A black nail is usually the result of a subungual hematoma, which is when blood collects under the nail, causing it to turn purple or black. This can be due to a variety of reasons, including blunt force trauma, ill-fitting shoes, or bacterial infections. In most cases, the black nail will fall off a few weeks after it appears and can take anywhere from six months to two years to grow back. If you experience a black nail, it is important to monitor it and seek medical attention if necessary, especially if there is intense pain or the black coloration covers more than half of the nail.

Black nails are often caused by a subungual hematoma, which can be treated by draining the blood trapped under the nail
Black nails are typically caused by a subungual hematoma, which occurs when blood collects under the nail following an injury. This can cause the nail to separate from the nail bed and fall off. While small subungual hematomas (covering less than 25% of the nail bed) often require no intervention, larger hematomas may need to be drained to relieve pressure and prevent complications.
A subungual hematoma is usually the result of a direct trauma to the nail, such as a blow to the finger or toe, or catching the nail in a door or drawer. It can also be caused by repeated trauma, such as wearing ill-fitting shoes, or habits like nail biting. In some cases, certain systemic conditions, such as coagulopathy or anticoagulant therapy, can also predispose individuals to subungual hematomas.
To treat a subungual hematoma, the accumulated blood needs to be drained. This can be done by creating a small hole in the nail through which the blood can escape. At home, this can be achieved by heating a needle or the end of a paper clip until it is red-hot and then gently pushing it through the nail. However, some people may not feel comfortable performing this procedure at home and may prefer to seek treatment from a physician.
It is important to act quickly if you decide to drain a subungual hematoma, as the blood should be drained within 24 hours before it coagulates. Additionally, if the hematoma covers more than 50% of the nail, it is recommended to see a doctor, as they may need to remove the nail or repair any underlying lacerations.
While waiting for the nail to heal, it is important to keep the area clean and protected. This can be done by applying an antibiotic ointment and covering the nail with a bandage. If the nail falls off, it is important to protect the sensitive skin of the nail bed to prevent dryness and cracking, which can affect how the nail grows back.

Blunt force trauma, such as dropping something heavy on your foot, can cause a black nail
A black nail can be the result of blunt force trauma, such as dropping a heavy object on your foot. This type of injury is called a subungual hematoma, which is a fancy way of saying "blood under the nail". It occurs when blood vessels in the nail bed break, causing blood to pool and put pressure on the nail plate, resulting in pain and discolouration.
If you experience a blunt force injury that results in a black nail, it is important to monitor the situation and seek medical attention if necessary. In some cases, the nail may fall off on its own, but it is important to leave it alone and let the new nail grow underneath. You can cut down the injured nail, but do not pull it off. It is also important to keep the area clean and protected, as an infection can develop.
If there is a large amount of blood under the nail or if it is painful, you should see a doctor. They may recommend draining the blood with a needle to relieve the pressure. This procedure can be done in a medical office using a sterile needle or blade. It is important not to attempt this at home.
The time it takes for a black nail to fall off can vary depending on the severity of the injury and the size of the lost nail. It can take several weeks for the nail to completely fall off, and it may take a few months to a year for the nail to grow back. In some cases, it could take up to two years.
To reduce the risk of losing a nail in the future, it is recommended to keep your feet clean and your toenails smooth and short. You can also use silicon gel toe caps to help cushion your toes and prevent nail trauma.

