Nails are important for protecting our fingers and toes. Unfortunately, they take a long time to grow back. Fingernails grow at an average rate of 3.47mm per month, and it takes about 4 to 6 months for a fingernail to fully regrow. Toenails grow much more slowly, at a rate of about 1.62mm per month, and it can take up to 18 months for them to regrow.

What You'll Learn
Fingernails take 4-6 months to grow back
Fingernails take around 4 to 6 months to grow back, while toenails can take twice as long, with regrowth occurring anywhere between 6 months to a year and a half. The rate of nail growth depends on various factors, including the season, finger size, and underlying health conditions. For example, nails grow faster during the summer, and the nails on the dominant hand and longer fingers tend to grow quicker. Additionally, the growth rate may be influenced by blood circulation, with higher circulation potentially contributing to faster growth.
The speed of nail regrowth can also be impacted by the reason for nail loss. Standard hygienic trimming practices typically result in faster regrowth rates than injury or nail fungus. Furthermore, certain conditions, such as fungal nail infections or skin issues like psoriasis, can affect the appearance of nails, even after they have regrown.
To promote healthy nail growth and prevent breakage, it is recommended to maintain a balanced diet rich in biotin, which can be found in foods like egg yolks, salmon, and nuts or seeds. Nail hardeners and natural nail butter containing jojoba oil can also help strengthen nails and keep them moisturized.
While waiting for nails to regrow, it is important to keep the affected area clean, dry, and protected. Trimming the nails short can help prevent accidental lifting or ripping, and dark-colored nail polish can be used to hide any bruising or discoloration during the regrowth process.

Toenails take 12-18 months to grow back
Toenails typically take longer to grow back than fingernails. While fingernails can take anywhere from four to six months to regrow, toenails can take up to 12–18 months to fully regrow. This extended timeframe is because toenails grow at a slower rate than fingernails, approximately 1.62 mm per month.
Several factors can influence the regrowth rate of toenails. Overall health plays a role, with nail growth potentially slowing if an individual is sick or malnourished. Trauma or injury can also be a factor, as an increase in blood flow to the injured area may accelerate regrowth. Additionally, nails tend to grow slower in older adults and in colder climates, while faster growth is observed in the summer and on the dominant hand.
Good hygiene practices are essential to ensure proper toenail regrowth. Toenails are susceptible to various issues, such as nail fungus and toenail infections, which can lead to detached nails or damaged nail beds. In certain cases, a podiatrist may recommend an artificial nail to protect the nail bed during the regrowth process.
To promote healthy toenail regrowth, individuals can consider taking biotin supplements, which have been associated with stronger and faster-growing nails. Maintaining overall health through proper nutrition and addressing any underlying health conditions can also positively impact nail regrowth.
It is important to note that losing a toenail can make activities like walking or jogging uncomfortable. In such cases, individuals may opt for temporary solutions like artificial toenails to improve the appearance of their nails and protect their toes until the natural toenail fully regrows.

Nails grow at 0.5-1mm per week
Fingernails and toenails grow back at different rates. On average, fingernails grow at a rate of 0.5–1 mm per week, while toenails grow at a rate of 1.62 mm per month or 0.25–0.5 mm per week. This means that it takes longer for toenails to regrow than fingernails.
The growth rate of nails can vary depending on various factors. For example, the nails on the dominant hand tend to grow faster than those on the non-dominant hand. Similarly, fingernails grow faster during the day and in the summer. The growth rate also depends on the finger; for instance, the little finger's nail grows slower than other fingernails.
Age is another factor that affects nail growth. As people age, their blood circulation slows down, resulting in slower nail growth. Hormones also play a role, with pregnancy and puberty influencing nail growth rates.
While nails usually grow back, the rate of regrowth can vary from person to person. It can take up to six months for fingernails to regrow and up to 18 months for toenails.
To promote healthy nail growth, it is recommended to maintain a balanced diet rich in biotin, such as egg yolks, salmon, and nuts. Additionally, keeping nails trimmed and practising good hygiene can help achieve stronger and healthier nails.

Toenails grow slower than fingernails
Toenails grow at a slower rate than fingernails, taking up to a year and a half to grow back completely, whereas fingernails take around six months. Toenails grow at an average rate of 1.62 mm per month, while fingernails grow at an average rate of 3.47 mm per month.
Several factors influence the speed of nail growth. One factor is age, as nails tend to grow slower in older adults due to a decrease in blood circulation. Nails also grow slower in colder climates and faster during the summer. Nails on the dominant hand tend to grow faster than nails on the non-dominant hand, as they are subject to more trauma and mechanical forces. This increase in trauma and mechanical forces leads to increased blood flow and a higher rate of nail growth.
Overall health also impacts nail growth, as it can slow down if an individual is sick or malnourished. For example, nail growth is said to peak during puberty and decline as hormone levels balance out with age. Additionally, pregnancy can result in rapid nail growth, while lactation can decrease the rate of nail growth.
While there are no scientifically proven methods to make nails grow faster, taking biotin can help improve overall nail health and reduce breakage.

Nail growth depends on the finger
The rate of nail growth depends on a variety of factors, including age, sex, season, exercise level, diet, and hereditary factors. Nails grow at a snail's pace, with fingernails taking around 4 to 6 months to regrow and toenails taking up to 18 months. On average, fingernails grow about 3 to 3.5 millimeters per month, while toenails grow at about half that rate, approximately 1.6 millimeters per month.
Interestingly, the nails on your dominant hand tend to grow faster, as do the nails on your longer fingers. This is likely because you use your dominant hand more, leading to increased blood flow and faster nail growth. The index finger nail, for example, is known to grow faster than the nail on the little finger.
Hormones can also play a role in nail growth rates. Pregnancy, puberty, and lactation can all influence how quickly your nails grow. Additionally, certain health conditions and injuries can impact the nail matrix, the part of the nail responsible for growth, and cause temporary or permanent changes in nail growth.
While there are no scientifically proven methods to accelerate nail growth, maintaining healthy habits can promote overall nail health and strengthen your nails. This includes consuming a balanced diet rich in biotin, such as egg yolks, salmon, and nuts, and staying hydrated.
