Vertical ridges are usually harmless, but you should seek medical attention if you notice:
-
Changes in nail color (especially dark streaks or lines)
-
Splitting, peeling, or thickening nails
-
Pain, swelling, or inflammation around the nail
These may point to fungal infections, trauma, or—in rare cases—melanoma, a serious form of skin cancer that can appear under the nail.
How to Care for Aging Nails
Here are some simple tips to reduce the appearance of ridges and keep your nails strong and healthy:
-
Moisturize regularly with hand and nail cream, especially after washing your hands.
-
Stay hydrated, since dry nails are more prone to ridges and breakage.
-
Eat a nutrient-rich diet with vitamins A, C, B-complex, and minerals like zinc and iron.
-
Use gentle nail care tools and avoid harsh manicures or over-filing.
-
Consider biotin supplements—but always consult a healthcare provider first.
