Toenails can fall off or become damaged for a variety of reasons, including trauma, fungal infections, and medical conditions. Toenail regrowth is a slow process, typically taking anywhere from 6 months to 2 years. Several factors can influence the rate of regrowth, including age, overall health, nutrition, exercise, and circulation. In some rare cases, severe trauma or damage to the nail matrix may result in the nail not growing back at all. Proper care and professional medical treatment are crucial for ensuring healthy toenail regrowth.

What You'll Learn
Toenail trauma
Causes of Toenail Trauma:
- Stubbing your toe
- Dropping a heavy object on your foot
- Wearing ill-fitting shoes that cause repeated pressure or friction on the toe
- Sports or athletic activities that involve frequent running or hiking can lead to "runner's toe," a condition caused by repeated strain on the nail.
- Medical conditions such as diabetes can affect nail health and increase the risk of infections, which can impact toenail growth.
- Fungal infections can cause the nail to become thick, yellow, cracked, or cloudy, eventually leading to nail separation and loss.
Symptoms and Complications:
- Blood pooling under the nail, known as a subungual hematoma, which can cause the nail to appear red, black, blue, or purple.
- Pain and discomfort.
- The nail may tear, split, or fall off completely.
- Ingrown toenails can occur due to trauma or improper nail care.
- In some cases, the nail may grow back misshapen or with ridges and grooves, indicating possible damage to the nail matrix.
Treatment and Prevention:
Proper care and treatment of toenail trauma are essential for promoting healing and preventing further complications:
- Minor injuries can often be managed at home by cleaning and protecting the affected area.
- If bleeding occurs under the nail, it is crucial to seek medical attention, especially if it covers more than half of the nail area, as it could indicate a more severe injury or underlying condition.
- In severe cases, medical treatments such as nail trephination may be necessary to drain the blood and relieve pressure under the nail.
- To prevent toenail trauma, it is recommended to wear properly fitted shoes and avoid ill-fitting footwear that can cause repeated pressure on the toes.
- Silicone or gel toe caps can also help prevent blisters, rubbing, and irritation that could lead to toenail trauma.
Regrowth and Recovery:
The regrowth process for toenails typically takes between 6 months to a year, but it can vary depending on individual factors such as age, health, and the type of injury:
- Younger individuals tend to have faster nail growth than older adults.
- Good nutrition, exercise, and overall health can positively influence nail regrowth speed.
- In some rare cases, severe trauma or damage to the nail matrix may result in permanent nail loss or misshapen regrowth.
- Proper care and professional medical assistance can significantly impact the recovery process and promote healthy nail regrowth.

Fungal infections
Toenail fungus, or onychomycosis, is a common issue that affects many people. It occurs when fungi infect the area underneath the nail surface, causing a noticeable change in the toenail's appearance and structure. While fungal infections can affect both fingernails and toenails, toenails are particularly vulnerable due to the warm and damp environments that fungi thrive in, such as swimming pools, locker rooms, and showers.
Toenail fungus typically results in cosmetic changes to the nail, including discolouration, thickening, and deformity. The nail may appear darker or yellow, with white markings or cracks on the surface. As the infection progresses, the nail can become thicker and more brittle, making it challenging to trim and causing discomfort when wearing shoes. In some cases, the infection can spread beyond the nail, affecting other toenails, the surrounding skin, or even the fingernails. Additionally, secondary bacterial or yeast infections may develop in or around the nail plate.
To prevent fungal infections and promote healthy toenail growth, it is crucial to practice good foot hygiene and nail care. This includes clipping toenails straight across, ensuring they do not extend beyond the tip of the toe. Wearing well-fitting shoes made of breathable materials and avoiding tight hosiery can help reduce moisture and create an unfavourable environment for fungi. Additionally, choosing synthetic socks that wick moisture away from the feet is beneficial. Disinfecting nail care tools and avoiding nail polish on infected nails can also help prevent the spread of infection.
If you are experiencing issues with toenail growth due to a previous fungal infection, it is important to address the underlying cause effectively. This may involve seeking medical advice from a podiatrist or a specialist in foot health, such as Shuman Podiatry & Sports Medicine. They can provide guidance on proper treatment and care to ensure that your toenail grows back healthy and strong. In some cases, antifungal treatments may be necessary to promote the growth of a healthy new nail.

