Will My Uneven Toenail Improve After Injury and Treatment? - Dermatology

Uneven nails?


Hello, doctor.
Previously, I injured my toenail, which resulted in bruising and partial detachment.
A dermatologist used a laser to create two small holes to drain the blood (without removing the nail).
In the past two days, the original nail has fallen off, and I noticed that the newly grown nail is thinner and uneven.
Will this improve? Thank you.

Hello: Currently, it is advisable to avoid any further external injuries.
If the nail matrix is not damaged, it should gradually return to normal.
If there are any abnormalities with the nail, please consult a dermatologist for diagnosis and treatment.
Thank you!

More Info


After experiencing an injury to your toenail, it's understandable to be concerned about the appearance and health of the nail as it grows back. Based on your description, it seems that you have undergone a procedure to relieve the pressure from the hematoma (the collection of blood under the nail) by creating small openings in the nail bed. This is a common and effective treatment for such injuries.

When a toenail is injured, several things can happen. The nail may become discolored, and in some cases, it may partially or completely detach from the nail bed. The new nail that grows back can sometimes appear different from the original nail, as you have noticed with the new nail being thinner and uneven. This is not uncommon and can be attributed to several factors:
1. Nail Growth Cycle: Toenails grow at a slower rate compared to fingernails, typically about 1 millimeter per month. After an injury, it may take several months for the nail to fully grow out and for any abnormalities to resolve. The new nail may initially appear thinner and uneven as it grows in.

2. Nail Bed Health: The health of the nail bed plays a crucial role in the appearance of the new nail. If the nail bed was damaged during the injury, it could affect how the new nail forms. The presence of any residual trauma or inflammation can also impact nail growth.

3. Nutritional Factors: Proper nutrition is essential for healthy nail growth. Ensure you are consuming a balanced diet rich in vitamins and minerals, particularly biotin, zinc, and protein, which are known to support nail health.

4. Time and Care: With time, many nail injuries improve as the new nail continues to grow out. It's important to keep the area clean and protected. Avoiding trauma to the nail during the healing process is crucial. If the nail continues to grow in an abnormal shape or if you experience pain, it may be worth consulting a dermatologist or a podiatrist for further evaluation.

5. Potential Treatments: If the new nail does not improve over time or if you have concerns about its appearance, there are treatments available. These can include topical treatments to strengthen the nail, or in some cases, surgical options to correct any underlying issues.

In summary, while it is common for a new toenail to appear different after an injury, many cases improve with time as the nail continues to grow. Keep monitoring the situation, and if you have any concerns about pain, infection, or persistent abnormalities, do not hesitate to seek professional medical advice. Regular follow-ups with a healthcare provider can ensure that your toenail heals properly and that any necessary interventions are made in a timely manner.