A fungal infection can cause a black nail, especially in toenails due to socks and shoes providing a warm and moist breeding ground for fungus
A black nail can be caused by a variety of issues, including fungal infections. Fungal nail infections, known as onychomycosis, are a common condition that can cause nails to become brittle and discoloured. This is more likely to occur on toenails due to the warm and moist environment created by socks and shoes, providing an ideal breeding ground for fungi.
Fungi are microscopic organisms that can invade the toenail or fingernail, causing a fungal nail infection. This often starts at the edge of the nail and can spread to the entire nail, making it thicker and changing its colour to white, yellow, or black. The skin around the nail may become swollen and painful, and the nail may eventually lift off or detach from the nail bed.
Toenails are particularly susceptible to fungal infections due to the constant warmth and dampness created by wearing shoes for extended periods. Those who engage in activities that require prolonged shoe use, such as running or sports, are at a higher risk of developing fungal nail infections. Additionally, walking barefoot in places like gym showers, swimming pools, and locker rooms can increase the likelihood of contracting a fungal infection as these environments facilitate the spread of fungi.
To prevent and treat fungal nail infections, it is recommended to keep your feet clean and dry, wear shoes that fit properly, and avoid walking barefoot in high-risk areas. Over-the-counter antifungal treatments are available, but for more severe or persistent infections, it is advisable to consult a doctor. Oral antifungal medications may be prescribed for up to 6 months, depending on the type of infection. However, these medications can have side effects, and certain individuals with conditions like liver or kidney disease may not be suitable candidates for oral antifungal treatment.
It is important to note that black nails can also be caused by other factors such as trauma or injury. Blunt force or acute trauma can cause subungual hematoma, resulting in blood collecting under the nail and turning it black. In such cases, it is crucial to seek medical attention, especially if the nail is torn or lifted completely off the nail bed.

In rare cases, a black nail may be a symptom of melanoma, a form of skin cancer
A black nail is usually the result of a bruise or subungual hematoma, which occurs when blood collects under the injured nail. In rare cases, however, a black nail can be a symptom of melanoma, a form of skin cancer.
Melanoma of the nail unit is a rare type of skin cancer that occurs under the nails. It is known as subungual melanoma and is the deadliest form of skin cancer. It can develop under or around the fingernails and toenails, with the nail of the thumb or big toe being the most prevalent location. While anyone can develop subungual melanoma, it is more common in older individuals and people with skin of colour. A personal or family history of melanoma or previous nail trauma may also be risk factors.
The early signs of subungual melanoma can be challenging to detect, which makes it difficult to diagnose and treat early. The cancer often starts as a narrow brown to black pigmented band, visible on the length of a single nail plate, known as melanonychia. Over time, the pigment band typically becomes wider, especially at its proximal end, and the pigmentation becomes more irregular, with light and dark brown hues. It may also extend to involve the skin around the nail, known as the Hutchinson sign, a historical indicator of nail melanoma.
Other symptoms of subungual melanoma include streaks on the nails, colour changes in or around the nail, a bruise under the nail that does not heal, and the nail separating from the nail bed. The outlook for subungual melanoma depends on the stage at diagnosis and the individual's response to treatment. Early detection is crucial, as melanoma can rapidly spread to other organs without early treatment.

A detached toenail can take anywhere from a few months to two years to grow back, depending on the cause and size of the lost toenail
A black toenail is usually the result of a subungual hematoma, which occurs when blood collects under the nail, causing it to turn black or purple. This can be due to a blunt force injury, such as dropping something on the toe, or from repeated trauma, such as wearing ill-fitting shoes. In some cases, a black toenail may be caused by a fungal infection or, rarely, melanoma, a form of skin cancer.
If you have a black toenail, it is important to determine the underlying cause and seek medical attention if necessary. In many cases, the discolouration will disappear as the nail grows out, which can take a few weeks to several months. However, if the nail begins to detach from the nail bed, it is important to see a doctor.
A detached toenail will typically grow back within a year to a year and a half. However, depending on the cause and size of the lost toenail, it could take up to two years. In some cases, surgery may be required to remove the nail and stop it from growing back. To ensure the nail grows back properly, it is important to keep the nail bed clean and protected.
If the black toenail is due to a fungal infection, there are over-the-counter creams and ointments that can be used to treat the infection. However, if the infection does not clear up after a few days, it is important to consult a doctor.
In summary, a detached toenail can take anywhere from a few months to two years to grow back, depending on the underlying cause and the size of the lost toenail. It is important to seek medical attention if the nail is painful, if there is bleeding, or if there are signs of infection.
