Losing a nail can be painful and distressing, but thankfully, nails do grow back. Fingernails usually grow back within six months, while toenails can take up to 18 months to fully regrow. Nails have a good regeneration capacity, but their growth rate can vary depending on overall health, age, and underlying conditions. It is important to keep the nail bed clean, dry, and protected during the healing process, and to watch for signs of infection.

What You'll Learn
Fingernails can take up to 6 months to grow back
Fingernails can take up to six months to grow back, and toenails can take up to 18 months. Nails have a good regeneration capacity, but they grow slowly. Fingernails may grow at a rate of one-tenth of a millimetre each day, so completely removed fingernails usually grow back within six months. Toenails may grow at about half or a third of the rate of fingernails, so it can take much longer for them to grow back.
The rate of nail growth can vary from person to person and may be influenced by several factors. For example, overall health can impact nail growth, with sickness and malnutrition potentially slowing it down. Hormones can also affect regrowth, and toenails and fingernails might grow quicker during pregnancy. Additionally, ageing and diseases may decrease blood flow to the hands and feet, sometimes slowing the rate of nail growth.
It is important to keep the nail bed dry, clean, and covered with petroleum jelly and an adhesive bandage until the nail has grown back. Applying a new bandage when the old one gets wet is essential to maintaining hygiene and protection. Keeping the wound clean and dry is crucial, and gently washing it with unscented soap is recommended.
In some cases, such as fungal nail infections, toenail removal may be recommended as part of a comprehensive treatment plan. Toenail fungus can live on the nail and the nail bed, and removing the nail exposes the nail bed, allowing topical medications to penetrate and potentially increasing the efficacy of the treatment. However, it is important to note that the toenail may grow back thickened, and other options may need to be considered.

Toenails can take up to 18 months to grow back
Toenails can take a long time to grow back, up to 18 months in some cases. Nails have a good regeneration capacity, but they grow slowly. Toenails grow at about half to a third of the rate of fingernails, which typically take around six months to grow back.
There are several reasons why a toenail might fall off or need to be removed. Trauma is one of the most common reasons, which could be caused by stubbing your toe, dropping something heavy on your foot, or wearing ill-fitting shoes. Toenails can also become thick and brittle due to fungal infections, eventually leading to the nail falling off. In some cases, a toenail might need to be surgically removed due to severe fungus, recurrent ingrown toenails, or when a large section of the nail is diseased or damaged. Ingrown toenails occur when the side corners of a toenail grow down into the skin and pierce the soft tissue.
After a toenail is removed or falls off, it's important to take care of the injured area to promote faster healing. The area should be kept clean and dry, and covered with a bandage. It's also important to watch for signs of infection, such as increasing heat, redness, pain, tenderness, swelling, or pus. If the toenail falls off due to a fungal infection, it's important to seek treatment to ensure that the new nail grows in healthy.
While waiting for the toenail to grow back, there are temporary solutions to help you feel more confident. Podiatric Nail Restoration Systems use a flexible, breathable resin that allows your nail to grow underneath while providing a natural-looking temporary nail. It's important to understand which options are safe and which could potentially harm your healing nail bed. For example, acrylic nails can trap moisture and bacteria, leading to potential infections and complications.

Nails grow from the matrix, the root of the nail
Nails have a good regeneration capacity and will grow back after being removed, although this may take several weeks or months. The nail matrix, or root of the nail, is the area where your fingernails and toenails start to grow. It is located at the base of the nail and creates new cells that allow your nail to grow. The nail matrix is also known as the matrix unguis, keratogenous membrane, or onychostroma.
The matrix produces cells that become the nail plate, which is the top of the nail. The width and thickness of the nail plate are determined by the size, length, and thickness of the matrix. As new nail plate cells are made, they push older nail plate cells forward; in this way, older cells become compressed, flat, and translucent. The nail plate is flat, arched, or hooked depending on the shape of the fingertip bone.
The nail matrix is made up of the germinal matrix and the sterile matrix. The germinal matrix, located below the lunula (closest to the knuckle), produces about 90% of nail cells and gives a natural curvature to the nail. The sterile matrix, located above the lunula, produces the remaining 10% of nail cells and is more important in keeping your nail attached to the underlying skin.
Injuries to the nail bed or disorders that affect the matrix can interfere with nail growth. Minor damage to your nail matrix can temporarily change your nail’s appearance. A severe injury could cause your nail to fall off. Once your nail matrix heals, your nail will usually start to grow again. However, in cases of severe nail matrix damage, some or all of your nail may not grow back.
Certain health conditions and other factors can affect your nail matrix and nail growth. For example, fungal infections, skin conditions such as eczema and psoriasis, and illnesses such as heart attacks, COVID-19, pneumonia, and cancer can all impact nail growth. Additionally, peripheral artery disease causes reduced blood flow to the legs and feet, which can make nail growth slower.

