What You'll Learn

Clean the wound with soap and water
If you've cut your fingernail, it's important to clean the wound with soap and water to prevent infection. First, elevate your finger above your heart to slow the bleeding. If there's a lot of blood, apply gentle pressure with a clean cloth or bandage.
Once the bleeding has slowed, you can start to clean the wound. Use soap and warm water to gently wipe away any blood or dirt from the wound. Be sure to clean your hands before touching the wound to prevent infection. If the wound is dirty, rinse it with clean water, but do not scrub as this may cause further damage.
After cleaning the wound, apply an antibiotic ointment to the affected area to further prevent infection. Then, cover the wound with a sterile bandage or adhesive dressing. If the cut is on your dominant hand, you may find it easier to use a band-aid or other self-adhesive dressing.
If the cut is severe or continues to bleed heavily after following these steps, seek medical attention.

Elevate the finger to stop bleeding
Elevating your injured finger above your heart is a critical step in treating a bleeding cut on your finger. This is because raising the wound helps to slow and eventually stop the bleeding. It also reduces swelling and boosts your chances of keeping a simple cut from causing further medical complications.
To elevate your finger, you can allow your hand or arm to rest on something, such as a table or a stack of pillows, so that the injured finger is raised above the level of your heart. This position should be maintained until the bleeding stops, which should take a few minutes at most for a minor cut.
If you are experiencing throbbing pain, elevation can also help alleviate this. Keeping your finger elevated will also be useful after the bleeding has stopped, as it will help the cut start to heal.
It is important to note that elevating your finger is just one step in treating a bleeding cut on your finger. Other steps include cleaning the wound and applying gentle pressure with a clean cloth or bandage. If the cut is minor, you can then leave it uncovered or apply an adhesive dressing, such as a Band-Aid, to keep the wound clean. However, if the cut is more severe or shows signs of infection, you should seek medical attention.

Apply pressure to the wound
If you have a cut fingernail, it is important to apply pressure to the wound to stop the bleeding. This is a crucial step in treating a cut finger and will also give you a clearer sense of how deep the cut is. Minor cuts and scrapes that are oozing a little blood usually don't require any bleeding control, but applying pressure can help stop the bleeding more quickly. If the bleeding is heavy, bright red, or spurting, you should take steps to control it by applying gentle pressure with a clean cloth, gauze, or towel. You can also use a bandage or a t-shirt to apply pressure to the wound. Remember to elevate the injured finger above the level of your heart as you apply pressure, as this will help with the throbbing and bleeding.
It is important to note that if the bleeding does not stop after 15 minutes of applying pressure, or if the cut is deep, gaping, or longer than 1/4 inch, you should seek medical attention. Do not try to treat deep or long cuts at home, as they may require stitches or other medical procedures. Additionally, if you see any damage to the tendons, ligaments, or bone, it is important to seek professional medical help.
Once the bleeding is under control, you can move on to the next steps of treating a cut fingernail, which may include cleaning the wound, covering it with a bandage, and seeking further medical attention if necessary.

Cover the wound with a bandage
Covering a cut fingernail wound with a bandage is an important step in the healing process. It helps protect the wound from infection and external contaminants and also provides support to the injured area.
Before applying a bandage, it is important to clean the wound. This can be done by gently wiping away any blood or dirt with water. If there is a lot of blood, you can use a clean cloth or bandage to apply pressure to the wound and stop the bleeding. Once the bleeding has stopped, you may proceed to clean the wound. Avoid scrubbing the wound, as this may cause further damage. Instead, gently rinse it with clean water.
When selecting a bandage, it is important to choose one that is sterile and compressive. Adhesive dressings are ideal for covering cut fingernail wounds. They are designed to adhere securely to the skin around the wound, providing protection and support. Ensure that the bandage is not wrapped too tightly, as this can restrict blood flow to the finger.
If the cut is deep or wide, it may require stitches. In such cases, a healthcare professional should be consulted, and they may use strong, sterile adhesive strips or stitches to close the wound. For more serious injuries, such as a severed finger, it is crucial to seek emergency medical attention.

Seek medical attention if deep or infected
Fingernail injuries can be quite common, and many can be treated at home. However, if a cut fingernail is deep or infected, it is important to seek medical attention to prevent complications and ensure proper healing.
Deep cuts may reveal deeper layers of skin, fat, or bone. Such injuries may require stitches or even a skin graft if there is extensive skin damage. If you believe a cut is too deep to be treated at home, it is recommended to go to an emergency room or urgent care clinic. A healthcare professional will be able to assess the severity of the wound and determine the appropriate treatment.
Infection is a serious complication of any wound, and fingernail cuts are no exception. Fingernails are particularly susceptible to infection due to their proximity to many bacteria and the difficulty in keeping them clean. If a cut fingernail becomes infected, seek medical attention promptly. Antibiotics may be necessary to clear the infection and prevent further complications.
In addition to depth and infection, there are other signs that indicate the need for medical attention. If there is any injury to the ligaments, tendons, or nerves in the finger, medical help is required. Furthermore, if there is any concern about a bleeding disorder or if the wound is not healing properly, it is important to consult a healthcare professional. For individuals with certain health conditions, such as diabetes or poor circulation, seeking medical attention for any fingernail injury is generally advised.
