Toenails are made of hard keratinized cells that grow from the nail matrix, the root of the nail. When a toenail falls off due to injury or infection, it cannot reattach and continue growing. Instead, a new nail must grow back in its place, which can take anywhere from six months to two years. During the healing process, it is important to keep the nail bed clean and moisturized to prevent infection and promote proper nail growth. Certain underlying conditions, injuries, and illnesses can affect nail growth, and in some rare cases, the nail matrix may be permanently damaged, preventing the nail from growing back altogether.

Toenails falling off: causes and recovery
Toenails are protective barriers for the skin underneath them, but they can fall off due to trauma, fungus, or other reasons. Toenail trauma can be caused by dropping something heavy on the toe, stubbing it, or repeated irritation from running or tight shoes. Toenail fungus can cause the nail to become thick, discoloured, brittle, and deformed, and it can be hard to treat.
If you injure your toenail, you may notice a black or purple discolouration underneath it, which is called a subungual haematoma. This is caused by blood collecting under the injured toenail, and it can lead to nail detachment as the blood builds up and separates from the nail bed. In the case of an injury, it can take several weeks for the toenail to completely fall off.
Fungal infections are another common cause of toenail loss. Fungi can grow between the nail bed and toenail, and certain conditions, such as athlete's foot or diabetes, can increase the risk of a fungal infection. Fungal toenail infections can be difficult to treat, and they may require additional medical attention to ensure the toenail grows back properly.
Other causes of toenail loss include psoriasis, an autoimmune condition that causes skin cells to build up, medications, other health conditions, and chemicals. Losing a toenail can be a painful and unsettling experience, and it may take anywhere from six months to two years for the nail to completely grow back, depending on the cause and the size of the lost toenail.
If your toenail falls off, it is important to keep the wound clean and dry, and to cover it with a bandage to protect it. You should also seek medical attention if you notice any signs of infection, such as redness, swelling, or increased pain. A podiatrist can evaluate the cause, remove any damaged nail tissue, and recommend appropriate treatments to support healthy regrowth.

How to help a toenail grow back quickly
Toenails are made of a protein called keratin, which is also found in our skin and hair. They protect the soft tissues beneath them and keep the tips of our toes safe. However, due to trauma, infection, or other reasons, we may lose a toenail. The good news is that toenails grow back, but it can take anywhere from 6 months to 2 years for them to completely regrow. During this time, it is important to take proper care of your feet to ensure that your toenail grows back strong and healthy. Here are some ways to help a toenail grow back quickly and maintain good foot care:
- Keep the wound dry and covered: Clean and dry your nail bed daily and cover it with a bandage. Change the bandage once a day to keep the area clean and protected.
- Apply a cold compress: Use a cold compress for up to 20 minutes to reduce swelling and inflammation. Wrap a cloth over an ice pack before applying it to your skin.
- Keep your nail elevated: Elevating your foot will reduce blood flow to the injury, which can help decrease swelling and bruising.
- Take biotin supplements: These supplements promote cell growth and help your body metabolize protein-building amino acids, contributing to faster nail growth.
- Maintain a balanced diet: A balanced diet ensures your body gets the necessary nutrients for nail growth.
- Treat any underlying infections: Fungal infections are common in toenails and can interfere with healthy regrowth. Treat any underlying infections to promote proper nail growth.
- Consult a podiatrist: If you have concerns about your toenail regrowth or want to explore safe restoration options, consult a podiatrist for personalized care and support.
Remember, each person's journey is unique, and patience is essential during the healing process. While you may not be able to dramatically accelerate nail growth, following these steps can support healthy regrowth and help you regain confidence in your toenails.

The impact of underlying conditions on toenail growth
Toenails are very slow-growing, with an average growth rate of 1.62mm per month. Toenail growth depends on attachment to the nail bed, and various factors can affect this growth. For example, if the toenail has fallen off, it cannot reattach and continue growing. Instead, a new nail must grow in its place, which can take anywhere from six months to two years.
Underlying conditions can impact toenail growth in several ways. Firstly, certain medical conditions can directly affect nail shape and growth patterns. For instance, nail-patella syndrome, a rare genetic condition, can cause underdeveloped or missing toenails. Similarly, leukonychia, a whitening of the nail plate, can be caused by inherited gene mutations or certain medical treatments.
Additionally, underlying conditions can create an environment that promotes toenail fungus, which can lead to nail detachment and growth abnormalities. For example, people with diabetes have an increased risk of fungal infections due to poor circulation in their feet. As people age, their nails become drier and more prone to cracking, allowing fungi to enter the nail bed.
Furthermore, specific toenail conditions can indicate underlying systemic diseases. For instance, pitting and increased nail thickness may suggest psoriasis, while concave nails that curve inward can indicate iron deficiency anaemia. Ingrown toenails, where the nail grows into the soft tissue, can be a sign of diabetes, peripheral vascular disease, or other circulatory issues.
In some cases, treating the underlying condition is necessary for proper toenail growth. For example, clubbed nails, which indicate underlying conditions such as heart or lung disease, require addressing the root cause for resolution. Similarly, addressing nutritional deficiencies or hormonal imbalances can promote healthier toenail growth. Overall, the impact of underlying conditions on toenail growth can be complex and varied, requiring proper diagnosis and treatment.

