fingernails. This theory also accounts for slower nail growth in cold weather when blood flow is typically restricted.
While the exact reasons for the disparity in growth rates remain unknown, it is clear that fingernails outpace toenails in terms of growth. Additionally, it is worth noting that nail growth rates can vary from person to person, influenced by factors such as age, hormones, overall health, and nutrition. Maintaining a healthy lifestyle and a nutritious diet can contribute to optimal nail growth.
Furthermore, it has been observed that nails on the dominant hand tend to grow faster due to increased usage, leading to a higher risk of trauma. Interestingly, nail growth rates have been found to increase during the summertime, possibly due to improved blood circulation. While there are no scientifically proven methods to accelerate nail growth, certain vitamins and supplements, such as biotin, have been linked to enhanced nail health and strength.

Nails on the dominant hand grow faster
On average, fingernails grow about 0.1 to 0.15 millimetres per day or around 2 to 3 millimetres per month. However, this growth rate varies from person to person and depends on factors such as age, sex, genetics, overall health, exercise level, diet, and nutrition. For example, nail growth tends to slow down with age, with conditions like thyroid disease, diabetes, and osteoporosis potentially causing fragile, slow-growing nails. Hormones can also play a role, with pregnancy and puberty leading to rapid nail growth, while lactation and the balancing out of hormones with age can slow it down.
While there may seem to be no clear pattern to nail growth, certain factors can influence it. Interestingly, one of these factors is hand dominance. Nails on the dominant hand are said to grow faster, and this can be attributed to increased usage. Using your dominant hand more frequently increases the risk of trauma, such as catching your nail or hitting it accidentally. In response to such trauma, the body naturally sends more blood and nutrients to the affected area to aid in repair, and this increased nutrient supply may result in accelerated nail growth.
Several individuals have shared their experiences with faster nail growth on their dominant hand. Some right-handed people have observed that their left hand's nails grow faster, while a left-handed individual noticed the opposite trend. This variation in growth rate between the dominant and non-dominant hands may be more noticeable for those who perform most tasks with their dominant hand, leading to a more significant difference in growth rates.
While there are no scientifically proven methods to make nails grow faster, maintaining a healthy lifestyle and a nutritious diet can promote overall nail health and support their growth. Caring for your nails through proper hygiene, including regularly washing and drying your hands and nails, is also essential to prevent brittleness and breakage. Additionally, protecting your nails while performing tasks that may cause trauma, such as using protective gloves when cleaning with harsh chemicals, can help maintain their health and appearance.

Nail growth slows with age
On average, nails grow about 0.1 to 0.15 millimetres per day, or 2 to 3 millimetres per month. However, this rate varies from person to person and depends on several factors, including age, genetics, overall health, and nutrition. As you get older, your nail growth may slow down. Researchers estimate that by age 20, the growth rate of your nails may slow by as much as 0.5% per year. One reason for this is that health conditions impacting nail growth become more common as we age. For example, fungal infections of the nail, known as onychomycosis, represent about half of all nail disorders and are more likely to occur in older people.
Hormones can also play a role in nail growth. Hormonal changes during pregnancy, for instance, can cause nails to grow faster, while hormone levels tend to stabilize with age, leading to a decline in nail growth. Additionally, certain medical conditions can affect nail growth. Research has shown that conditions like thyroid disease, hypopituitarism, diabetes, and osteoporosis can cause fragile, slow-growing nails.
The curve of your nails may also change over time. A significant shape change, such as very rounded nails, is known as clubbing and can indicate long-term oxygen deprivation. It is often associated with various diseases, including kidney, liver, and endocrine disorders, and should be evaluated by a healthcare provider. As we age, nails may also turn yellow or become discoloured, taking on a greyish, pale, or opaque appearance.
While nail growth slows with age, it is important to maintain healthy nail care practices. This includes keeping your nails clean and dry, trimming them regularly, and avoiding biting them or cutting them too short. A nutritious, well-balanced diet and good nail hygiene can also support nail health and promote growth.

Nutritional deficiencies and health conditions can slow nail growth
On average, fingernails grow about a tenth of a millimeter per day, while toenails grow at an average rate of 1.62 mm per month. However, nutritional deficiencies and health conditions can cause nails to grow slower than these average rates.
Nutritional Deficiencies
Nails are often considered a mirror of one's nutritional status. Almost any nutritional deficiency can produce changes in the nail plate, and some can also affect the nail bed. For example, iron deficiency anemia can lead to lower iron content in the nails. Similarly, vitamin C deficiency can cause splinter hemorrhages under the nails. Vitamin D, calcium, amino acids, and gelatin deficiencies can also contribute to brittle nails. Malnutrition, such as in Kwashiorkor and Marasmus, can result in nail abnormalities like soft and thin nails, fissured nails, and impaired nail growth.
Health Conditions
Certain health conditions can also impact nail growth. For instance, diabetes and circulatory issues may affect your ability to recover from common nail disorders. Curved nails, known as "clubbing," can be a harmless trait or an indication of underlying diseases, such as in the lungs or heart. Deep grooves across the width of the nail, known as "Beau lines," can indicate that something slowed or temporarily stopped nail growth. This could be due to a fever, injury, chemotherapy, or significant stress. Additionally, melanoma, the most severe type of skin cancer, can sometimes present as a new or changing dark streak under the nail.
If you notice unusual symptoms or slow nail growth, it is recommended to consult a healthcare professional. They can help determine the underlying cause and advise appropriate next steps.
