Losing a fingernail can be a painful experience, and regrowing one takes time and patience. Pinky fingernails, in particular, tend to grow slower than other fingernails. On average, it takes about four to six months for a fingernail to grow back, and up to 18 months for a toenail. During this period, it is essential to keep the nail bed clean and protected to ensure healthy regrowth.

What You'll Learn
Fingernails take 4-6 months to grow back
Fingernails take around 4 to 6 months to grow back, but this timeframe can vary. Toenails, for instance, typically take much longer, with regrowth occurring within 12 to 18 months.
The rate of fingernail growth varies depending on several factors. Firstly, the growth rate differs according to which finger the nail is on. A 2007 study found that little fingers' nails grow slower than other fingernails. Nails on the dominant hand, on the other hand, tend to grow faster, as do the nails on longer fingers. Additionally, men's nails generally grow faster than women's.
Age also plays a role in nail growth rates. As people age, their blood circulation slows down, resulting in slower nail growth. For instance, Dr William Bean observed that his left thumbnail growth rate decreased from 0.123 mm per day at age 23 to 0.095 mm per day at age 67. Hormones can also influence nail growth, with pregnancy and puberty being associated with rapid nail growth due to fluctuating hormone levels.
The health of the nail matrix, or nail root, is crucial for nail regrowth. As long as there is no permanent damage to the nail matrix or nail bed, the nail should regrow normally. Minor damage to the nail matrix may result in minor defects in the nail, while more significant damage can lead to permanent deformities. Therefore, it is important to protect the nail bed and matrix during the healing process. Keeping the nail bed dry, clean, and covered with petroleum jelly and a bandage is recommended until the nail has regrown.
While waiting for the nail to regrow, it is advised to maintain good nail hygiene by keeping nails clean and trimmed. Regular nail clipping can promote faster nail growth without the same risks associated with nail biting. Additionally, taking vitamins such as biotin, folic acid, and vitamin D can help support nail health and strengthen them, reducing the likelihood of breakage.

Toenails take 12-18 months to grow back
Toenails take significantly longer to grow back than fingernails, which typically take around 4-6 months to regrow. By contrast, it can take anywhere from 12 to 18 months for a toenail to grow back. This is because toenails grow three to four times slower than fingernails.
There are several reasons why someone might lose a toenail. Stubbing your toe, dropping something heavy on your foot, or wearing ill-fitting shoes that put repeated pressure on your toes can all cause toenail loss. Toenails can also fall off due to fungal infections, which cause nails to become thick and brittle, or other medical conditions.
While you wait for your toenail to grow back, it's important to care for your toe properly and practice good foot hygiene. Keep the nail bed clean, dry, and covered with a bandage. Change the bandage daily, and apply an antibiotic ointment to prevent infection. You should also be patient, as toenails regrow very slowly.
The rate of toenail regrowth can vary depending on individual factors such as age, health, and the extent of the damage. Younger people tend to have faster-growing nails than older adults, and good nutrition, exercise, and overall health can positively affect the speed of nail regrowth. Toenails may also grow back misshapen, especially if the nail matrix is damaged.

Nails grow faster in the summer
It takes around 4 to 6 months for a fingernail to grow back, and about 12 months for a toenail to regrow. This is because nails, which are made of keratin, grow from under the skin and push old dead cells out as new ones grow. The growth rate is about a tenth of a millimetre a day or about a tenth of an inch a month.
Several factors affect the rate of nail growth. For instance, nails grow faster in the summer than in winter, possibly due to the absorption of Vitamin D from increased sun exposure. Nails on the middle and fourth fingers tend to grow faster than those on the fifth and thumb. Massage and stimulation also seem to aid faster growth. Men's nails grow faster than women's, and toenails grow slower than fingernails.
If you lose a nail due to injury, the nail bed will take about 7 to 10 days to heal. The new nail will likely have grooves and ridges and may be misshapen. To aid the healing process, keep the nail bed dry, clean, and covered with petroleum jelly and a bandage. Change the bandage if it gets wet. Watch out for signs of infection, such as heat, redness, pain, swelling, or pus.
While you wait for your nail to grow back, ensure you get enough vitamins to promote nail health, including biotin, folic acid, and vitamin D.

Men's nails grow faster than women's
Losing a fingernail can be a painful experience, and it takes a while for a new nail to grow back. On average, it takes about 4 to 6 months for a fingernail to grow back, and toenails take even longer, anywhere from 12 to 18 months. During this time, it is important to keep the nail bed clean and covered with petroleum jelly and a bandage.
Now, an interesting fact is that men's nails tend to grow faster than women's nails. So, if you are a man, you may need to trim your nails more often than your female counterpart. Nails, in general, are a good indicator of overall health, and any discoloration or abnormal thickness could be a sign of an underlying health issue. For instance, bluish nail bed discoloration could indicate lung disease, while yellow, white, or banded nails can sometimes point to certain serious diseases.
The rate of nail growth is influenced by various factors. Firstly, fingernails grow faster in the summer than in winter, possibly due to increased Vitamin D absorption from more time spent outdoors in the sun. Secondly, the fingernails on your dominant hand tend to grow faster, and this can be attributed to more active use of that hand. Additionally, stress can affect nail growth. When the body is under stress, it diverts energy and nutrients away from nails, causing them to become weak or stop growing altogether.
While nail injuries and the subsequent regrowth process can be frustrating, it is important to remember that proper care and attention to your nails are crucial. This includes educating yourself about nail anatomy and regularly monitoring the appearance of your nails for any signs of potential health issues. By taking care of your nails and seeking medical advice when necessary, you can maintain not only their aesthetic appeal but also their health and well-being.

Nails grow slower as you age
It takes about 4 to 6 months for a fingernail to grow back, and 12 to 18 months for a toenail to grow back. Various factors affect the rate of nail growth, including which hand it is, your age, hormone levels, and overall health. Nails grow at an average rate of 3.47 mm per month, or about a tenth of a millimeter per day.
Nails undergo several changes as we age. They grow more slowly and may become brittle, dull, and prone to breaking. The growth rate slows by about 0.5% per year as early as the age of 20. For instance, a 2023 study found that Dr. William Bean's left thumbnail grew at a rate of 0.123 mm per day at age 23, and by age 67, this rate had dropped to 0.095 mm per day. This change in speed may be due to the slowing of blood circulation with age.
Nails may also become thicker or thinner with age. Conditions like psoriasis and rheumatoid arthritis can lead to thicker nails. Fungal infections, which are common in older people, can cause nail thickening and discoloration. Toenails may become particularly vulnerable as shoes provide an ideal environment for fungus to thrive. Nails may also turn yellow or become discolored, opaque, and prone to ingrown toenails.
The curve of your nails may also change over time, and they may become harder and more brittle. Repeated wetting and drying, or exposure to harsh cleaning chemicals, can further worsen these issues.
