Fingernails grow at an average rate of 3.47mm per month or about 0.1mm per day. However, this rate varies depending on several factors, including age, hormones, and overall health. For instance, the nails on the dominant hand tend to grow faster, and nail growth may slow down with age. To promote nail growth, it is recommended to maintain a nutritious diet, practice good nail hygiene, and take supplements like biotin. Additionally, certain nail care products and techniques can help strengthen nails and prevent breakage during the growth process.

Factors affecting nail growth rate: dominant hand, finger length, season, age, hormones, health
Fingernails grow on average about a tenth of a millimeter per day, but several factors can influence this rate of growth. These include the dominant hand, finger length, season, age, hormones, and overall health.
Dominant Hand
The nails on your dominant hand tend to grow faster because you use that hand more often. This increased use also raises your risk of nail trauma, such as catching your nail on something or hitting it with a tool. When trauma occurs, the body sends more blood and nutrients to the area to aid repair, and this can speed up nail growth.
Finger Length
The rate of nail growth also depends on which finger the nail is on. In general, the nails on longer fingers grow faster. A 2007 study found that the little finger's nail grows slower than the others.
Season
Nails grow faster during the summer and during the day.
Age
Age also affects nail growth rate. As blood circulation slows with age, nails tend to grow more slowly. For example, Dr. William Bean observed that his left thumbnail grew at a rate of 0.123 mm per day when he was 23 years old. By age 67, this rate had dropped to 0.095 mm per day.
Hormones
Hormone levels can also influence nail growth rate. Pregnancy, for instance, is associated with rapid nail growth, while lactation slows it down. Outside of pregnancy, puberty is usually when hormone levels are most imbalanced, and nail growth is said to peak during this time. Dramatic illnesses or thyroid problems can also cause hormonal changes that affect the nails.
Health
Overall health can influence nail growth. Certain conditions, such as diabetes or circulatory issues, may affect your ability to recover from common nail disorders. Additionally, nutritional deficiencies or other underlying conditions may cause unusually slow nail growth.

Promote nail growth: eat nutritious food, practice good nail hygiene, take biotin, use nail hardeners
Fingernails grow, on average, about a tenth of a millimeter per day, but factors like age, hormones, and overall health can affect this rate. For instance, your nails grow faster during the day and in the summer, and the nails on your dominant hand tend to grow faster.
To promote nail growth, it is important to eat nutritious food. Nails, like the rest of the body, require a nutritious diet to thrive. Dehydration, for example, can cause brittle, dry nails that break easily, so it is important to stay hydrated by drinking water or other liquids throughout the day. Fatty acid-rich foods encourage healthy cell development, which aids in the growth of healthy nails, so consider eating salmon, which is rich in fatty acids and vitamin B12, or lentils and beans, which are excellent vegan sources of biotin and iron. Other foods that can promote nail growth include nutrient-dense foods such as flaxseed, grapefruit, eggs, and water.
Practicing good nail hygiene is another way to promote nail growth. Keep your nails clean and dry to prevent bacteria from growing underneath them. Cut your nails straight across with sharp nail scissors or clippers, and round them slightly at the tips for maximum strength. Avoid using your nails as tools, such as opening cans, as this can cause damage. Protect your nails from too much water exposure, as this can cause them to split, peel, or break. Wear gloves when cleaning or washing dishes, and moisturize your hands afterward.
Taking biotin supplements may also help promote nail growth, as it has been linked to improved nail health. However, there is limited research to support this claim. If you decide to take biotin, there are no clear guidelines for how much to take, but it is generally safe to take every day. Just be aware that it can interfere with certain blood tests.
Using nail hardeners can also help strengthen your nails and reduce breakage, but they should be used sparingly as prolonged use can break down the nail over time. Look for products that contain ingredients like wheat protein, keratin, calcium, or biotin, and avoid those that contain formaldehyde or formalin, as these can weaken the nails over time.

