Fingernails and toenails are composed of protein and fat and are not live tissue. They grow at a rate of about 0.13 inches per month and require 3-6 months to completely regrow. Toenails grow more slowly than fingernails. Nails are produced by the nail matrix cells that reside in the moon-shaped whitish area (lunula) at the base of the nail. If the nail matrix is not damaged, the nail is typically capable of regrowth. However, if there is damage to the nail matrix, the growing nail plate will contain a defect, and the new nail may not look normal.

What You'll Learn
Fingernails can regrow in 3-6 months
Fingernails and toenails are made of protein and fat and are not live tissue. They grow at a rate of about one-tenth of an inch per month, or 0.13 inches per month, and require 3–6 months to fully regrow. Nails are produced by the nail matrix cells that reside in the moon-shaped whitish area (lunula) at the base of the nail. If the nail matrix is not damaged, the nail will typically regrow. Toenails grow more slowly than fingernails.
If a nail has been detached or torn, there is little that can be done to replace or repair it. The main concern is damage to the surrounding structures. If there is significant damage to the areas around the nail, a visit to a physician may be necessary. Occasionally, after blunt trauma to a nail, there may be bleeding between the nail and the nail bed, resulting in a subungual hematoma. This can be extremely painful, and a doctor can relieve the pressure by drilling a tiny hole in the nail plate to drain the accumulated blood.
If there is no permanent damage to the nail matrix or nail bed, the nail should regrow and appear completely normal. Minor damage to the nail will produce minor defects in the new nail. More significant damage can result in a permanently deformed nail. It is important to take precautions against getting a fungal infection in a nail that has been weakened by injury. Avoid prolonged exposure to water, and keep nail cosmetics off the damaged nail while it is growing back and healing.
In the case of total loss of the nail bed, vascularised nail bed grafts can be used to transfer the nail from the great toe or second toe by microvascular transfer. In some cases, the nail bed may be intact but avulsed from the germinal matrix, in which case it can be reattached to the sulcus using mattress sutures.

Toenails can take up to 6 months to regrow
Toenails, like hair and fingernails, are made of protein and fat and are not live tissue. They grow at a rate of about 0.1 inches per month, slower than fingernails, and typically take 3-6 months to completely regrow. Toenails are produced by the nail matrix cells that reside in the moon-shaped whitish area (lunula) at the base of the nail.
If a toenail has been damaged, it is important to take precautions to prevent infection and further complications. Any sharp ends should be filed down to prevent them from catching on clothing or socks, and the exposed nail bed can be covered with ointment and dressed with a clean bandage. If there is bleeding between the nail and the nail bed, a doctor may need to drill a tiny hole in the nail plate to relieve the pressure of accumulated blood.
In the case of severe damage to the nail bed or surrounding tissues, it may take longer than 6 months for the toenail to regrow, and the new nail may not look normal. If there is significant damage to the nail matrix, the growing nail plate will contain a defect, which may result in a permanently deformed nail. In some cases, the nail may need to be removed and repaired with sutures, and the finger or toe may need to be splinted for several weeks to protect the healing tissues.
It is important to seek medical attention if there are signs of infection, such as pus, redness, or heat around the nail, or if there is intense pain or deformity of the finger or toe. Proper management of nail injuries is essential to ensure good healing and prevent late deformities.

A detached nail can be painful
In the case of a detached nail, there is little that can be done to replace or repair the nail itself. However, the main concern is to prevent damage to the surrounding structures, such as the nail bed and the matrix. If there is significant damage to these areas, it is important to seek medical attention to assess and repair the injury.
The detached nail will not reattach, but treatment options can help manage the condition and promote new nail growth. These options may include trimming the nail, wearing gloves, avoiding nail irritants, changing medications, using supplements, or taking medications to treat a nail infection. With effective treatment, the focus will be on keeping the new nail growth attached to the nail bed.
The recovery time for a detached nail depends on the nail growth rate, which is typically quite slow. Fingernails can take around 3-6 months to regrow completely, while toenails may take up to twice as long. During this time, it is important to care for the nail bed and protect it from infection.

A detached nail may require a doctor's visit
A detached nail can be painful and unsightly. While nails are not live tissue, they protect the nail bed, the skin at the upper tip of the finger or toe. Therefore, a detached nail may expose the nail bed to injury. If there seems to be significant damage to areas around the nail, a visit to a physician may be necessary.
Signs of infection, such as pus, redness, or heat around the nail, or a red streak extending from the wound, are reasons to seek medical attention. Additionally, if there is continuing, intense pain or if more than a quarter of the nail is discoloured, a doctor should be consulted. Occasionally, after blunt trauma to a nail, there may be bleeding between the nail and the nail bed, resulting in a subungual hematoma. This can be extremely painful, and a doctor may need to drill a tiny hole in the nail plate to relieve the pressure of accumulated blood.
If there is damage to the nail matrix, the growing nail plate will contain a defect. While minor damage will produce minor defects, more significant defects can result in a permanently deformed nail. To prevent this, proper management of nail injuries is essential to ensure good healing and prevent late deformities. In some cases, grafts or microsurgical reconstruction may be required to restore the aesthetic appearance of fingers.
In summary, while a detached nail will usually grow back over time, it is important to be vigilant for signs of infection or other complications that may require medical intervention.

A detached nail may not reattach
In the case of a detached nail, the concern is damage to the surrounding structures, such as the nail bed. If there is significant damage to these areas, a visit to a physician may be necessary. Occasionally, blunt trauma to a nail can cause bleeding between the nail and the nail bed, resulting in a subungual hematoma. This can be very painful, and a doctor may need to drill a tiny hole in the nail plate to relieve the pressure of accumulated blood.
To prevent infection and further complications, it is important to address the collection of blood underneath the nail. This can be done by making a hole in the nail, away from the nail bed laceration, to allow the blood to drain. The wound can then be covered with non-adherent dressings, and a protective splint may be advised for the finger or toe for several weeks until the fractures heal.
In some cases, surgical reconstruction may be required to restore the aesthetic appearance of the finger or toe. For example, if there is a total loss of the nail bed, vascularised nail bed grafts can be used to transfer the nail from another toe through microvascular transfer. While the nail may eventually grow back, it may not appear normal, even with the best repair.

Frequently asked questions
If your nail has been damaged, you should first check for any signs of infection, swelling, pain, or pus. If any of these symptoms are present, seek medical attention immediately. You may also need to get an X-ray to check for any bone fractures.
On average, fingernails grow at a rate of 0.13 inches per month and can take 3-6 months to completely regrow. Toenails grow more slowly, usually taking about 6 months to fully regrow.
To encourage nail growth, it is recommended to maintain a well-rounded diet and good general health. It is also important to keep your nail clean and dry, avoiding prolonged water exposure to prevent fungal infections.
If your nail is detached or lifted from the nail bed, it is important to keep the nail cut back to prevent further damage. The nail will not reattach to the nail bed, but it will grow out and attach as it grows. This process can take 6 months or more in severe cases.
If there is minor damage to the nail matrix, the new nail may contain minor defects. More significant damage can result in permanent deformities. Even with proper treatment, there is a possibility that the nail may not look normal.
