Losing a fingernail or toenail can be painful and unsightly, but fortunately, nails have good regeneration capacity. The nail matrix, where new nails form, is rarely permanently damaged, and with proper care, a healthy nail should grow back. The time it takes for a nail to grow back depends on various factors, including the reason for the nail loss, age, and overall health.

What You'll Learn

Nails usually grow back, but it may take months
Nails have a good regeneration capacity, but they grow slowly. The nail matrix is where your fingernails or toenails form. Injuries and some health conditions can damage your nail matrix, but with the right treatment, you can often see healthy nails grow again. Even if your nail falls off, it usually grows back with proper medical care. It is rare for your nail matrix to be permanently damaged, preventing your nail from growing back.
Fungal infections, such as tinea, are spread from person to person and can affect the fingernails or toenails. 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. Surgical removal of a nail might be necessary in severe cases. After medical removal, it can take up to 18 months for a toenail to fully regrow and about 4 to 6 months for a fingernail. Toenails grow more slowly, usually at close to half the rate of fingernails.
If there is no evidence of tears or lacerations to the matrix or the nail bed, simply removing any unattached remnants of the nail with a nail clipper and cleaning the nail bed with a soapy washcloth and water to remove foreign material and blood is all that is necessary. Any remaining sharp ends should be filed smoothly so that they will not catch on clothing or socks. The uncovered nail bed can be covered with petroleum jelly or neomycin ointment and dressed with a clean bandage.
After a nail removal procedure, it is important to avoid putting any pressure on the affected foot or hand for the next 24 hours. Then, slowly resume regular activities. Elevate the affected foot while resting for the first 24 to 48 hours after the procedure, which helps decrease pain.

Protect the nail bed and keep it dry to prevent infection
Protecting the nail bed and keeping it dry is crucial to prevent infection and promote healing. After a nail removal procedure, it is important to keep the wound clean and dry. Gently wash the wound with unscented soap and water, and ensure it is thoroughly dried.
It is recommended to cover the nail bed with a thin layer of petroleum jelly, such as Vaseline, to keep the area moist and protected. This will also help prevent infection by acting as a barrier against germs. Apply a fresh coat of petroleum jelly each time you wash or whenever the bandage gets wet.
Cover the nail bed with a non-stick, clean bandage or adhesive tape to protect it from external factors and potential sources of infection. Change the bandage regularly, especially if it gets wet, to maintain a dry environment for the nail bed.
Additionally, keep your hands or feet elevated whenever possible during the initial healing phase. This helps reduce blood flow to the area, minimising the risk of infection and promoting faster healing.

Take biotin supplements to promote cell growth
While nails have a good regeneration capacity, they grow slowly. Fingernails may grow one-tenth of a millimeter each day, so completely removed fingernails usually grow within 3 to 6 months. Toenails grow at about half or one-third the rate of fingernails, so completely removed toenails may grow within 18 months.
To speed up the process, taking biotin supplements may help. Biotin is a vitamin that helps your body do many important things, like turning your food into energy. Most people get enough biotin through their diet, with foods such as fish and seeds being good sources. However, some people with brittle nails may benefit from extra biotin. Studies show that taking 2.5 mg (2,500 mcg) of biotin daily may improve nail firmness, hardness, and thickness.
Biotin supplements are available in various forms, such as softgels, tablets, capsules, and oils. Some popular brands include Nature's Bounty, NAKED Biotin, and VITBOOST Biotin. These supplements often contain additional ingredients like hyaluronic acid, collagen, and keratin, which are also believed to promote nail health.
While taking biotin supplements is generally safe, it's important to consult with a healthcare professional before starting any new supplement regimen. Additionally, keep in mind that biotin can interfere with the accuracy of certain lab tests.

Keep the wound clean and dress it with a bandage
Keeping the wound clean and dressing it with a bandage is essential for promoting healing and preventing infection after a nail removal. Here are some detailed steps to ensure proper wound care:
Cleaning the Wound:
- Wash your hands thoroughly with soap and water before tending to the wound to prevent introducing new bacteria to the site.
- Gently cleanse the wound with unscented soap and water. Use a soft washcloth or sterile gauze pad to avoid irritating the area.
- Rinse the wound thoroughly to remove any soap residue, as it may cause irritation.
- Ensure the wound is clean and dry before dressing it. You can use sterile gauze or a soft cloth to pat the area dry gently.
Dressing the Wound:
- Apply a thin layer of petroleum jelly, such as Vaseline, to the wound. This helps to keep the area moist and promotes healing.
- Cover the wound with a non-stick, sterile bandage. Adhesive bandages work well to keep the wound protected and secure.
- Change the bandage regularly, especially if it gets wet. Always use a fresh, sterile bandage to reduce the risk of infection.
- Keep the wound dressed until it has healed sufficiently. This usually takes a few days, but the time may vary depending on the severity of the injury.
It is important to note that you should avoid using any sharp objects near the wound, as this can cause further injury and increase the risk of infection. Additionally, always wash your hands before and after tending to the wound to maintain proper hygiene and prevent infection.

Visit a physician if there are signs of infection
While nails have a good regeneration capacity, they grow slowly, and it may take some time for a removed nail to grow back. Fingernails may grow one-tenth of a millimeter each day, so completely removed fingernails usually grow within 3 to 6 months. Toenails grow at about half or one-third the rate of fingernails, so completely removed toenails may take up to 18 months to grow back.
If you have had a nail removed, it is important to follow your physician's postoperative care instructions. Typically, you should avoid putting any pressure on the affected hand or foot for the first 24 hours. You should also elevate the affected foot while resting for the first 24 to 48 hours to help reduce pain and swelling. It is also important to complete the course of prescribed medication, such as antibiotics and painkillers, as advised by your physician.
In most cases, a visit to the physician is not necessary for a removed nail. However, if there are signs of infection, swelling, increasing pain, or pus that develops a few days after the injury, it is mandatory to seek medical attention. Paronychia, a common nail infection, can be caused by bacteria or fungi. It is characterized by redness, swelling, and pain around the nail, often at the cuticle or hangnail. In some cases, there may be pus-filled blisters, especially with bacterial infections. If left untreated, paronychia can lead to serious complications, and the infection may spread beyond the nail. Therefore, it is important to seek medical treatment if you suspect an infection.
Additionally, if there is significant damage to the nail matrix or nail bed, it may result in permanent nail deformities or defects. In such cases, a physician should be consulted to determine the appropriate course of treatment. Minor damage to the nail matrix can be treated with a minor surgical procedure to improve the nail's appearance. However, more significant damage can lead to permanent deformation, and the nail may not grow back properly. Therefore, it is crucial to protect the nail bed and matrix during the healing process and follow the physician's instructions for proper nail care.
