Healthy nails are an important part of fingertip function, providing support for the finger pad and improving sensation. However, maintaining nail health can be challenging, especially with the desire for beautiful, long-lasting nail polish. Nails can be damaged by gel manicures, acrylics, and injuries, such as smashing a finger or cutting with a sharp object. Minor nail injuries that don't require medical attention and leave the nail bed undamaged can heal within a few days. More severe injuries, such as nail avulsion or damage to the nail bed, can take significantly longer to heal, with the nail bed taking about 7 to 10 days to heal and a new fingernail taking 3 to 6 months to grow back. Toenails typically take even longer, ranging from 12 to 18 months for regrowth. To promote nail healing, it's recommended to moisturize nails regularly, avoid nail polish for a few weeks, and protect nails from further harm by wearing gloves during activities that may cause irritation.

What You'll Learn
Healing time depends on the severity of the injury
The healing time for a nail injury depends on the severity of the injury. If you have lost your nail, it will take about 7 to 10 days for the nail bed to heal. A new fingernail will take about 4 to 6 months to grow back, while a toenail will take about 12 months. During this time, you can strengthen your nails by keeping them short and moisturized and by forgoing nail polish. You can also take steps to protect your nails from further harm, such as wearing gloves when using cleaning products.
If you have broken the bone in your finger or toe along with your nail injury, it will take about 4 weeks for the bone to heal. For more serious injuries, such as lacerations or amputations of the nail, nail bed, or surrounding skin, it is best to go to a hospital's emergency department. If there is a possibility of infection, or if there are signs of swelling, increasing pain, or pus, it is important to seek medical attention.
In some cases, a nail injury may result in permanent deformity, even with proper repair. This can include grooves or dents in the nail, or the development of a hook nail, where the nail grows in a hook over the end of the finger or toe. To minimize the risk of permanent damage, it is important to follow the treatment plan recommended by a healthcare professional. This may include taking antibiotics, keeping the wound clean and dry, and following any specific wound care instructions.
The healing time for a nail injury can vary depending on the severity of the injury and the treatment provided. It is important to seek medical attention for more serious injuries and to follow the recommended aftercare instructions to promote healing and reduce the risk of complications.

The nail matrix and its role in healing
The nail matrix is a vital structure within the nail unit, responsible for creating new nail plate cells. As these new cells are formed, older cells are pushed forward, resulting in the growth of the nail plate. The nail matrix has two parts: the germinal matrix and the sterile matrix. The germinal matrix, located below the lunula (the white, half-moon cells at the nail's base), contributes about 90% of nail production, giving the nail its natural curvature. The remaining 10% of nail cells are produced in the sterile matrix, which is responsible for keeping the nail attached to the underlying skin.
The size and shape of the nail matrix determine the thickness and width of the nail. A longer nail matrix corresponds to a thicker nail, while a smaller matrix leads to a thinner nail. Any damage to the nail matrix can have repercussions on the nail's overall health and appearance. Minor damage may result in temporary changes, such as dents, horizontal ridges, soreness, splits, or texture changes. Severe injuries can cause the nail to fall off, and in cases of extensive damage, the nail may not grow back.
Injuries to the nail matrix can occur through various means, including pinching, crushing, or dropping something heavy on the finger or toe. Additionally, certain health conditions can affect the nail matrix, such as fungal infections, illnesses (e.g., heart attack, COVID-19, pneumonia), and traumas. Maintaining the health of the nail matrix is crucial for optimal nail growth and can be achieved through proper care and protection. This includes practices that promote nail hygiene, prevent excessive pressure or trauma to the matrix area, and ensure a well-balanced diet for strong and resilient nails.
Healing a damaged nail typically takes several weeks to months. During this time, it is important to prioritize nail hygiene, keep nails trimmed, and moisturize them regularly. Avoiding nail polish for a few weeks can also help prevent the buildup of bacteria and fungus. In cases of severe damage or nail loss, it may take about 4 to 6 months for a fingernail to grow back and 12 months for a toenail to regrow. Proper care and protection of the nail matrix are essential to support the healing process and promote healthy nail growth.

Home treatment for minor nail injuries
The healing time for a nail injury depends on the severity of the injury. A fingernail that has fallen off due to injury will take around 4 to 6 months to grow back, while a toenail can take about a year. In the case of a broken bone in the finger or toe, along with a nail injury, it will take about 4 weeks to heal.
- If there is bleeding, apply pressure with a clean cloth to stop it.
- If there are any cuts or scrapes, gently wash them with soap and water, then apply a bandage.
- If there is swelling, ice the area and elevate the injured area above the level of your heart.
- Take over-the-counter pain medication such as acetaminophen (Tylenol) or ibuprofen (Advil, Aleve) if you are not allergic to these medications.
- If the nail is torn, use sterile scissors to cut off any rough edges to prevent further injury.
- If the injury is minor, such as a small nail bruise, you can treat it at home by keeping your hand or foot elevated and taking pain medication as needed.
It is important to note that for more serious nail injuries, such as deep wounds, fractures, or avulsions, it is recommended to seek medical attention at a hospital's emergency department.

