Fingernails and toenails are made of protein and fat and are not live tissue. Nails have a good regeneration capacity and will grow back after being removed, although this may take several weeks or months. The rate of nail growth depends on various factors, including age, diet, and general health. Proper postoperative care is essential to ensure the nail grows back correctly and to prevent infection.
| Characteristics | Values |
|---|---|
| Nail regrowth | Nails grow back, but it may take time. |
| Nail growth rate | Fingernails may grow one-tenth of a millimeter each day, so completely removed fingernails usually grow within 3-6 months. Toenails may grow at about half the rate of fingernails, so they may take up to 18 months to grow back. |
| Nail matrix | The nail matrix is the "factory" where new nails are produced. If the nail matrix is not damaged, the nail will typically regrow. |
| Post-removal care | Keep the nail bed clean, dry, and covered with petroleum jelly and a bandage. Change the bandage if it gets wet. |
| Post-removal recovery | It may take less than 4 weeks to fully recover from a nail removal procedure. |
| Nail damage prevention | Keep nails short and wear well-fitting shoes to reduce the risk of nail damage. |
| Nail injuries | Bruises, tears, or detachments from the nail bed can occur due to trauma or injury. |
| Nail infections | Infections such as fungal infections, nail psoriasis, and bacterial infections can affect nail growth and require medical attention. |
| Nail disorders | Nail disorders can indicate underlying problems such as anemia, kidney disease, heart disease, diabetes, and skin conditions like eczema and psoriasis. |

What You'll Learn
Nails will grow back, but slowly
Losing a nail can be a painful experience. Nails are made of protein and fat and are not live tissue. However, they do grow back, even if slowly. Fingernails may grow at a rate of about one-tenth of a millimeter or 0.13 inches per day, and toenails may grow at about half that rate. This means that it may take up to 6 months for fingernails to grow back and up to 18 months for toenails.
The nail matrix, the whitish moon-shaped area at the base of the nail, is where the body makes new nails. If the nail matrix is not damaged, the nail will typically regrow. Minor damage to the nail matrix will produce minor defects in the new nail, while more significant damage can result in permanent deformity. In the case of severe damage to the nail matrix, some or all of the nail may not grow back.
To promote nail growth, it is important to keep the wound clean and dry, covering it with a bandage and applying antibiotic ointment to prevent infection. It is also recommended to keep the affected foot or hand elevated while resting to help decrease pain. A well-rounded diet and good general health can also contribute to strong nails. Additionally, biotin supplements can promote cell growth and help the body metabolize protein-building amino acids, contributing to faster nail growth.
While nail regrowth may take some time, with proper care, it is possible to support the process and eventually regain normal-looking nails.

Keep the nail bed dry and clean
Keeping the nail bed dry and clean is crucial for preventing infections and ensuring proper healing. Here are some detailed instructions to achieve this:
Clean the Nail Bed:
- If there are any unattached nail remnants, gently remove them with a nail clipper or appropriate tool.
- Wash the nail bed with a soapy washcloth and warm water to remove any foreign material, debris, or blood that may be present. Ensure you use a clean washcloth and gentle, unscented soap to avoid irritating the area.
- Rinse the area thoroughly to avoid soap residue, which can cause irritation or dryness.
Keep the Nail Bed Dry:
- After cleaning, gently pat the area with a clean towel or cloth to ensure it is completely dry.
- Apply a thin layer of petroleum jelly or neomycin ointment to the nail bed. This helps keep the area moist and promotes healing.
- Cover the nail bed with a clean, dry adhesive bandage. This will protect the area and prevent moisture from reaching it.
- Change the bandage regularly, especially if it gets wet. Always use a fresh, dry bandage to maintain dryness and avoid potential infections.
Signs of Infection:
- Keep a watchful eye for any signs of infection, such as increasing heat, redness, pain, tenderness, swelling, or pus.
- If you notice any of these symptoms, seek medical advice promptly to prevent further complications.
Additional Tips:
- Keep your hands or feet elevated whenever possible, especially during the initial healing phase. This helps reduce pain and swelling.
- Avoid any pressure or impact on the affected area for at least the first 24 hours. Slowly resume your regular activities as advised by your healthcare provider.
- If you had a toenail removed, wear properly fitted footwear and recommended cotton socks to protect the nail bed and aid in the healing process.

