Noticed fine vertical ridges running from the base to the tip of your nails? If you’re over 40, you’re not alone—and these subtle nail changes could be more meaningful than you think.
These ridges, known as longitudinal striations, are often just a natural part of aging. Just like skin and hair, your nails go through changes over time. One of the main culprits? A slowdown in keratin production, the protein responsible for strong, smooth nails. As production dips with age, nails can become drier and more uneven in texture.
Daily exposure to water, soap, and harsh cleaning products can make the dryness worse, highlighting these ridges even more. Plus, as we age, our bodies absorb nutrients less efficiently. A lack of biotin, iron, magnesium, or zinc may make nails weaker and more prone to ridging.
Usually, these lines are harmless. But in some cases, they might hint at an underlying health issue—such as poor circulation, thyroid imbalances, or even early signs of rheumatoid arthritis. If you also notice nail discoloration, thickening, splitting, pain, or swelling around the nail bed, it’s best to get it checked by a healthcare professional.
How to Keep Your Nails Healthy After 40:
-
Moisturize your hands and nails regularly
-
Stay hydrated to help maintain elasticity and moisture
-
Eat a balanced diet rich in nail-friendly nutrients
-
Consider biotin supplements—but only with medical guidance
-
Avoid harsh chemicals and handle your nails gently
While vertical nail ridges are typically nothing to worry about, sudden changes in nail appearance should never be ignored. Sometimes, your nails really do speak louder than words.
