How to Get Rid of a Black Toenail: Causes, Treatments, and Prevention

A black toenail can be alarming — especially when you don’t remember hurting your foot. It may appear dark brown, purple, or completely black, and often signals trauma, infection, or other nail issues. While some cases heal on their own, others need medical attention. This article explains what causes black toenails, how to treat them safely, and how to prevent them from coming back.

Understanding Black Toenails

A black toenail is usually a sign that something has gone wrong under the nail — often bleeding, bruising, or fungal buildup. It can affect anyone, but is more common among:

• Runners and athletes

• People who wear tight shoes

• Those with diabetes or poor circulation

• People who frequently get pedicures or use harsh nail products

The black color forms when blood, dead skin cells, or pigment changes occur under the nail plate. Sometimes, the discoloration can spread or lift the nail if not treated properly.

Common Causes of Black Toenails

1. Trauma or Injury

The most frequent cause of black toenails is trauma. Stubbing your toe, dropping something heavy on it, or constant rubbing from tight shoes can damage blood vessels beneath the nail. This causes a subungual hematoma — a buildup of blood that looks dark or black under the nail.

Symptoms:

• Pain and throbbing under the nail

• Swelling or tenderness

• The nail may loosen over time

2. Fungal Infections

Fungal infections can cause toenails to become thick, brittle, and dark-colored. The black shade may come from debris, fungus buildup, or dead tissue under the nail.

Symptoms:

• Discolored (yellow, brown, or black) nail

• Foul odor

• Nail thickening or crumbling

• Itchiness around the nail bed

3. Tight Footwear

Shoes that are too small or narrow can repeatedly press the toenail against the shoe, cutting off circulation and leading to bruising or bleeding under the nail.

4. Medical Conditions

In rare cases, black toenails may indicate melanoma, a serious skin cancer. If the black line or spot doesn’t grow out with the nail, or if it changes shape, color, or causes pain, it’s vital to see a doctor immediately.

Treatment for a Black Toenail

1. For Minor Bruising or Injury

If your black toenail is caused by a small injury and the pain is mild, it will usually heal on its own within a few weeks.

What to do:

• Rest and elevate your foot to reduce swelling.

• Apply an ice pack for 10–15 minutes several times a day.

• Wear open-toed or loose shoes to avoid pressure.

• Keep the nail clean and dry.

As the nail grows, the black area will move upward and eventually be trimmed away.

2. For Severe Pain or Large Blood Clots

If blood is trapped under the nail and causing pressure or throbbing, a doctor may perform a drainage procedure. This involves making a small hole in the nail to release blood and relieve pain. Never attempt to do this at home — it requires sterile tools and professional care.

3. For Fungal Infections

If a fungus is the cause:

• Use antifungal creams or medicated nail lacquers (available over-the-counter).

• In stubborn cases, your doctor may prescribe oral antifungal medication.

• Trim and file the affected nail regularly.

• Keep feet clean and dry, and wear breathable shoes.

4. If the Nail Falls Off

In some severe injuries, the nail may loosen and fall off. This can look scary but usually isn’t dangerous if treated properly.

• Clean the exposed area gently with warm water and antiseptic.

• Cover with a sterile bandage.

• Avoid picking or scraping the area.

• The new nail will begin growing within a few weeks.

5. When to See a Doctor

• Pain is severe or worsening.

• The discoloration spreads or deepens.

• There’s pus, foul odor, or signs of infection.

• You have diabetes or poor circulation.

• You notice a black streak that doesn’t move with nail growth (possible melanoma).

Home Remedies for Mild Black Toenails

• Epsom Salt Soak: Mix warm water and Epsom salt to reduce inflammation and promote healing.

• Tea Tree Oil: Has natural antifungal and antibacterial properties. Apply diluted tea tree oil to the nail twice daily.

• Apple Cider Vinegar: Soak your foot in a mix of equal parts vinegar and water for 10–15 minutes a day to fight fungus.

• Aloe Vera Gel: Helps soothe pain and promote skin recovery.

Always patch-test natural remedies before applying them widely to avoid irritation.

Prevention Tips

1. Trim nails straight across — avoid cutting them too short.

2. Wear well-fitting shoes — especially if you run or walk long distances.

3. Keep feet dry and clean — moisture encourages fungal growth.

4. Use antifungal powder or spray — especially in humid climates.

5. Avoid sharing nail clippers or foot tools.

6. Choose breathable socks and shoes.

If you exercise regularly, check your feet often for bruising, discoloration, or signs of infection.

Final Thoughts

A black toenail might look alarming, but most cases are treatable with rest, hygiene, and proper foot care. The key is identifying the cause early — whether it’s an injury, fungus, or something more serious — and treating it correctly. Don’t ignore a black toenail that’s painful, persistent, or changing in appearance. With timely care and prevention, your toenails can return to their normal, healthy state.
