- Underlying Health Conditions
Occasionally, vertical ridges can be linked to health issues such as poor circulation, thyroid imbalances, or rheumatoid arthritis. If you notice additional symptoms like fatigue, brittle hair, or skin changes, consider speaking with a healthcare provider.
When to See a Doctor
Vertical ridges are generally harmless. However, you should seek medical advice if you notice:
- Changes in nail color (especially dark streaks)
- Splitting, peeling, or thickened nails
- Pain, swelling, or redness around the nail
These signs could indicate fungal infections, trauma, or—rarely—melanoma, a serious form of skin cancer.
How to Keep Nails Healthy
- Moisturize: Apply hand and nail cream regularly, especially after washing your hands.
- Stay hydrated: Dry nails are more prone to ridges and breakage.
- Eat a balanced diet: Include vitamins A, C, B-complex, and minerals like zinc and iron.
- Gentle nail care: Avoid harsh manicures, over-filing, or aggressive nail treatments.
- Consider supplements: Biotin may help strengthen nails—but check with your doctor first.
Vertical ridges after 40 are usually a normal part of aging. Paying attention to additional changes can help you identify potential health issues early. Healthy nails often reflect a healthy body—so treat them with care!