Postoperative care
Nails have a good regeneration capacity and will grow back after being removed, although this may take several months. The time it takes for a nail to grow back depends on whether it is a fingernail or toenail, and whether the whole or part of the nail was removed.
- Avoid putting any pressure on the affected foot or hand for the first 24 hours.
- Elevate the affected foot while resting for the first 24 to 48 hours to help decrease pain and reduce the risk of swelling and bleeding.
- Wear appropriately fitted footwear if the procedure was performed on the toenail, and wear cotton socks as recommended by your doctor.
- Take any prescribed medication, such as painkillers and antibiotics, as advised by your doctor. Avoid taking non-prescription medications, such as aspirin.
- You can resume showering, but keep the wound clean and dry. Gently wash the wound with unscented soap.
- If you experience any signs of infection, such as warmth, redness, swelling, or pus, seek medical treatment.
- If you have had a toenail removed, keep your nail bed clean and dry, and cover it with a bandage. Change the bandage once a day and apply antibiotic ointment to prevent infection.
- Take biotin supplements to promote cell growth and help your body metabolize protein-building amino acids, contributing to faster nail growth.
- Apply a cold compress for up to 20 minutes to reduce swelling and inflammation. Wrap a cloth over an ice pack before applying it to your skin.
- Do not take part in any exercise until your toe is healed.

Ingrown toenails
There are several causes of ingrown toenails, including:
- Incorrect toenail trimming: Cutting toenails too short, especially on the sides of the big toes, can cause the nail to curve and grow into the skin.
- Improperly fitting shoes: Tight or short shoes can place pressure on the toes and cause the nail to grow into the surrounding tissue.
- Toe trauma: Stubbing or banging the toe can cause the nail to grow into the skin.
- Nail infections: Infections can affect the shape and growth of the nail, increasing the risk of ingrown toenails.
To prevent ingrown toenails, it is recommended to trim toenails straight across without tapering or rounding the corners. Keeping toenails at a moderate length and wearing properly fitting shoes can also help prevent ingrown toenails.
Treatment for ingrown toenails depends on the severity of the condition. Mild cases can often be treated at home by soaking the foot in warm water several times a day and keeping the foot dry at other times. However, if the ingrown toenail becomes infected, it may require medical treatment, including oral antibiotics or partial or complete removal of the nail. In some cases, surgery may be necessary to prevent the nail from growing inward again.
If an ingrown toenail is removed, it will typically grow back within 12 to 18 months. However, complete removal of the nail increases the likelihood that the nail will grow back deformed. Therefore, it is essential to take proper care of the nail bed and follow postoperative care instructions provided by a doctor.

Nail matrix damage
The nail matrix is the region where your fingernails and toenails are formed. It is located at the base of the nail and is responsible for producing the cells that form your nail. The nail matrix has two parts: the germinal matrix and the sterile matrix. The germinal matrix is responsible for about 90% of nail growth, while the sterile matrix keeps the nail attached to the underlying skin.
Injuries and certain health conditions can damage the nail matrix and affect nail growth. Minor matrix damage can cause temporary changes in the nail's appearance, such as dents, horizontal ridges, pain, splits, spots, or texture changes. Severe trauma, such as crushing injuries or deep cuts, can result in long-term or permanent damage to the nail matrix. This may lead to lasting changes in nail growth, including chronic thickening, uneven growth, or, in rare cases, complete and permanent nail loss.
If the nail matrix is not permanently damaged, the nail will typically regrow, although it may take several weeks to several months for the new nail to appear. Proper medical care is essential for nail regeneration. In some cases, minor surgical procedures may be required to improve the nail's appearance.
It is important to protect your nails to reduce the risk of trauma. Wearing protective gloves during repetitive tasks or heavy lifting can help prevent injuries. Keeping nails trimmed and well-maintained also minimizes the chance of breakage. Additionally, maintaining a well-rounded diet and good general health can contribute to strong and healthy nails.
