Fingernails and toenails are produced by the nail matrix cells that reside in the moon-shaped whitish area (lunula) at the base of the nail. Nails grow at a rate of 0.13 inches per month and require 3-6 months to completely regrow. Toenails grow more slowly, usually close to half the rate of fingernails. If the nail matrix is not damaged, the nail is typically capable of regrowth. However, if the nail matrix is damaged, the growing nail plate will contain a defect, and the nail bed can be permanently deformed.

What You'll Learn

Fingernails grow back after being removed, but toenails take longer
Fingernails and toenails are produced by the nail matrix cells that reside in the moon-shaped whitish area (lunula) at the base of the nail. The nail matrix is the "factory" where the body makes new nails. Certain injuries and illnesses can damage the nail matrix and affect how your nails look or grow. However, with the right treatment, healthy nails can grow again.
If there is no permanent damage to the nail matrix or nail bed, the nail should regrow and appear completely normal. Nails grow a little more than one-tenth of an inch per month and take 3-6 months to completely regrow. Toenails grow more slowly than fingernails, usually at close to half the rate of fingernail growth. Fingernails can regrow entirely in 3-6 months, whereas toenails can take up to 1.5 years to grow back completely.
Ageing and diseases may decrease blood flow to the hands and feet and sometimes slow the rate of nail growth. Minor damage to the nail matrix can temporarily change the nail's appearance. A severe injury could cause the nail to fall off. Once the nail matrix heals, the nail will usually start to grow again. It may take several weeks before you see the new nail appear. In cases of severe nail matrix damage, some or all of the nail may not grow back.
To prevent nail damage, it is beneficial to keep nails short. Wearing well-fitting, roomy shoes can also reduce damage to the nails.

Nail matrix damage can cause permanent nail deformation
Fingernails and toenails are formed in the nail matrix, which is located at the base of the nail. The nail matrix is responsible for creating new cells that allow nails to grow. Nails grow at a rate of around 3 to 4 millimetres a month, with toenails growing more slowly than fingernails.
The nail matrix can be damaged by injuries or certain health conditions, which can interfere with nail growth. Minor matrix damage can cause temporary changes to the nail's appearance, such as dents, horizontal ridges, spots or streaks of colour, and texture changes. More severe injuries or conditions can result in permanent nail deformation or even complete nail loss. This is because severe damage to the nail matrix can disrupt the normal growth cycle, causing the nail to grow unevenly or distortedly. Conditions like chronic thickening, uneven or irregular growth, and permanent nail loss are possible outcomes of severe matrix damage.
If the nail matrix is not damaged, the nail will typically regrow after being removed. However, it may take several weeks or months for the new nail to appear, and the rate of regrowth depends on the severity of the injury and the area affected. In some cases, the nail may never regrow if there is significant damage to the germinal matrix at the base of the nail.
Proper medical care can help heal the nail matrix and promote healthy nail growth. It is important to seek treatment for any changes in nail growth or appearance after an injury, as skilled practitioners can guide the appropriate approach to restoring nail health.
To summarise, nail matrix damage can cause permanent nail deformation, depending on the severity of the damage and the area affected. Proper care and treatment are crucial for promoting nail regrowth and minimising the risk of permanent deformation.

Proper nail clipping can prevent ingrown toenails
Nails are produced by nail matrix cells that reside in the moon-shaped whitish area (lunula) at the base of the nail. As long as the nail matrix is not damaged, the nail will typically regrow. Nails grow a little more than one-tenth of an inch per month and take 3-6 months to completely regrow. Fingernails grow faster than toenails.
Ingrown toenails are caused by the growth of the toenail into the surrounding nail fold. Symptoms include toe pain, swelling, redness, and yellow drainage. Toenail clippers are designed to handle the thicker nails on your toes, so invest in a good pair of sharp clippers with a slight curve to match the natural shape of your toenails.
- Regular nail trimming is essential for preventing ingrown toenails. Trim your nails every few weeks or as needed to maintain a proper length.
- When clipping your toenails, start from one side and work your way across in small, straight cuts. Take your time to ensure a smooth and even cut.
- Cut your nails straight across and avoid rounding the corners too much. Aim for a square shape and soften the edges with a nail file to prevent sharp corners from catching on socks or shoes.
- Avoid cutting the nails too short. Leaving a small bit of white nail at the edge helps protect the delicate skin around your nails.
- After clipping, use a nail file to smooth the corners and any rough or sharp edges. Gently file in one direction to avoid splitting your nails.
- Choose shoes that provide ample room for your toes to move freely and avoid tight or ill-fitting shoes.

Bruised nails can be treated with nail trephination
Fingernails and toenails can be prone to damage as they are situated at the back of our fingertips and toes. Bruised nails, also known as subungual hematomas, are caused by blunt or crush trauma. This results in blood collecting under the nail plate, leading to swelling, discoloration, and pain. The pain from a bruised nail is caused by the pressure exerted on the finger or toe nerves by the trapped blood.
Nail trephination is a safe and effective procedure used to treat bruised nails. It involves creating a small hole in the nail to drain the trapped blood, thereby easing the pain and reducing the pressure. The procedure is quick, simple, and painless and helps prevent weeks of unnecessary pain. It is most effective when performed within 24 to 48 hours of the injury, as the blood can clot, causing a bulk under the nail that can lead to prolonged pain.
After the trephination procedure, it is important to keep the nail clean and dry. Soaking the injured nail or swimming should be avoided until advised otherwise by a healthcare provider. In some cases, a bruised nail may indicate a more serious health condition, such as skin cancer, and seeking medical care is essential to obtain an accurate diagnosis and appropriate treatment.
While nails typically grow back after being removed, the growth rate can vary depending on the health of the individual and the condition of the nail matrix and nail bed. Fingernails grow at a rate of approximately 0.1 inches per month and can take 3-6 months to fully regrow. Toenails tend to grow more slowly. Maintaining a well-rounded diet and good general health can promote stronger nails and aid in the regrowth process.

Fungal infections can be treated with antifungal preparations
Fingernails and toenails can be affected by fungal infections, such as tinea, which spread from one person to another. Fungal infections can also be caused by fungus in the soil, air, or on your skin. Those with diabetes or compromised immune systems are at a higher risk of developing fungal infections. Symptoms of a fungal infection include white, yellow, or green smelly discharge, thickening of the nail plate, and lifting of the nail plate off the nail bed.
There are over-the-counter and prescription antifungal medicines. Treatment length varies depending on the fungal infection. Some fungal skin infections like ringworm clear up in a few weeks, while it can take months or years to clear up some fungal nail, blood, and lung infections. Antifungal medicines should be administered carefully at the appropriate dose and duration. It is important to monitor for side effects during treatment, as antifungals may cause more side effects than other antimicrobials. Some possible side effects include abdominal pain, an upset stomach, diarrhea, itchy skin, a burning sensation, or a skin rash. In rare cases, antifungal drugs may cause serious problems like liver damage or severe allergic reactions.

Frequently asked questions
Yes, fingernails grow back after being removed. The nail matrix, or nail root, is the part of the nail that generally won't be lost. However, it can be damaged, resulting in deformations of the nail as it grows back.
Fingernails grow at a rate of 0.13 inches per month, requiring 3-6 months to regrow completely. Toenails grow about half as fast.
If your fingernail has been removed, you should seek proper medical care to ensure that your nail grows back properly. In the meantime, you can care for your wound by removing any unattached remnants of the nail with a nail clipper, cleaning the nail bed with soap and water, and filing down any sharp ends.