Postoperative care is important to prevent infection
Nails have a good regeneration capacity and will grow back after being removed. Fingernails may take up to 6 months to grow back, while toenails may take up to 18 months. Postoperative care is crucial to prevent infection and ensure proper healing. Here are some detailed instructions for postoperative care:
Keep the Wound Clean and Dry
It is essential to maintain proper hygiene and dryness at the wound site. Gently wash the surgical wound with unscented soap and warm water, then pat it dry. Keep the nail bed dry, clean, and covered with petroleum jelly and an adhesive bandage or dressing until the nail has grown back. Change the bandage or dressing regularly, especially if it gets wet.
Monitor for Signs of Infection
Be vigilant for any signs of infection, such as increased redness, swelling, pain, tenderness, warmth, or discharge from the wound. Other signs may include fever, chills, or the presence of pus. If any of these symptoms occur, contact your healthcare provider as you may require antibiotics or further treatment.
Foot Soaks and Appropriate Footwear
Soaking your foot in Epsom salt can provide pain relief and reduce inflammation. Additionally, wear appropriate footwear that supports healing and avoids putting pressure on the affected area. Avoid tight, pointy shoes, and opt for comfortable, roomy shoes that will not irritate the wound.
Cut Nails Straight Across
To prevent future ingrown toenails, practice proper nail care. Cut your nails straight across and avoid cutting them too short or curving the edges. This helps prevent the nail from growing into the surrounding nail fold, which can cause pain and discomfort.
Follow-up with a Healthcare Professional
Schedule a follow-up appointment with your doctor or podiatrist to ensure proper healing and monitor for any signs of infection. They can assess your recovery progress and provide further treatment recommendations if needed.
By diligently following these postoperative care instructions, you can effectively prevent infection and promote the healing process after a nail removal procedure.

Nails protect your skin, but can be lost due to trauma or infection
Nails are composed of several layers of dead, compacted cells, which make them strong yet flexible. The cuticle, a small strip of skin at the bottom of the nail, acts as extra protection from germs entering the nail bed. The eponychium, the fold of skin cells that produces the cuticle, and the cuticle itself form a protective seal. The paronychium, the soft tissue border around the nail, is the site of hangnails, ingrown nails, and paronychia, a skin infection. The hyponychium, located beneath the nail plate at the junction between the free edge and the skin of the fingertip, forms a seal that protects the nail bed.
Nails protect the distal phalanx, the fingertip, and the surrounding soft tissues from injuries. They also serve to enhance precise delicate movements of the distal digits through counter-pressure exerted on the pulp of the finger. The nail then acts as a counter-force when the end of the finger touches an object, thereby increasing the fingertip's sensitivity.
Nail injuries are common, with nail bed injuries being the most common type of fingertip injuries seen in emergency rooms. Nails can be lost due to trauma or infection. Trauma can occur from crushing forces, such as hammers or doors slamming on fingers, slicing or cutting, and tearing or ripping. Nail separation from the nail bed can result from injury, particularly in people with long fingernails, as the nail may pry away from the nail bed when hit or jammed. Toenails may detach due to severe or repetitive stubbing, commonly seen in athletes wearing tight shoes.
Infection can also lead to nail loss. Fungal nail infections occur when fungi invade the nail and the skin underneath, with toenails being more commonly affected than fingernails. Symptoms include cracked, yellow, discoloured, streaked, thickened, or spotted nails. Bacterial infections are also common, and certain skin conditions, such as psoriasis, can contribute to nail loss.
