Fingernails and toenails are made of special cells produced by the nail matrix. The nail matrix is the factory where your body makes new nails. Nails have good regeneration capacity, but they grow slowly. Fingernails may grow one-tenth of a millimeter each day, so completely removed fingernails usually grow within 6 months. Toenails may take up to 18 months to grow back. However, if the root of the nail is damaged, the nail may never grow back.
| Characteristics | Values |

| Do fingernails grow back if pulled out? | Yes, if the root is intact and the nail matrix is not damaged, the nail will grow back. |
| How long does it take for fingernails to grow back? | Fingernails may grow one-tenth of a millimeter each day, so they usually take 3-6 months to regrow completely. |
| What affects nail growth? | Ageing, diseases, injuries, certain health conditions, and illnesses can affect nail growth. |
| How to prevent nail damage? | Keep nails short, wear well-fitting shoes, and avoid barefoot activities and dangerous situations. |

What You'll Learn
Fingernails can grow back within 6 months
Injuries to the nail matrix and nail bed can cause nails to fall off. Minor damage to the nail matrix can cause temporary changes to the appearance of the nail. A severe injury could cause the nail to fall off. If the nail matrix is damaged, the nail may not grow back properly or at all. This can result in a permanent groove in the nail, as the matrix may be scarred.
However, it is rare for the nail matrix to be permanently damaged. As long as the root of the nail is intact, the nail will usually grow back within 3 to 6 months. The rate of growth is about one-tenth of a millimeter per day, or about 0.13 inches per month.
To encourage nail growth, it is recommended to maintain a well-rounded diet and good general health. Nails can be kept strong and healthy with proper care and protection during physical activity.

Toenails can take up to 18 months to grow back
Fingernails and toenails can grow back if pulled out, as long as the root is intact. The nail matrix is the "factory" where the body makes new nails. It is made of special cells that constantly produce new nail cells. The nail matrix is quite resilient, and unless it is permanently damaged, the nail will typically grow back.
Toenails grow more slowly than fingernails, at about one-half or one-third the rate of fingernail growth. This means that a completely removed toenail may take up to 18 months to grow back. Fingernails, on the other hand, typically regrow in 3 to 6 months.
In the case of severe nail matrix damage, some or all of the nail may not grow back. Minor damage to the nail matrix can cause temporary changes in the nail's appearance, such as a difference in texture or how it feels to the touch. Severe injuries can cause the nail to fall off, and if the root is damaged, the nail may never grow back.
Injuries to the nail matrix can occur through pinching or crushing the finger or dropping something heavy on the toe. Ingrown toenails can also cause issues, and in some cases, surgery may be required to remove the nail and "'kill'" the root to prevent it from growing back.
Fungal infections, such as tinea, can also affect the growth of toenails. Toenail fungus may appear as thick, yellow, cracked, or cloudy nails. Proper treatment of fungal infections involves antifungal preparations applied topically or taken orally, as well as professional trimming and care by a podiatrist.

Nail matrix damage can cause permanent nail loss
Fingernails and toenails can grow back after being pulled out, although their appearance may be altered. However, if the nail matrix—the living part of the nail responsible for growth—is severely damaged, some or all of the nail may not grow back.
The nail matrix is located just below the nail fold, which protects it from injuries. Nevertheless, damage to the matrix is a common problem, resulting from mechanical injuries or improperly performed nail care procedures. Mechanical damage to the nail matrix can occur from a blow to the nail, closing the finger or toe in a door or drawer, nail biting, cuticle biting, or repetitive picking at the thumb's nail and cuticle with the index finger. Repeated trauma to toenails, caused by ill-fitting shoes, can also lead to deformities in the nails.
Injuries and certain health conditions can damage the nail matrix and interfere with nail growth. Minor damage to the nail matrix can temporarily change the nail's appearance, causing dents, horizontal ridges or lines, pain or soreness, splits or cracks, spots or streaks of colour, and texture changes such as becoming thicker or crumbly. A severe injury could cause the nail to fall off.
In cases of severe nail matrix damage, some or all of the nail may not grow back. If the matrix is permanently injured, it cannot regenerate. While it is rare for the nail matrix to be permanently damaged, preventing the nail from growing back, external actions can be taken to improve the aesthetics and appearance of the nail using nail styling products.

Nail injuries can be prevented with well-fitting shoes
Nails have a good regeneration capacity, but they grow slowly. Fingernails may grow about one-tenth of a millimeter each day, so completely removed fingernails usually grow back within 3 to 6 months. Toenails grow at about half the rate of fingernails, so completely removed toenails may take up to 18 months to grow back.
The nail matrix is the part of the body responsible for nail growth. It produces 196 layers of cells that combine to make each of our fingernails and toenails. Certain injuries and illnesses can damage the nail matrix and affect how nails look or grow. A severe injury could cause the nail to fall off. However, if the nail matrix is not damaged, the nail will typically regrow. In cases of severe nail matrix damage, some or all of the nail may not grow back.
Minor damage to the nail matrix can temporarily change the nail's appearance. For example, the nail may look flatter or have a different texture. However, with proper medical care, healthy nails can often grow back. It is rare for the nail matrix to be permanently damaged.
To prevent nail injuries, it is recommended to keep nails short and trim them properly. Toenails should be cut straight across to prevent ingrown toenails, while fingernails should be trimmed with a slight curve at the edges.

Nail trephination can relieve bruised nails
Fingernails and toenails can grow back if pulled out, as long as the root, or nail matrix, is intact. This is the "factory" where your body makes new nails. The nail matrix is made of special cells that constantly produce new nail cells. While it is rare for the nail matrix to be permanently damaged, certain injuries and illnesses can affect it and change how your nails look or grow.
One such injury is a bruise under the nail, otherwise known as a subungual hematoma. This occurs when blood enters the space between the nail and the nail bed, causing painful pressure. To treat this, a procedure called nail trephination can be performed to drain the trapped blood and relieve the pressure and pain.
Nail trephination involves making a small hole in the hard part of the nail, known as the nail plate, to release the blood. It is a quick and safe procedure that can be carried out in various settings, including emergency rooms and urgent care clinics. It is important to note that only a healthcare provider should perform this procedure, as attempting it yourself can lead to infection or further damage.
The healthcare provider will use a needle, an electrocautery device, or a special tool designed for trephination to create the hole. They will position the device over the middle of the bruise and apply gentle pressure to make a hole deep enough to release the blood. The procedure only goes through the nail plate and does not affect the tissues below it. After the blood has drained, a sterile bandage is applied, and the patient is instructed on how to care for their finger or toe as it heals.
Nail trephination is an effective way to relieve the pain and pressure associated with a bruised nail, and it can help ensure that the nail grows back correctly. It is important to seek treatment within 48 hours of the injury, as blood within a subungual hematoma will likely clot after this time, and trephination will not be effective.
