Fingernails grow at a rate of about 0.1 millimeters per day, or 3.47 millimeters per month, while toenails grow at a much slower rate of 1.62 millimeters per month. The rate of growth depends on various factors, including age, sex, season, exercise level, diet, hereditary factors, and health conditions. For example, nail growth may slow down with age due to health conditions such as fungal infections, and hormone changes during pregnancy can cause an increase in nail growth. While there is no proven way to make nails grow faster, maintaining good nail hygiene and a well-balanced diet can help support overall nail health and strength, enabling nails to grow longer and stronger.

What You'll Learn
Fingernails grow about 0.1 mm daily
Fingernails grow at an average rate of about 0.1 mm per day, translating to approximately 3.47 mm per month. This growth rate can be influenced by several factors, including age, sex, season, exercise level, diet, hereditary factors, and overall health. For instance, nail growth tends to slow down with age, and the nails on your dominant hand typically grow faster.
The rate of fingernail growth can also be impacted by hormonal changes, such as during pregnancy or puberty, when nail growth is accelerated. Certain medical conditions, such as thyroid disease, hypopituitarism, diabetes, and osteoporosis, may also influence nail growth, leading to fragile and slow-growing nails. Additionally, environmental factors, such as warm weather, have been associated with increased nail growth.
Practicing good nail hygiene and maintaining a well-balanced diet can contribute to healthier and stronger nails. A healthy diet should include protein, water, fruits, vegetables, vitamins, and minerals. Ensuring adequate iron intake is particularly important, as iron deficiency can result in brittle or dented nails. While there is no proven method to accelerate nail growth, certain remedies can strengthen nails and prevent breakage, thereby promoting overall nail health.
The growth of fingernails is a continuous process, with new cells formed in the nail matrix pushing forward as they are generated. This process occurs in the nail bed, the tissue underneath the nail, which supplies the nail with essential nutrients. Maintaining the health of the nail bed, matrix, and surrounding skin is crucial for supporting optimal nail growth and strength.

Toenails grow slower, at 1.62 mm per month
Toenails grow at a much slower rate than fingernails, which grow at about 0.1 mm per day or 3.47 mm per month. On average, toenails grow at a rate of 1.62 mm per month, which is approximately a third of the rate of fingernail growth.
The rate of nail growth is influenced by a variety of factors, including age, sex, season, exercise level, diet, and hereditary factors. For example, nail growth tends to slow down with age, and the nails on the dominant hand typically grow faster due to more frequent use and potential injuries. Hormones also play a role, with pregnancy and androgen replacement therapy associated with increased nail growth.
While there is no proven way to accelerate nail growth, maintaining good nail hygiene and overall health can support the process. A well-balanced diet, including protein, water, fruits, vegetables, vitamins, and minerals, is essential for healthy nail growth. Additionally, certain supplements like biotin and calcium can contribute to stronger nails.
It's important to note that weak or brittle nails may indicate underlying health issues such as nutritional deficiencies or conditions like diabetes and osteoporosis. If you notice unusual symptoms or slow nail growth, it is recommended to consult a doctor or dermatologist for advice.
In summary, while toenails grow slower than fingernails at 1.62 mm per month, various factors influence nail growth rates, and maintaining good health and hygiene can support optimal nail growth.

Factors like age, sex, diet, and genetics affect growth
Fingernails grow at an average rate of about 3.5mm per month or about a tenth of a millimeter per day. However, several factors influence this rate of growth, including age, sex, diet, genetics, and overall health.
Age affects nail growth, with growth rates slowing slightly over time. As early as age 20, the growth rate slows by about 0.5% per year. This change in speed may be due to a slowdown in blood circulation with age. Nails may also become thicker or thinner with age and are more prone to breaking.
Sex also plays a role in nail growth rates, with men's fingernails and toenails growing faster than women's. Additionally, male fingernails have been found to contain different trace elements than female fingernails.
Diet and nutrition are crucial factors in nail health and growth. A nutrient-rich diet is the best way to achieve strong, shiny, and healthy nails. Zinc, found in animal proteins and certain plant foods, is required for healthy nail growth. Deficiencies in vitamins, minerals, and nutrients can negatively affect nail health. For example, a lack of magnesium can lead to vertical ridges in nails, while a deficiency in vitamin B12 can cause blue or bluish-black pigmentation. Consuming a variety of vitamins and minerals through food or supplements can help improve nail health.
Genetics also influences nail growth, with variations in specific genes impacting growth rate, structure, and appearance. Mutations in the keratin gene, for instance, can lead to nail abnormalities like pachyonychia congenita, characterized by thickened nails. Understanding these genetic factors is essential for diagnosing and treating nail disorders, and targeted therapies can address genetic abnormalities.

Healthy nails are strong and long, preventing breakage
Fingernails grow at an average rate of about a tenth of a millimeter per day, or around 3.5 millimetres per month. The rate of growth depends on several factors, including age, hormones, and overall health. For instance, the nails on your dominant hand grow faster than those on your non-dominant hand, and your fingernails grow faster during the day and in the summer.
To achieve and maintain strong, long, and healthy nails, there are several steps you can take. Firstly, consider taking biotin supplements to strengthen your nails and prevent breakage. Maintaining good nail hygiene is also important. This includes keeping your nails dry and firm, as wet nails are more prone to breakage. Applying nail oil to your cuticles and hand cream to your hands can help keep your nails and the surrounding skin moisturised and healthy.
In addition to maintaining proper nail hygiene, you can prevent nail breakage by minimising activities that may cause chipping or weakening of your nails. Always use a nail polish remover instead of peeling off your nail polish, as peeling can cause layers of your nail to come off with the polish. Keeping your nails filed can also help prevent snags and jagged edges, which may otherwise lead to breakage.
Wearing nail polish can act as armour, providing a layer of protection to your nails and reducing the likelihood of breakage. Some individuals have found success with gel nails, such as Ohora Nails, which can be cured with a UV lamp and do not require glue.

Proper care and nutrition can speed up growth
On average, fingernails grow about a tenth of a millimeter per day, but this rate can vary depending on factors such as age, hormone levels, and overall health. While there may not be any scientifically proven methods to accelerate nail growth, proper care and nutrition can strengthen your nails and prevent them from breaking, allowing them to grow longer over time.
Biotin, a B vitamin, is highly recommended as a supplement to help boost nail strength. Several studies suggest that daily biotin supplementation can enhance nail strength. Biotin is most concentrated in organ meats like liver but is also found in egg yolk, dairy, yeast, salmon, avocado, sweet potato, nuts, seeds, and even cauliflower. Other B vitamins, such as vitamin B12 and folate (vitamin B9), are also crucial for nail health. Vitamin B12 contributes to red blood cell development and iron absorption, both of which are necessary for strong nails. Folate supports red blood cell formation and the development of new cells, impacting nail growth and health.
In addition to B vitamins, ensuring adequate intake of vitamin C and zinc is essential for nail health. Vitamin C is vital for collagen production, providing strength and integrity to nails. Foods rich in vitamin C include citrus fruits like oranges, strawberries, and kiwi, as well as bell peppers, green vegetables, and tomatoes. Zinc, on the other hand, is required for the growth and division of cells, including nail cells, which have a rapid growth rate. Animal proteins such as beef, poultry, fish, and eggs are excellent sources of zinc.
While supplements are available for nail health, it is generally recommended to obtain nutrients through food whenever possible. However, if you feel your nail growth is unusually slow or you notice any discoloration or other symptoms, it is advisable to consult a doctor. They can help determine if there are any underlying conditions or nutritional deficiencies affecting your nail health and provide appropriate guidance.