Medical conditions
Toenails are susceptible to various medical conditions that can affect their growth and appearance. Here are some of the most common medical conditions related to toenail issues:
Fungal Infections
Fungal infections are a common issue affecting toenails. Fungi thrive in warm, wet environments, and shoes and socks provide the perfect conditions for their growth. Symptoms of a fungal infection include thick, yellow, cracked, or cloudy nails. Fungal infections can cause the nail to become brittle and eventually lead to nail separation and loss. In severe cases, surgical removal of the nail may be necessary, followed by a regrowth period of up to 18 months.
Diabetes
Diabetes is a medical condition that can impact nail health and growth. People with diabetes may experience slower nail growth and an increased risk of infections. Poor circulation associated with diabetes can also delay the toenail regrowth process. Proper management of diabetes is crucial to maintaining nail health and promoting healthy nail regrowth.
Psoriasis
Psoriasis is a skin condition that can also affect the nails. It causes itchy, scaly patches on the skin and can lead to nail changes. Medications such as corticosteroids, biologics, and topical steroids may improve nail appearance and promote healthy regrowth in individuals with psoriasis.
Heart Attack, COVID-19, Pneumonia
Serious health events or illnesses, such as a heart attack, COVID-19, or pneumonia, can interrupt nail growth and cause Beau's lines, which are horizontal ridges in the nails. These conditions can affect the nail matrix, leading to temporary changes in nail appearance and growth.
Cancer
Subungual melanoma is a type of cancer that affects the nail matrix. It requires surgical removal, and further treatments such as chemotherapy or radiation may be necessary if the cancer has spread. Chemotherapy medications can also temporarily affect the nail matrix, causing Beau's lines or slow nail growth.
It is important to consult a healthcare professional if you are experiencing toenail issues related to any medical condition. Proper diagnosis and treatment can help manage symptoms and promote healthy nail regrowth.

Vascular conditions
If you've ever had a toenail injury, you may have noticed that your toenail isn't growing back properly. Several factors can contribute to this, including vascular conditions that affect blood flow to the area. Good blood circulation is essential for nail growth and health. Here are some vascular conditions that might be preventing your toenail from growing back properly:
Peripheral Artery Disease (PAD): PAD is a condition that affects the blood flow to your limbs, especially your legs and feet. It is caused by a buildup of plaque in the arteries, narrowing or blocking them and restricting blood flow. When this happens, the reduced blood flow can slow down or stop nail growth. People with PAD often experience hair loss on their legs and feet, as well as slow nail growth.
Raynaud's Disease: Raynaud's disease is a rare vascular disorder that affects blood flow to the extremities, including the toes. It causes the blood vessels in the toes to narrow, limiting blood supply. During episodes of vasospasm, the toes may turn white or blue due to reduced blood flow. This interruption in circulation can affect nail growth, leading to ridges, brittleness, or slow growth.
Diabetic Peripheral Angiopathy: Diabetes can lead to complications in the blood vessels, causing a form of peripheral vascular disease known as diabetic peripheral angiopathy. High blood sugar levels can damage blood vessels and affect their ability to supply oxygen and nutrients to the nails. As a result, toenails may grow more slowly or become thickened and discolored.
Deep Vein Thrombosis (DVT): DVT is a condition where a blood clot forms in one of the deep veins of your body, usually in the legs. While DVT itself does not directly affect nail growth, the condition can lead to a more serious complication called a pulmonary embolism, which impacts blood flow and oxygenation, thereby affecting nail health.
To manage and treat these vascular conditions, it is important to consult a healthcare professional. They can provide guidance on improving blood circulation, managing symptoms, and promoting nail health. In some cases, medical interventions may be necessary to restore proper blood flow and support the growth of your toenails.

Nail matrix damage
The nail matrix is the "factory" where your body makes new nails. Located at the base of the nail, it creates new cells that allow your nail to grow. Your nail may stop growing if the nail bed is injured. The matrix creates new skin cells, pushing out the old, dead skin cells to make your nails. As a result, injuries to the nail bed or disorders that affect the matrix can affect your nail growth.
Injuries and certain health conditions can damage your nail matrix and interfere with nail growth. Minor damage to your nail matrix can temporarily change your nail's appearance. For example, you might notice a change in how your nail feels to the touch. A severe injury could cause your nail to fall off. Toenail fungus may appear as thick, yellow, cracked or cloudy nails. Illnesses, such as a heart attack, COVID-19, or pneumonia, can interrupt new nail growth and cause Beau's lines (horizontal ridges in your nails).
In cases of severe nail matrix damage, some or all of your nail may not grow back. This is rare and typically occurs in severe trauma cases, such as crushing injuries or deep cuts. However, with the right treatment, you can often see healthy nails grow again. Even if your nail falls off, it usually grows back with proper medical care.
After an injury, it's common for nails to show temporary changes as they heal, such as bruising, ridges, or a rough surface. These typically resolve over time as the damaged nail grows, allowing new, healthy cells to replace the affected area. Depending on the rate of your nail growth, this can take several months for fingernails and even longer for toenails.
If you have sustained nail trauma, it is important to seek help from a skilled practitioner, such as a board-certified dermatologist. They can help you determine the best course of treatment to restore nail health and protect your nails from future trauma.
