What Causes My Toenail to Turn Black? Exploring the Common Causes of Discolored Toenails

Toenails that have turned black can be a cause for concern. While there are many potential causes of discolored toenails, some of the most common include fungal infections, trauma, and certain medical conditions.

Fungal infections are one of the most common causes of black toenails. Fungal infections of the toenail, also known as onychomycosis, can cause the nail to become thick, brittle, and discolored. The fungus can enter the nail through a small cut or crack in the skin, and can be spread from person to person. Treatment for fungal infections of the toenail typically involves antifungal medications.

Trauma to the toenail can also cause it to turn black. This can occur when the toenail is crushed or when the nail bed is injured. In some cases, the nail may turn black due to a hematoma, which is a collection of blood under the nail. Treatment for a black toenail due to trauma typically involves protecting the nail from further injury and allowing it to heal.

Certain medical conditions can also cause the toenail to turn black. These conditions include psoriasis, diabetes, and peripheral vascular disease. In some cases, the discoloration may be due to a lack of blood flow to the nail. Treatment for these conditions typically involves managing the underlying condition and protecting the nail from further injury.

In some cases, the cause of a black toenail may not be immediately apparent. If the discoloration does not improve with home care, it is important to seek medical attention. A doctor can help to determine the cause of the discoloration and provide appropriate treatment.

Taking Care of Your Toenails: Tips for Treating and Preventing Black Toenails

Black toenails, also known as subungual hematomas, are a common condition that can be caused by a variety of factors, including trauma, infection, and even wearing ill-fitting shoes. While they are usually not serious, they can be painful and unsightly. Fortunately, there are several steps you can take to treat and prevent black toenails.


If you have a black toenail, the first step is to determine the cause. If it is due to trauma, such as stubbing your toe, you may need to seek medical attention. If the cause is infection, your doctor may prescribe antibiotics.

If the cause is ill-fitting shoes, you should switch to a more comfortable pair. You may also want to consider wearing open-toed shoes or sandals to allow your toenail to breathe.

If the black toenail is due to a fungal infection, your doctor may prescribe an antifungal medication. You may also need to trim the nail and apply an antifungal cream.


The best way to prevent black toenails is to wear shoes that fit properly. Shoes that are too tight or too loose can cause trauma to the toenail, leading to a black toenail.

You should also keep your toenails trimmed and filed. Long toenails can be more prone to trauma and infection.

Finally, it is important to keep your feet clean and dry. Fungal infections thrive in warm, moist environments, so it is important to keep your feet dry and clean.

By following these tips, you can help prevent and treat black toenails. If you have any concerns, it is best to speak to your doctor.
