Fingernails grow at an average rate of 3.47mm per month, or 0.1mm per day. Toenails grow much slower, at an average rate of 1.62mm per month. The growth rate of nails is influenced by various factors, including age, health, hormones, and genetics. Nails tend to grow faster during childhood and slow down as we age, with the growth rate possibly decreasing by 0.5% per year after the age of 20. Environmental factors, such as the time of year, also play a role, with nails growing faster in the summer. Additionally, nails on the dominant hand and longer fingers tend to grow faster, possibly due to increased usage and trauma. While there are no scientifically proven methods to accelerate nail growth, maintaining good nail hygiene, a nutritious diet, and overall health can help strengthen nails and prevent breakage.

What You'll Learn
Fingernails grow about 3.47mm per month
Fingernails grow approximately 3.47mm per month, or about 0.1mm per day. This rate of growth varies depending on several factors, including age, health, and hormone levels. For instance, children's nails grow faster than adults', and pregnant women experience accelerated nail growth due to increased circulation and metabolism. Additionally, the nails on your dominant hand tend to grow faster, as do the nails on your longer fingers.
Nail growth also differs among individuals, influenced by overall health and specific health conditions. For example, certain conditions like thyroid disease, hypopituitarism, diabetes, and osteoporosis can lead to fragile and slow-growing nails. Maintaining good nail hygiene and a nutritious diet can promote nail growth and overall nail health.
The rate at which nails grow can be impacted by environmental and genetic factors as well. Sun exposure is believed to increase nail growth, and nails tend to grow faster in the summer. Additionally, frequent nail clipping may contribute to slightly faster nail growth, although there are no scientifically proven methods to significantly alter nail growth rate.
Losing a fingernail can take up to six months for it to completely regrow, while a toenail can take up to a year and a half. This difference in growth rate is because toenails are generally subjected to less trauma than fingernails.

Toenails grow at 1.62mm per month
Toenails grow much more slowly than fingernails, at an average rate of 1.62mm per month. This is around half the rate of fingernail growth, which averages 3.47mm per month.
Toenails grow more slowly because they are subjected to less trauma than fingernails. Fingernails are used for many tasks and are more likely to be damaged, whereas toenails are generally protected by shoes and socks. Losing a toenail can take up to a year and a half to grow back, three times as long as a fingernail.
There are several factors that can affect the rate of nail growth, including age, hormone levels, overall health, and nutrition. For example, nails grow faster during the summertime, and the nails on your dominant hand grow faster than those on your non-dominant hand.
While there are no scientifically proven methods to make nails grow faster, there are ways to increase their health and strength. Taking biotin supplements can reduce breakage and increase overall nail health. Eating a nutritious, well-balanced diet and practising good nail hygiene can also support nail health and promote growth.

Nails grow faster in summer
On average, fingernails grow at a rate of about 3.47 millimeters per month or about a tenth of a millimeter per day. However, there are several factors that can influence the rate of nail growth, including the hand that is dominant, age, hormone levels, and overall health. Interestingly, nails tend to grow faster during the summertime.
The nails on your dominant hand typically grow faster than those on your non-dominant hand because you use it more frequently. Similarly, the nails on your longer fingers may exhibit more rapid growth. While there are no scientifically proven methods to accelerate nail growth, certain practices can enhance nail health and prevent breakage, allowing nails to attain greater lengths.
For instance, taking biotin supplements has been shown to improve nail health and reduce breakage. Additionally, while glue-on nails and toxic nail polishes may be convenient and aesthetically pleasing, they can increase the risk of nail breakage. Therefore, it is advisable to opt for non-toxic or water-based polishes when possible.
Nail hardeners can also strengthen nails and reduce breakage, but prolonged use may lead to nail deterioration over time. Formaldehyde and formalin, commonly found in nail strengtheners, should be used sparingly or avoided altogether. Maintaining good nail hygiene and practicing regular nail clipping can also promote nail health and potentially increase growth rates.
While the exact mechanism is not fully understood, it is believed that the increased sunlight exposure during summer may play a role in stimulating nail growth. This could be related to the positive effects of sunlight on vitamin D production and overall health, which in turn could influence nail growth. Additionally, warmer temperatures in the summer may increase circulation, providing more nutrients to the nails and potentially contributing to their faster growth.

Dominant hand's nails grow faster
On average, fingernails grow at a rate of about 3.47 mm per month or 0.1 mm per day. However, several factors influence this rate of growth, including age, hormone levels, overall health, and the time of year. Interestingly, nails on the dominant hand tend to grow faster than those on the non-dominant hand. This phenomenon may be attributed to more frequent use and stimulation of the dominant hand, leading to accelerated nail growth.
The dominance of one hand over the other is a well-known concept, with individuals favoring one hand for most tasks. This preference translates to more frequent use of the dominant hand in daily activities, which may contribute to faster nail growth. The increased use of the dominant hand could provide more opportunities for nail growth stimulation, resulting in longer nails.
Various online forums and discussions have users sharing their observations about their dominant hand's nail growth. Some individuals have noticed that their dominant hand's nails grow faster, requiring more frequent trimming to maintain a neat appearance. This experience aligns with the theory that the dominant hand's nails may grow more rapidly due to increased activity and stimulation.
While the exact mechanism behind this phenomenon is not fully understood, it highlights the complex interplay between hand preference and nail growth rates. It is worth noting that other factors, such as finger length, also influence nail growth. Nails on longer fingers tend to grow faster, which could be related to the distribution of nail-stimulating activities across different finger lengths.
Additionally, it is important to maintain good nail hygiene and overall hand health. Regular nail clipping is recommended over nail biting to promote healthy nail growth. Consulting a doctor is advisable if you notice unusually slow nail growth or any discoloration, as these could indicate nutritional deficiencies or underlying health conditions.

Age, health and hormones impact growth
The average rate of nail growth is around 3 mm per month, with a range of 1.8 mm to 4.5 mm considered normal. However, this rate can vary depending on various factors, including age, health, and hormones.
Age
Nail growth tends to slow down gradually as people grow older. Starting as early as the age of 20, the growth rate slows by approximately 0.5% each year. With advancing age, nails may also undergo changes in texture, thickness, shape, and colour. They can become brittle and more prone to breaking. Conditions such as psoriasis and rheumatoid arthritis can contribute to thicker nails. Older individuals are also more susceptible to fungal infections, which can lead to nail thickening and discolouration.
Health
Certain health conditions and external factors can influence nail growth and appearance. Nutritional deficiencies, long-term exposure to chemicals, and ultraviolet light can all impact nail health over time. Repeated wetting and drying of nails or exposure to harsh cleaning agents and nail cosmetics can also affect their condition. Additionally, specific medical conditions, such as psoriasis and rheumatoid arthritis, can result in thicker nails.
Hormones
Hormones play a significant role in nail growth and health. Oestrogen, for example, helps maintain hydration in body tissues, including nails. Lower levels of oestrogen can contribute to dull and yellowish fingernails. During pregnancy, when oestrogen and progesterone levels are at their highest, many women experience rapid nail growth. Hormonal imbalances, such as those involving androgen metabolites, can also impact nail health. Similar to its effects on hair and skin, an excess of androgen hormones can influence nail growth and the development of unwanted body hair.