Toenails grow slower than fingernails
Fingernails grow at an average rate of 3.47 mm per month or about 0.1 mm per day. This rate of growth varies depending on factors such as age, nutrition, season, gender, and overall health. For instance, the growth rate of nails slows down with age as blood circulation decreases. Hormones can also affect nail growth rates, with pregnancy and puberty being associated with increased nail growth.
Toenails, on the other hand, grow at a much slower rate of 1.62 mm per month. This difference in growth rate between fingernails and toenails is attributed to their varying levels of use and the resulting trauma to the nail bed. The nails on our fingers are used more frequently and with greater force, leading to higher trauma and a faster growth rate. Conversely, toenails are generally subjected to less trauma, resulting in slower growth.
While the growth rates of fingernails and toenails differ, it's important to note that nail growth can be influenced by additional factors such as dominant hand, time of day, and season. Nails on the dominant hand tend to grow faster, possibly due to increased usage and a higher likelihood of trauma. Similarly, fingernails grow faster during the day and in warmer seasons.
To promote healthy nail growth, it is recommended to eat a nutritious diet, practice good nail hygiene, and consider taking supplements like biotin to strengthen nails and prevent breakage. Maintaining overall health and addressing any nutritional deficiencies or underlying conditions can also contribute to optimal nail growth.
In summary, toenails grow significantly slower than fingernails due to differences in use and trauma. However, individual factors such as age, nutrition, and overall health play a role in nail growth rates as well. By understanding these factors and adopting healthy habits, individuals can support the growth and strength of their nails.

Fingernails grow at 0.1 mm/day on average, 3.47 mm/month
Fingernails grow at an average rate of 0.1 mm per day or approximately 3.47 mm per month. This rate of growth can vary depending on several factors, including age, hormone levels, overall health, and the season. For example, nails tend to grow faster during the day and in the summer. Additionally, the nails on your dominant hand typically grow faster than those on your non-dominant hand, as they are used more often and may experience more trauma or injury, stimulating nail growth.
The growth rate of your nails may also be influenced by your diet and nail care practices. Eating a nutritious diet and maintaining good nail hygiene can promote nail growth and overall nail health. This includes keeping your nails clean, regularly trimming them, and pushing back or trimming your cuticles.
Certain supplements and products can also impact nail growth. For instance, taking biotin or using nail hardeners sparingly may help strengthen your nails and prevent breakage. However, prolonged use of nail hardeners can break down the nail over time, so it is important to use them in moderation.
It is important to note that everyone's nails grow at a slightly different rate, and various environmental, behavioural, and genetic factors can influence nail growth. If you notice any changes in your nail's health or structure, it is recommended to consult a healthcare provider for evaluation.
Overall, understanding the average nail growth rate of 0.1 mm per day or 3.47 mm per month can provide insight into nail health and be useful for healthcare providers when diagnosing certain conditions.

Slow nail growth could indicate nutritional deficiencies or underlying conditions
Fingernails grow on average about 3.47 millimeters per month, or about one-tenth of a millimeter a day. However, there are several factors that can affect the rate of growth, including age, hormones, and overall health. For example, nail growth tends to slow down as people get older due to a decrease in blood circulation. Hormonal changes during pregnancy can also cause nails to grow faster, while lactation can slow down nail growth.
Slow nail growth, along with other symptoms like discolouration, could be a sign of nutritional deficiencies or underlying health conditions. Nutritional deficiencies that can affect nail growth include:
- Iron deficiency: This can cause brittle nails, spoon nails (nails that are concave horizontally or vertically), and nail peeling.
- Vitamin B deficiency: This can cause nail discolouration and ridges.
- Vitamin C deficiency: This can cause splinter hemorrhages, which appear as thin red, brown, or black lines under the nails.
- Zinc, calcium, and vitamin A, C, and E deficiencies: These can lead to nail brittleness, ridges, discolouration, and slow growth.
In addition to nutritional deficiencies, slow nail growth could also be a sign of underlying health conditions, especially in older adults. Some of these conditions include:
- Thyroid disease: This can cause fragile, slow-growing nails.
- Hypopituitarism: This condition affects the pituitary gland and can impact nail growth.
- Diabetes: Diabetes can cause a variety of nail problems, including fragile, slow-growing nails.
- Osteoporosis: This condition weakens the bones and can also affect nail growth.
- Onychomycosis: A fungal infection of the nail that is common in older people and can slow down nail growth.
If you feel like your nails are growing unusually slowly or you notice other symptoms, it is recommended to consult a doctor or healthcare provider. They can help determine the underlying cause and advise on any necessary treatments or lifestyle changes.
