Fingernails and toenails are protective barriers that safeguard the skin underneath them. However, nails are susceptible to damage and injury, which can result in their loss or separation from the nail bed. In such cases, the question arises: how long does it take for a fingernail to regrow? On average, it takes about four to six months for a fingernail to fully regrow, with toenails taking twice as long or even up to 18 months. The rate of nail growth can vary depending on factors such as age, blood circulation, hormones, and overall health.

What You'll Learn
Fingernails grow back in 4-6 months
Fingernails are slow to grow and take time to repair themselves. On average, it takes about four to six months for a fingernail to fully regrow. The rate of growth depends on which finger the nail is on. For instance, the fingernail on your little finger grows slower than other fingernails, and the nails on your dominant hand grow faster.
Fingernails grow at an average rate of 3.47 mm per month or about a tenth of a millimeter per day. This rate of growth may decrease as you age because blood circulation slows with age. To put this in perspective, the average grain of short rice is about 5.5 mm long.
If you lose a fingernail, it can take up to six months for it to completely grow back. This is because your fingernails are generally subjected to less trauma than your toenails. Toenails take twice as long as fingernails to grow back, with a regrowth time of up to 18 months.
There are some steps you can take to promote nail regrowth and speed up the process. For example, keeping your nails trimmed and dry by wearing gloves can help, as can taking biotin supplements, which promote cell growth and help your body metabolize protein-building amino acids.

Toenails take twice as long
Fingernails can take anywhere from four to six months to regrow. Toenails, on the other hand, take twice as long, with estimates ranging from 12 to 18 months.
Toenails take longer to regrow because they grow at a slower rate than fingernails. Toenails grow at an average rate of 1.62 mm per month, or about 0.25-0.5 mm per week, whereas fingernails grow at a rate of 3.47 mm per month or about 0.5-1 mm per week. The difference in growth rate may be due to the difference in temperature affecting blood flow to the nails. Fingers receive more blood flow because they are used more often, which likely contributes to faster fingernail growth.
Toenails are also more susceptible to fungal infections, which can further slow down their regrowth. Fungus thrives in warm, wet environments, and shoes and socks provide the perfect conditions for it to grow. If you lose a toenail due to an infection, it can take up to 18 months for the fungus to grow out, in addition to the time it takes for the nail to regrow.
It's important to keep in mind that the rate of nail regrowth can vary from person to person and can be influenced by factors such as overall health, hormones, and nutrition. For example, nail growth can slow down if you're sick or malnourished, and hormones can affect regrowth, with nails growing quicker during pregnancy.
To promote healthy nail growth and prevent infections, it's recommended to keep your nails clean, dry, and protected. Additionally, biotin supplements can help nails become thicker and stronger, promoting faster growth.

Fingernails grow 0.5-1mm per week
Fingernails grow slowly, at a rate of 0.5–1 mm per week. This works out to be about one-tenth of a millimetre per day or 3.47 millimetres per month. The rate of growth depends on which finger the nail is on. For example, the little finger grows slower than other fingers, and the index finger grows the fastest. The nails on your dominant hand grow faster, as do the nails on your longer fingers.
Fingernails also grow faster during the day and during the summer. As you get older, the rate of growth may decrease because blood circulation slows with age. Your overall health impacts the growth of your nails, too. If you're sick or malnourished, your nails may grow more slowly. Hormones also play a role in the growth rate of your nails. For example, nail growth is said to peak during puberty and decline as hormone levels balance out with age. Pregnancy can also cause nails to grow faster.
If you lose a fingernail, it can take up to six months to regrow. Toenails take longer to regrow, with sources stating anywhere from six months to two years. This is because toenails are generally subjected to less trauma than fingernails, so they don't need to grow as quickly.

Toenails grow at 1.62mm per month
Fingernails and toenails grow at different rates. While fingernails grow at an average rate of 3.47 mm per month, toenails grow at a much slower rate of 1.62 mm per month. This means that toenails grow at about half the speed of fingernails.
The difference in growth rates between fingernails and toenails can be attributed to several factors. One factor is the frequency of use and trauma. Fingers are used more often than toes, resulting in greater trauma to the nail bed, which stimulates circulation and contributes to faster nail growth. Additionally, the dominant hand's fingernails tend to grow faster due to more frequent use.
Age also plays a role in nail growth rates. As people age, their blood circulation slows down, leading to slower nail growth over time. Hormones can also influence nail growth, with pregnancy resulting in rapid nail growth and lactation leading to slower nail growth. Overall health and nutrition impact nail growth as well, with sickness and malnutrition causing slower growth.
Toenails, growing at 1.62 mm per month, take a considerable amount of time to regrow if lost or damaged. It can take anywhere from six months to two years for a toenail to fully regrow, with an average of up to 18 months. This prolonged regrowth period is because toenails are generally subjected to less trauma than fingernails, resulting in slower growth and recovery.
While there are no scientifically proven methods to accelerate nail growth, maintaining overall health and nail care can help strengthen nails and prevent breakage. Taking biotin supplements, for example, has been shown to promote nail health and reduce breakage. Keeping toenails clean, dry, and protected during the regrowth process is essential, and patience is key as it can be a lengthy process.

Nail growth slows with age (and other factors)
Fingernails and toenails protect your skin, but you might lose a nail due to trauma, fungus, or other reasons. Toenails take longer to regrow than fingernails, with the latter taking anywhere from four to six months to fully regrow, and the former taking up to 18 months. The rate of regrowth can vary from person to person.
Several factors influence the speed of nail growth. One of the most significant factors is age. As you get older, your nails may change in appearance and texture. These changes can occur naturally as part of the ageing process, but they can also indicate a medical condition. One notable change is that nails tend to grow more slowly with age. For example, a 2007 study observed that between the ages of 23 and 67, the rate of nail growth on a person's left thumbnail decreased from 0.123 mm per day to 0.095 mm per day. This change in speed may be due to a decrease in blood circulation as we age.
Hormones can also affect nail growth rates. For instance, pregnancy and puberty can cause rapid nail growth, while lactation may slow it down. Overall health also plays a role in nail growth; if you're sick or malnourished, your nails may grow more slowly. Additionally, the rate of growth depends on which finger the nail is on. Nails on the dominant hand tend to grow faster because we use that hand more often. Similarly, nails on longer fingers and nails on fingers that are used more frequently tend to grow faster.
While nail growth is a gradual process that requires patience, there are some strategies to promote healthy nail growth and prevent breakage. Keeping your nails clean, dry, and protected is essential. Regular nail clipping can also help, as it is less risky than nail biting and allows nails to grow longer. Taking biotin supplements can contribute to faster nail growth by promoting cell growth and aiding in the metabolism of protein-building amino acids. However, it is always advisable to consult with a healthcare professional to determine the best course of action for your specific situation.
