Fingernails and toenails can often grow back after being damaged or lost, but the process is slow and can take anywhere from 4 to 18 months for a fingernail and up to 2 years for a toenail to fully regrow. The nail matrix, the part of the nail bed where new nail cells are produced, is responsible for nail growth. As long as the nail matrix is not severely injured, nails will typically grow back with proper care and treatment.

What You'll Learn
Fingernails grow back in 4-6 months, toenails in 6-24 months
Fingernails and toenails can fall off due to various reasons, including injuries, fungal infections, skin conditions, and severe illnesses. The good news is that they grow back! The nail matrix, the part of the body where nails form, has regenerative abilities. As long as the nail matrix is not severely injured, it will continue to produce new nail cells that grow at approximately 0.1 mm per day or about 1/10 of an inch per month.
The time it takes for nails to grow back depends on various factors, including the reason for nail loss, age, climate, overall health, and hormones. Nails tend to grow slower in older adults, in colder climates, and in individuals who are sick or malnourished. On the other hand, nails grow faster in the summer, during pregnancy, and in the dominant hand.
Fingernails typically take 4 to 6 months to completely regrow. During this time, it is important to keep the nail bed dry, clean, and covered with petroleum jelly and an adhesive bandage. Watch for signs of infection such as increasing heat, redness, pain, tenderness, swelling, or pus.
Toenails grow more slowly than fingernails, requiring up to 6 to 24 months for full regrowth. Toenails are more susceptible to fungal infections due to the warm and wet environment created by shoes and socks. To promote healing and prevent infection, keep the area dry and cover it with tape or an adhesive bandage until the nail has grown out enough to protect the toe.

Nail matrix damage can affect nail regrowth
Fingernails and toenails are made in the nail matrix, a delicate structure located just below the nail fold. The matrix is responsible for nail growth and regeneration, as well as supplying nutrients to the nail bed.
The nail matrix can be damaged by mechanical injuries, such as a sharp blow or crushing injury, or by improperly performed nail care procedures. For example, cuticle picking, improper use of a drill, and excessive pressure when using a cuticle pusher can all damage the nail matrix.
When the nail matrix is damaged, it can affect nail regrowth and the appearance of the nail. The new nail may have an abnormal appearance, with potential issues including dents, horizontal ridges or lines, pain, soreness, splits, cracks, spots or streaks of colour, and texture changes. In some cases, the nail may need to be removed and the nail bed repaired. While fingernails typically regrow within 4-6 months, toenails can take up to 18 months for full regrowth.
However, it is important to note that nail matrix damage does not always prevent nail regrowth. With proper treatment, healthy nails can often grow back. The nail matrix has a remarkable ability to heal, and even if the nail falls off, it usually grows back with proper medical care.

Nail trephination helps new nail growth after injury
Fingernails and toenails can grow back after being damaged or lost. The nail matrix is where your fingernails and toenails form. It has two parts: the germinal matrix and the sterile matrix. The former produces most of the nail plate, while the latter is located underneath the nail and is responsible for anchoring the nail. The nail matrix is highly regenerative, and as long as it is not severely injured, it will continue to produce new nail cells. Nails typically take 4-6 months to completely regrow, with toenails requiring up to 18 months.
Nail injuries can cause a subungual hematoma, which is when bleeding develops under the nail due to a direct blow or crush injury. This can result in pain and discoloration of the nail. Trephination is a procedure that can be used to treat subungual hematomas by draining the blood from under the nail, thereby relieving pressure and pain. It is important to perform trephination within 24 to 48 hours of the injury, before the blood clots. While trephination is generally safe, there is a risk of infection, further trauma, and delayed healing.
Nail trephination can help new nail growth after injury by relieving the pressure and pain caused by a subungual hematoma. This allows the nail matrix to continue producing new nail cells without obstruction. Additionally, trephination can prevent the need for more extensive treatment, such as the removal of the nail plate, which may be required if the hematoma is left untreated.
While fingernails and toenails typically grow back after being damaged or lost, there are cases where the nail matrix may be permanently damaged, affecting nail growth and appearance. Proper medical care is essential to promote nail regrowth and prevent complications. Home treatments, such as keeping the nail bed dry, clean, and covered, can also help relieve pain, promote healing, and prevent infection.

Toenails are susceptible to fungal infections
Toenails are particularly susceptible to fungal infections. Toenail fungus occurs when fungi get between the toenail and the toenail bed, usually through a crack or cut in the toe. This fungus thrives in warm, moist, and dark environments, such as the feet. Therefore, walking barefoot in public areas like swimming pools, locker rooms, or gyms can increase the risk of contracting toenail fungus.
Toenail fungal infections can be caused by various fungi, with dermatophytes being responsible for 90% of cases. Tinea unguium, also known as onychomycosis, is a common type of toenail fungus caused by dermatophytes. This infection can lead to thickened, discoloured, and brittle nails that may become painful and swollen.
The treatment of toenail fungal infections can be challenging and may require several months of therapy. Healthcare providers typically examine the affected toenail and may take a small sample for microscopic analysis to confirm the diagnosis. Toenail fungus often recurs, and proper medical care is necessary to promote nail regrowth and prevent further complications.
It is important to note that nail polish can trap moisture underneath the nail bed, creating an ideal environment for fungal growth. Therefore, individuals with toenail fungus should avoid wearing nail polish and seek appropriate treatment. In some cases, infected nails may need to be removed under local anaesthesia to facilitate healing and prevent the spread of the infection.
Additionally, maintaining proper nail hygiene and trimming toenails straight across can help prevent ingrown toenails and reduce the risk of fungal infections. Overall, while toenails are susceptible to fungal infections, prompt treatment and adherence to medical advice can effectively manage and resolve this condition.

Nails grow slower in older adults and colder climates
Fingernails and toenails grow back after being damaged or lost. The nail matrix—the specialised tissue beneath the skin that produces new nail cells—remains mostly intact even when the nail is lost. The nail matrix has two parts: the germinal matrix, which produces most of the nail plate, and the sterile matrix, which aids in anchoring the nail. The nail bed lies beneath the nail plate and contains blood vessels that nourish the growing nail. As the matrix creates new cells, older cells are pushed forward, flatten, harden, and compact together to form the nail plate.
The nail growth process is slow and requires patience. Fingernails grow approximately 0.1 mm per day or about 1/10th of an inch per month. Toenails grow even more slowly, requiring up to 18 months for full regrowth.
Nail growth slows down as people age. This is part of the normal ageing process and is caused by changes in the growth rate and morphology of the nail plate. The exact mechanisms behind these changes are not fully understood but may be related to dysfunctional blood circulation in the extremities or the effects of ultraviolet radiation. Additionally, older adults may experience other nail changes, such as dull and brittle nails, yellowing and opacity, and thickening of the nails, particularly toenails.
Nail growth also tends to slow down in colder climates. This is due to several factors, including reduced sunlight exposure, which leads to lower vitamin D production, a crucial nutrient for nail health and strength. Dietary changes in the winter may also result in fluctuations in vitamin intake, impacting nail growth. Colder temperatures can cause constriction of blood vessels, particularly in the hands and feet, leading to reduced blood flow and oxygen, nutrient, and growth factor delivery to the nails.
