While there are several factors that influence nail growth, such as age, hormones, and overall health, it is important to note that nails do not grow overnight. On average, fingernails grow approximately 3 to 3.5 millimeters per month, or about a tenth of a millimeter per day. Toenails, on the other hand, grow at a slower rate of around 1.62 millimeters per month. If you're looking to promote nail growth, proper care and strengthening techniques can help speed up the process, but it won't happen overnight.

What You'll Learn
Fingernails grow about 0.1 mm per day
Fingernails grow approximately 0.1 mm per day, which equates to around 3 to 3.5 mm per month. This growth rate can vary depending on several factors, including age, hormone levels, overall health, and the season. For example, nails tend to grow faster during the warmer months and on the dominant hand, which is more prone to trauma.
The rate of fingernail growth also differs between individuals, with older adults experiencing slower nail growth than younger individuals. Hormones play a significant role in nail growth rates, with pregnancy resulting in faster nail growth due to increased estrogen and progesterone levels. Conversely, lactation may decrease nail growth rates. Puberty is another period of rapid nail growth due to fluctuating hormone levels.
The health of an individual can also impact nail growth. Immunocompromised individuals may experience slower nail growth, and certain chronic conditions, such as psoriasis, endocarditis, lupus, kidney disease, thyroid disease, and liver disease, can affect nail growth and appearance. Nutritional deficiencies or underlying health conditions can also lead to unusually slow nail growth or other abnormalities.
While proper nail care and hygiene practices cannot change how much nails grow overnight, they can help strengthen nails and prevent breakage, allowing them to grow longer. Trimming nails regularly and avoiding contact with allergens and irritants are recommended for maintaining healthy nails. Additionally, frequent nail clipping may slightly accelerate nail growth compared to nail biting.

Toenails grow slower, at 1.62 mm per month
Toenails grow slower than fingernails, at an average rate of 1.62mm per month, or about 0.05mm per day. This rate of growth can vary depending on several factors, including age, health, and hormone levels. For example, older adults have much lower nail growth rates than young children, and nail growth may also be affected by conditions such as nutritional deficiencies or underlying health issues.
The rate of growth for toenails can also be impacted by the time of year, with nails growing faster during the warmer months. Additionally, toenails may grow at different rates on each foot, as the nails on your dominant hand or longer toes tend to grow faster.
If you lose a toenail, it can take up to a year and a half for it to completely grow back, which is about three times longer than it would take for a fingernail to regrow. This is because toenails are generally subjected to less trauma than fingernails, and the temporary boost in circulation from stubbing your toe will not have a lasting impact on nail growth.
While there are no scientifically proven methods to make toenails grow faster, there are ways to increase their health and strength. For example, taking biotin can help strengthen nails and prevent them from breaking, allowing them to remain long as they grow. Additionally, good nail hygiene practices can help support the growth process.

Fingernails grow faster in summer and during the day
Fingernails grow at an average rate of about a tenth of a millimeter per day, which is approximately 3.47 millimeters per month. However, several factors influence their growth rate, including finger length, hand dominance, age, hormone levels, and overall health. Interestingly, fingernails grow faster during the day and in the summer.
The growth rate of fingernails varies across different fingers, with the nails on the dominant hand and longer fingers growing faster. This is attributed to increased usage, leading to more trauma and an influx of nutrients to the area, which promotes nail growth. Additionally, the little finger's nail tends to grow slower than other fingernails.
Age plays a significant role in nail growth, with nail growth rates slowing down as we advance in age. Hormone levels also influence nail growth, with pregnancy and puberty being key periods of hormonal changes that can impact nail growth rates.
External factors, such as the season, also come into play. It is suggested that sun exposure increases nail growth, which could explain why fingernails tend to grow faster during the summer months. This seasonal variation may be linked to the body's increased circulation and nutrient absorption during warmer periods.
While there are no scientifically proven methods to accelerate nail growth, maintaining good nail hygiene and overall health can support the growth process. Biotin supplements, for instance, have been shown to enhance nail health and reduce breakage. Additionally, regular nail clipping is recommended over nail biting to achieve longer nails.

Fingernails grow faster on dominant hands and longer fingers
On average, fingernails grow about a tenth of a millimeter per day, translating to roughly 3.47 millimeters per month. However, several factors influence the rate of growth, including finger length, dominant hand, age, hormone levels, and overall health.
Fingernails on the dominant hand tend to grow faster than those on the non-dominant hand. This can be attributed to more frequent use, leading to increased trauma and a higher risk of catching the nail on something or hitting it accidentally. When such trauma occurs, the body naturally increases blood flow and nutrient delivery to the affected area, promoting repair and faster nail growth.
Additionally, nails on longer fingers have been observed to grow at a quicker pace compared to those on shorter fingers. This variation in growth rate among fingers may be associated with differences in blood circulation. For instance, a 2007 study found that the little finger nail typically grows slower than nails on other fingers.
Age also plays a role in nail growth. As individuals advance in age, blood circulation slows down, leading to a decrease in nail growth rate. For example, Dr. William Bean's thumbnail growth rate reduced from 0.123 mm per day at age 23 to 0.095 mm per day at age 67.
Hormone levels can significantly influence nail growth as well. Pregnancy, puberty, and lactation are critical periods where hormone fluctuations can cause rapid nail growth or a decrease in growth rate.
While there are no scientifically proven methods to accelerate nail growth, maintaining good nail hygiene and overall health is beneficial. Nutritional deficiencies, stress, and lack of sleep can hinder nail growth, so ensuring adequate nutrition and proper self-care are essential for optimal nail health.

Hormones, age, and health impact nail growth
Fingernails grow on average about a tenth of a millimeter per day, but this rate can vary depending on factors such as hormone levels, age, and overall health. Toenails, on the other hand, grow much slower than fingernails, at an average rate of 1.62 mm per month.
Hormones play a crucial role in nail growth and health. Oestrogen, for example, helps keep water in body tissues, and lower levels of oestrogen can result in dull, yellowish fingernails. During pregnancy, when oestrogen and progesterone levels are at their highest, many women experience rapid nail growth. Conversely, during lactation, nail growth may slow down. Puberty is another period of fluctuating hormone levels, and nail growth is said to peak during this time before declining as hormone levels stabilise with age.
Age also influences nail growth and appearance. As early as age 20, the growth rate begins to slow by about 0.5% per year. This change may be attributed to a slowdown in blood circulation with age. Over time, nails may become thicker or thinner, and their texture, colour, shape, and contour may also change. Nails may become more brittle and prone to breaking, and repeated exposure to moisture or harsh chemicals can exacerbate this problem.
In addition to hormones and age, overall health can impact nail growth. Nutritional deficiencies or underlying health conditions can cause nails to grow unusually slowly or exhibit discolouration. Fungal infections, for example, are common in older individuals and can lead to nail thickening and discolouration. Certain medications or treatments may also be necessary to address these issues.
