Fingernails and toenails have a slow and steady growth rate, with several factors influencing the speed of growth. On average, fingernails grow about a tenth of a millimeter per day or around 3 millimeters per month, while toenails grow at a third of that rate, averaging 1.62 millimeters per month. The growth rate varies depending on age, hand dominance, finger length, season, and overall health. Trauma or infection can cause nail loss, and regrowth can take up to six months for fingernails and 18 months for toenails. Proper nail care, including the use of cuticle oil and collagen supplements, can promote nail health and stronger growth.

What You'll Learn
Fingernails grow faster than toenails
Fingernails and toenails have different growth rates, with fingernails growing faster. On average, fingernails grow about a tenth of a millimeter per day or 3.47 millimeters per month. Toenails, on the other hand, grow at a slower rate of 1.62 millimeters per month. This difference in growth rate is also influenced by various factors.
One theory for the discrepancy in growth rates relates to "terminal trauma." This theory suggests that the more you use a digit, the faster the corresponding nail grows. Your body assumes that your fingernails are being worn down by constant activities like scratching, typing, or other daily tasks. In contrast, your toenails are generally protected and experience less trauma, resulting in slower growth.
Another factor influencing nail growth is blood flow to the digits. The hands are closer to the heart than the feet, resulting in greater blood flow to the fingers than the toes. As a result, fingernails benefit from increased circulation and nutrients, contributing to their faster growth. This theory is further supported by the observation that nails tend to grow slower in cold weather when blood flow is typically restricted.
Additionally, the growth rate of nails can be influenced by factors such as age, hand dominance, finger length, season, and hormone levels. For example, nails on the dominant hand and longer fingers tend to grow faster. Nail growth is also said to be faster during the day and in the summer months. Hormone levels, particularly during pregnancy and puberty, can also impact nail growth rates.
While the exact reasons for the difference in growth rates between fingernails and toenails are not fully understood, it is clear that fingernails generally grow at a faster pace. This knowledge can help individuals manage their nail care routines and maintain healthy nails.

Fingernails grow at 3.47mm per month
Fingernails grow at an average rate of 3.47mm per month, or about a tenth of a millimetre per day. This rate of growth varies depending on several factors, including age, hormone levels, overall health, and the finger on which the nail is located. For instance, the little finger's fingernail grows slower than the other fingernails. Nails on the dominant hand and longer fingers also tend to grow faster.
The rate of nail growth is influenced by blood circulation, which slows down as we age. Hormones play a role as well, with pregnancy and puberty being associated with rapid nail growth. Additionally, frequent nail clipping may contribute to slightly faster nail growth.
It is important to note that nail health is crucial for optimal growth. Conditions like psoriasis, eczema, and lichen planus can affect nail health and strength, leading to changes in texture, colour, and shape. Proper nail care includes protecting them from harsh chemicals and excessive moisture, which can cause brittle nails.
In the event of nail loss or breakage, it typically takes about six months for a fingernail to grow back completely. Toenails, on the other hand, can take up to 18 months to regrow due to slower growth and less frequent trauma.

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 about one-third of the rate at which fingernails grow. If you lose a toenail, it can take up to a year and a half for it to completely grow back, which is three times as long as a fingernail would take to regrow. This is because toenails are generally subjected to less trauma than fingernails, and fingers receive more blood flow because they are used more often.
Toenail growth can be affected by age, with a decrease in growth rate of approximately 0.5% per year from the age of 25. Toenails also tend to grow slower in older adults and in colder climates. Hormones can also affect toenail growth rate, with higher levels of hormones during puberty resulting in rapid toenail growth, and lower levels during lactation resulting in decreased growth.
Toenail health can impact growth rate, with healthy toenails contributing to faster growth. Taking biotin supplements can promote toenail growth and help your body metabolize protein-building amino acids. Protecting toenails from harsh chemicals and excessive moisture can also help to prevent weakened and brittle nails, leading to increased breakage. Wearing proper gloves when handling household cleaners and avoiding immersion in water for long periods can help prevent this.
It is important to note that there are no scientifically proven methods to make toenails grow faster. However, taking care of your toenail health can help strengthen them and prevent breakage, allowing them to remain long as they grow.

Factors that affect nail growth rate
Fingernails grow at an average rate of about a tenth of a millimeter per day or 3.47 millimeters per month. Toenails, on the other hand, grow at a rate of 1.62 millimeters per month, which is about three times slower than fingernails. However, there are several factors that influence the rate of nail growth.
Age
Younger people tend to have faster-growing nails. As people age, their nails tend to slow down in growth, with a slight decline usually starting in the late 20s. This may be attributed to decreased blood flow and the development of medical conditions that affect circulation as one gets older.
Hand and Finger
The nails on your dominant hand tend to grow faster than those on your non-dominant hand. Nails on longer fingers also tend to grow faster. Additionally, a 2007 study found that the little finger's nail is the slowest-growing fingernail.
Season
Nails grow faster during the summer. During the winter, it is important to keep the skin and nails moisturized to prevent dryness, which can expose the nail bed to fungal and bacterial infections.
Hormones
Hormone levels can affect nail growth rates. For example, pregnancy tends to result in rapid nail growth, while lactation slows it down. Puberty is also a time of rapid nail growth due to fluctuating hormone levels.
Health and Medical Conditions
Overall health and certain medical conditions can impact nail growth. For example, diabetes can reduce circulation to the nails, making them weaker. Additionally, severe eczema can affect the nail matrix and temporarily interfere with nail growth.
While these factors play a role in nail growth rates, it is important to note that individual results may vary, and some factors may have a more significant influence than others depending on specific circumstances.

Tips to help nails grow faster
On average, fingernails grow about a tenth of a millimeter per day, but several factors influence this rate, including age, hormone levels, and overall health. Here are some tips to help your nails grow faster:
Maintain Nail Hygiene
Keep your nails clean and dry to prevent bacteria from growing beneath them. Use sharp manicure scissors or clippers to trim your nails straight across, then round the tips into a soft curve. Avoid cutting your nails too short or biting them, as this can lead to nail biting habits and increase the risk of breakage.
Moisturize and Hydrate
Moisturize your hands and nails with lotion, paying special attention to the base of your nails where the cuticles are located. Cuticle oil is an excellent way to hydrate your nails and promote healthy nail growth. You can use specific cuticle oils or natural oils like coconut oil, olive oil, or argan oil.
Take Care of Your Body
Eat a well-balanced diet rich in vitamins, minerals, and proteins. Include foods like eggs, lean meats, fish, beans, nuts, and leafy greens to provide essential nutrients for nail health. Ensure you're also staying hydrated by drinking enough water throughout the day.
Consider Supplements
If you feel you're not getting enough nutrients from your diet, consider taking supplements. Biotin and keratin supplements can help strengthen your nails and promote growth. Always consult with your healthcare provider before starting any new supplement regimen.
Regular Grooming and Maintenance
Regularly groom your nails to boost their strength and encourage growth. This includes trimming, filing, and moisturizing your nails. It's also essential to protect your nails from trauma and injury, as this can affect their growth.