When to seek medical attention
It is important to seek medical attention for a nail injury in certain situations to ensure proper healing and prevent further complications. Here are some scenarios where you should seek professional help:
- Serious Injuries: If you have a severe nail injury, such as a deep cut, tear, or smash involving the nail bed or cuticle, go to an urgent care centre or emergency room. They have the necessary equipment to stop the bleeding, clean the wound, and provide appropriate treatment.
- Bone Fractures: If you suspect a broken bone in your finger or toe, especially if there is an obvious bend or deformity, seek medical attention immediately. A wire may need to be placed in your finger or toe to keep the bone in place, and you may be given a splint or special shoe to protect the injured area during healing.
- Large Bruises: If your nail bruise covers more than 25% of your nail and you want it drained, or if there is a large bend or deformity in the fingertip, see a doctor. They may create a small hole in your nail to drain the blood and relieve pressure and pain.
- Nail Avulsion: In cases of nail avulsion, where the nail is torn away from the skin, seek medical attention. Doctors can determine if the nail can be reattached or if a synthetic nail is needed. They will also address any associated nail bed injuries, which are common in avulsion cases.
- Infection Risk: If you have not had a tetanus booster shot in over ten years, or if you develop signs of infection such as redness or drainage at the injury site, seek medical attention. Additionally, if you have underlying conditions such as diabetes, poor circulation, AIDS, or are undergoing chemotherapy, you are at increased risk of infection and should consult a doctor.
- Fingertip Amputation: If you have experienced a fingertip amputation, where the tip of your finger has been severed, seek emergency medical care. While reattachment may not always be possible, advanced techniques may be available at major medical centres to improve the appearance of your finger.

Preventing nail injuries
Nail injuries can take anywhere from a few days to several months to heal, depending on the severity of the injury. While some minor nail injuries can be treated at home, more serious injuries may require a visit to an urgent care centre or the emergency room. To prevent nail injuries and ensure the optimal healing of your nails, consider the following:
Keep Nails Trimmed and Well-Maintained
A simple yet effective way to prevent nail injuries is to maintain short and properly trimmed nails. This helps to prevent your nails from bending, catching on objects, or suffering trauma from crushing or tearing injuries. When cutting your nails, trim your fingernails with a slight curve at the edges, and cut your toenails straight across, avoiding cutting them too short. Proper nail trimming can also help prevent ingrown toenails.
Protect Nails During Activities
When engaging in sports or activities that may pose a risk to your nails, it is essential to wear protective gear. This could include gloves, appropriate footwear, or other specialised equipment designed to safeguard your nails from potential trauma.
Choose Proper-Fitting Footwear
Ill-fitting shoes can cause rubbing and pressure on your nails and toes, potentially leading to nail injuries and conditions such as ingrown toenails. Opt for shoes that fit well and have a wide toe box to provide ample space for your toes and nails.
Manage Any Underlying Health Conditions
Certain health conditions, such as psoriasis or fungal infections, can affect the health and integrity of your nails. Regularly consult with your healthcare provider to manage these conditions effectively and minimise the risk of nail-related complications.
Avoid Cuticle Manipulation
The cuticle is the delicate skin at the base of your nail, and it plays a crucial role in nail health. Avoid manipulating or cutting your cuticles, either at home or during manicures or pedicures, as this can lead to damage and increase the risk of infection.
By following these preventive measures, you can significantly reduce the likelihood of nail injuries and promote the overall health and well-being of your nails.

Frequently asked questions
Damage from a gel manicure is often reversible. With the right treatments, gentle ingredients, and care, you can gradually nurse your nails back to health. It takes about 4 to 6 months for fingernails to grow back, and 12 to 18 months for toenails.
To help your nails heal faster, you can moisturize them daily with oil or serum. You can also try to keep your nails trimmed short, as this can help them grow stronger. Another way to promote nail health is to take a break from nail polish for a few weeks to prevent bacteria and fungus from building up.
If you experience a nail injury, the first step is to stop any bleeding by applying pressure with a clean cloth. If the bleeding is severe or the injury is complex, go to an urgent care center or the emergency room. For minor nail injuries, a few days should suffice for healing, but if the nail falls off or the nail bed is damaged, it will take about 7 to 10 days for the nail bed to heal and 3 to 6 months for the nail to grow back.
