What Do Vertical Ridges on Your Nails Mean After 40?

Noticing thin vertical lines on your nails as you age? You’re not alone. These ridges—called longitudinal striations—are usually harmless and a common part of getting older.

As we age, keratin production in the nail matrix slows or becomes uneven, leading to these texture changes.

Main Causes:

• Natural aging: Slower cell turnover affects nail structure.
• Dehydration: Dry nails from age, soaps, or chemicals can make ridges more visible.
• Nutrient deficiencies: Low biotin, iron, or zinc levels can weaken nails.
• Health conditions: Sometimes, ridges can be linked to thyroid issues, circulation problems, or arthritis.

When to See a Doctor:
If ridges come with discoloration, thickening, pain, or swelling, seek medical advice. These signs could indicate infections or, rarely, melanoma.

Care Tips:

• Stay hydrated and moisturize your nails regularly.
• Eat a nutrient-rich diet to support nail health.
• Use gentle nail care tools.
• Talk to your doctor about biotin supplements if needed.