Toenail growth and the nail matrix
Toenails and fingernails protect your skin, but you might lose a nail due to trauma, fungus, or other reasons. Fungi can grow between your nail bed and toenail, eventually making your toenail fall off. Toenail fungus may appear as thick, yellow, cracked, or cloudy nails. In addition, as you age, your nails become dry and more likely to crack, allowing fungus to enter your nail bed.
Nail growth can slow down if you're sick or malnourished. Nails grow from underneath your skin at the matrix, which is the root of your nail. The nail matrix and the nail root are related. The matrix lies beneath the skin, at the inner edge of the nail plate, and is responsible for most of a nail's growth. It's where new cells grow and then advance forward to form the nail. The nail bed is also referred to as the sterile matrix, which extends from the edge of the nail root or lunula to the tissue known as the hyponychium. The germinal matrix, or nail matrix, creates new cells that become your fingernails or toenails. About 90% of nail growth comes from the germinal matrix, while the sterile matrix is responsible for keeping the nail attached to the underlying skin.
Injuries and certain health conditions can damage your nail matrix and interfere with nail growth. For example, chemotherapy and other medications can cause Beau's lines (horizontal ridges in your nails), slow nail growth, Mees' lines (white bands across your nails), and nail colour changes. A severe injury could cause your nail to fall off. Once your nail matrix heals, your nail will usually start to grow again. It may take several weeks before you see your new nail appear. In cases of severe nail matrix damage, some or all of your nail may not grow back.

Preventing toenail fungus
Toenail fungus can be challenging to treat and may lead to further infections if left untreated. Therefore, it is essential to take preventive measures to keep your toenails fungus-free. Here are some ways to prevent toenail fungus:
Keep Your Feet Clean and Dry
Wash your feet daily with soap and water, ensuring you dry them thoroughly, especially between your toes. Fungi thrive in warm, damp environments, so keeping your feet clean and dry can help prevent fungal growth.
Choose the Right Footwear and Socks
Select shoes made from breathable materials such as leather, canvas, or mesh. These materials allow airflow, helping to prevent excessive sweating. Avoid tight-fitting shoes that trap heat and moisture, creating an ideal environment for fungi. Additionally, opt for moisture-wicking socks that pull moisture away from your feet. Change your socks daily, and if they become sweaty, put on a fresh pair to avoid prolonged dampness.
Practice Good Nail Hygiene
Keep your toenails trimmed and short. Cut them straight across, ensuring they don't extend beyond the end of your toes. Avoid cutting them too short, as this can lead to ingrown toenails. Disinfect your nail clippers and other grooming tools after each use to prevent the spread of fungi. Wash the tools with soap and warm water, then disinfect them. Avoid sharing nail grooming tools, shoes, and socks with others to minimize the risk of transferring fungi.
Treat Athlete's Foot Promptly
Athlete's foot is a fungal infection that can spread to your toenails. If you notice symptoms like cracked, scaly, or peeling skin, itching, burning, or stinging between your toes, seek treatment immediately. Wash all your socks in hot water and detergent, and disinfect your shoes or consider replacing them to eliminate any remaining fungi.
Use Anti-Fungal Products
Apply over-the-counter anti-fungal creams to your toenails and the bottoms of your feet once or twice a week, especially if you've previously had toenail fungus. Use anti-fungal sprays in your shoes before wearing them to prevent fungal growth.
Regularly Inspect Your Feet and Toenails
Check your feet and toenails regularly for any changes in colour or texture, which could indicate the early stages of a fungal infection. If you notice any abnormalities, consult a doctor promptly for early treatment.
By following these preventive measures, you can significantly reduce the risk of toenail fungus and maintain healthy and fungus-free toenails.

Frequently asked questions
Nails grow from a process called keratinization, where cells multiply in the base of each nail and then layer on top of each other and harden. This process can be slowed down if you are sick, malnourished, or have an underlying condition.
While there is only so much you can do to speed up the process, you can take supplements that promote cell growth and help your body metabolize protein-building amino acids. You can also keep the wound dry and covered, and clean and moisturize the exposed nail bed.
In some cases, the nail matrix, which is the "factory" where your body makes new nails, can be permanently damaged, preventing the nail from growing back. This can happen due to injuries or certain health conditions.
