New fingernail growing under old nail
The fascinating world of nail growth!
It's not uncommon for a new fingernail to grow underneath an old one, a process called "nail plate separation" or "nail plate splitting." This can occur for several reasons:
- Nail growth rate: Fingernails grow at an average rate of 0.1 to 0.2 millimeters per day, or about 1 to 2 centimeters (0.4 to 0.8 inches) per month. If the new nail grows faster than the old one, it can push the old nail back, causing it to lift and separate.
- Nail plate thickness: If the new nail plate is thicker or more compact than the old one, it can exert pressure on the old nail, causing it to lift and separate.
- Nail bed changes: Changes in the nail bed, such as inflammation, injury, or infection, can cause the nail plate to lift and separate.
- Genetic predisposition: Some people may be more prone to nail plate separation due to their genetic makeup.
When a new nail grows underneath an old one, it can cause a few issues:
- Discomfort: The lifting nail can cause discomfort, especially if it's accompanied by inflammation or irritation.
- Aesthetics: The separated nail can be unsightly, especially if it's noticeable.
- Risk of infection: If the separated nail is not properly cared for, it can increase the risk of infection.
To manage nail plate separation, you can try the following:
- Keep your nails clean and dry: Wash your hands regularly, especially after activities that cause dirt or moisture to accumulate under your nails.
- Trim your nails carefully: Trim your nails straight across or slightly rounded, with nails filed smooth to prevent snagging or catching on clothing.
- Use a nail file: Gently file the lifted nail to smooth out any ridges or imperfections.
- Apply a nail strengthener: Nail strengtheners can help fortify your nails and reduce the likelihood of separation.
- Consult a doctor or dermatologist: If you experience persistent discomfort, pain, or signs of infection, consult a healthcare professional for further guidance.
Remember, nail plate separation is a common phenomenon, and with proper care and attention, you can manage the issue and maintain healthy, beautiful nails.
