Nails are produced by nail matrix cells that reside in the moon-shaped whitish area at the base of the nail. If the nail matrix is not damaged, the nail typically regrows. Nails grow a little more than one-tenth of an inch per month and require 3-6 months to completely regrow. Fingernails grow faster than toenails, with the former taking 4 to 6 months to grow back and the latter taking 6 to 24 months.

What You'll Learn
Nails grow at a rate of 0.13 inches per month
Nails grow at a rate of approximately 0.13 inches per month, or a little more than one-tenth of an inch per month. This equates to around 4 to 6 months for a fingernail to grow back and anywhere from 6 months to 2 years for a toenail to regrow. The rate of regrowth can vary depending on the scenario and the health of the individual. For example, nails tend to grow slower in older adults and in colder climates.
The nail bed is the fleshy area located beneath the nail plate, composed of tightly packed cells called keratinocytes. When a nail is damaged or lost, the major concern is damage to the nail bed and adjacent structures. If there is no permanent damage to the nail matrix or nail bed, the nail should regrow normally and appear completely healthy. However, if there is damage to the nail matrix, the growing nail plate may contain defects, resulting in a permanently deformed nail.
To promote nail health and regrowth, it is important to keep the nail bed clean and dry, covering it with a bandage and applying an antibiotic ointment to prevent infection. Well-fitting, roomy shoes can also help to reduce damage to the nails. Additionally, maintaining a well-rounded diet and good general health can contribute to stronger nails.
In some cases, doctors may use artificial nail beds to aid in the regrowth process. However, if the damage is extensive, there is a possibility that the nails may not grow back at all. Overall, nail regrowth requires patience and time, and it is important to take the necessary precautions to protect and care for your nails during the healing process.
Biotin supplements are also recommended to promote cell growth and help the body metabolize protein-building amino acids, contributing to faster nail growth.

Toenails take longer to grow back than fingernails
Nails grow a little more than one-tenth of an inch per month and require 3–6 months to completely regrow. Toenails grow more slowly than fingernails, taking anywhere from 6 months to 2 years to fully regrow. This is because toenails are generally subjected to less trauma than fingernails.
Toenails are more prone to fungal infections than fingernails because fungi thrive in warm, wet environments, and shoes and socks provide the perfect conditions for fungi to grow. Toenail fungus can also be contracted by visiting a nail salon or walking barefoot in a locker room. Symptoms of toenail fungus include yellow or dark discolouration, brittleness, and thickening of the nails. Over-the-counter (OTC) and prescription products can treat nail fungus, but it can take 12 to 18 months for the fungus to grow out.
Toenails may also be more susceptible to damage from ill-fitting shoes. Stubbing your toe or dropping an item on your foot can damage your toenail. Depending on the severity of the injury, your toenail might turn black and fall off.
There are several steps you can take to care for your toenail after it has been damaged. Firstly, keep the wound dry and covered. Clean and dry your nail bed daily and cover it with a bandage, changing the bandage once a day. Apply antibiotic ointment to the damaged nail to prevent infection. If possible, keep the nail in place until it is ready to fall off, as this provides extra protection to the nail bed underneath.
Although there are no scientifically proven methods to make nails grow faster, taking biotin supplements may help promote cell growth and contribute to faster nail growth.

Nail bed injuries can cause misshapen or discoloured nails
It can take anywhere from 6 months to 2 years for a fingernail or toenail to grow back, depending on the severity of the injury and the subsequent care. Nails grow a little more than one-tenth of an inch per month and require 3-6 months to completely regrow. Toenails tend to grow more slowly than fingernails, with regrowth taking anywhere from 6 months to 2 years.
To promote nail health and prevent injuries, it is important to keep nails trimmed and filed. Wearing gloves during activities that could potentially damage nails, such as gardening or housework, is also recommended. Additionally, keeping nails moisturized is crucial, as alcohol-based hand sanitizers can dry them out, making them more brittle and susceptible to breakage.
Proper wound care is essential for nail regrowth. Keeping the wound dry and clean is of utmost importance. Covering the nail bed with petroleum jelly or antibiotic ointment and dressing it with a clean bandage can aid in the healing process and prevent infection. It is also advised to limit physical activities that may cause further trauma to the injured nail.
In some cases, minor surgical procedures on the nail bed may be necessary to improve the nail's appearance. Additionally, biotin supplements can promote cell growth and contribute to faster nail growth. It is always recommended to seek medical advice if there are any concerns or signs of infection.

Well-fitting, roomy shoes can reduce nail damage
Nails are prone to damage as they are located at the back of our fingertips and toes. Longer nails are more susceptible to damage as they can be levered off the nail bed or run into the end of an athletic shoe. Poorly fitting shoes can cause nail injury through repeated trauma. This can lead to fungal infections, which occur when fungi invade a fingernail or toenail and the skin underneath the nail (nail bed). Toenails are more commonly affected than fingernails, and symptoms include cracked, yellow, discoloured, streaked, thickened, or spotted nails.
In addition to roomy toe boxes, other features of well-fitting shoes include a rigid, snug heel counter that provides support and guidance to the heel without slipping. The heel counter should not bend when pinched or folded inward. The shoe should also have a level heel with the same density of material on the inside and outside of the foot.
By choosing well-fitting, roomy shoes, individuals can reduce the risk of nail damage and associated issues such as fungal infections and ingrown toenails. It is worth noting that nails typically take a few months to regrow, so preventing damage and supporting healthy nail growth is important.

Biotin supplements promote cell growth and help nails grow faster
Fingernails and toenails protect the soft tissue beneath them and the tips of fingers and toes. Nails grow a little more than one-tenth of an inch per month and require 3 to 6 months to completely regrow. Toenails take longer to grow back, anywhere from 6 months to 2 years.
Nails are made up of a type of cell that grows and divides rapidly. This rapid production requires a steady supply of zinc and biotin, which are essential for nail growth. Biotin, also known as vitamin B7, coenzyme R, and vitamin H, helps cells break down fat, glucose, and protein. It also helps regulate genes and how cells communicate with each other.
Biotin deficiency is rare, but consuming biotin through foods or supplements may help strengthen brittle nails and improve their growth. Studies show that taking 2.5 mg (2,500 mcg) of biotin daily may improve nail firmness, hardness, and thickness. In one study, over half of the people taking biotin had a 25% increase in nail thickness. Another study from Switzerland showed a 25% increase in nail plate thickness in patients with brittle nails who received biotin supplementation.
Biotin supplements are often marketed for strengthening nails, but there is limited scientific evidence to support these claims. While some small studies have shown positive results, more research is needed to prove that biotin helps strengthen nails and promote cell growth.
