The good news? In most cases, they’re harmless. But sometimes, these changes in your nails can be signs of deeper issues. Let’s take a closer look at why they happen, what they could mean, and how to care for aging nails to keep them strong and healthy.
What Are Vertical Nail Ridges?
Vertical ridges, also known as longitudinal striations, are raised lines that run from the cuticle (the base of the nail) to the tip. Some ridges are barely noticeable, while others can be felt clearly when you run your finger across the nail.
It’s a natural part of the body’s aging process. Just as skin starts to show wrinkles and hair begins to gray, the texture and structure of our nails also begin to change. Over time, the cells that form your nails — known as keratin-producing cells — may slow down or become uneven in their growth. This results in changes to how smooth your nails look and feel.
