Ever glanced down at your nails and noticed faint vertical lines running from the cuticle to the tip? You’re not alone—and if you’re over 40, those little ridges might be showing up more than they used to.
The good news? In most cases, they’re completely harmless. These vertical ridges, also called longitudinal striations, are usually just a sign that your body is changing with age. Still, they can sometimes offer helpful clues about what’s going on beneath the surface—especially when it comes to your health, hydration, and nutrition.
So, What Causes Them?
The most common reason? Your body is simply producing less keratin than it used to. Keratin is the protein that gives your nails strength and structure, and like many things, it tends to slow down with age. The result: a less smooth surface and a more ridged texture.
Dryness can also make these ridges more noticeable. As we age, our skin and nails naturally lose moisture, and frequent handwashing or exposure to harsh cleaning products can make things worse. Dry nails are more brittle, and that brittleness can show up as lines and ridges.
Could It Be a Nutritional Deficiency?
Possibly. As we get older, our bodies may not absorb nutrients as efficiently, and that can subtly affect our nails. A few key vitamins and minerals play a big role in nail health, including:
Biotin (Vitamin B7): Helps build keratin
Iron: Carries oxygen to the nail bed
Magnesium: Supports healthy cell function
Zinc: Aids in tissue repair and growth
If your diet is lacking in these, your nails may start to look or feel a bit off—more brittle, more ridged, or just not as healthy as they used to be.
When It Might Be Something More
Most of the time, vertical ridges are just cosmetic. But if you notice other changes—like odd colors, crumbling edges, or swelling around the nail—it might be worth checking in with a doctor. In rare cases, nail changes can be linked to things like thyroid issues, circulation problems, or autoimmune conditions.
Red flags to watch for:
Yellow, blue, or brown discoloration
Nails that thicken, split, or break easily
Redness or tenderness around the nail
Sudden or dramatic changes in texture
