If Lines Start Appearing On Your Nails After 40, It Could Be A Warning Sign…
Have you noticed thin vertical lines running from the base to the tip of your fingernails as you’ve gotten older? If so, you’re not alone. Many people begin to spot these changes after the age of 40. Most of the time they’re harmless, but in some cases, they can signal underlying health issues. So, what causes vertical ridges—and when should you be concerned?\
Understanding Vertical Nail Ridges
Vertical ridges, also called longitudinal striations, are raised lines that extend from the cuticle to the nail tip. They can vary in depth and number and often become more noticeable with age.
Just like skin loses elasticity and hair turns gray, nails undergo structural changes over time. The production of keratin—the protein that forms nails—may slow down or become uneven, creating ridges.
Main Causes After Age 40
1. Natural Aging Process
The most common reason for vertical ridges is simply aging. As we get older, the body’s ability to regenerate skin cells slows down. The same happens to the nail matrix (the base of the nail), which may produce keratin unevenly, leading to ridges.
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.
 Bottom line: Vertical ridges after 40 are usually a natural part of aging. Still, paying attention to accompanying changes can help you catch potential health issues early.
