What Those Vertical Ridges on Your Fingernails Might Be Telling You — Especially After 40
Why You Might Have Vertical Ridges on Your Fingernails If you’ve noticed faint or deep vertical lines running from the base to the tip of your nails, you’re not alone. These are called vertical nail ridges, and they often become more visible with age—especially after 40. What Causes Them?
- Aging: As we age, our nail growth slows and becomes uneven, leading to ridges—similar to how our skin wrinkles.
- Dryness: Aging skin and nails lose moisture, making ridges more noticeable. Frequent handwashing and harsh soaps can worsen this.
- Nutrient Deficiencies: Low levels of biotin, iron, zinc, or magnesium can affect nail health.
- Health Conditions: In rare cases, ridges can signal issues like poor circulation, thyroid problems, or arthritis.
When to See a Doctor
Seek medical advice if you notice:
- Black or dark brown streaks
- Pain, swelling, or redness
- Nail thickening, peeling, or splitting
These could point to infection or, in rare cases, skin cancer under the nail.
How to Care for Aging Nails
- Moisturize regularly with nail oils or hand creams.
- Stay hydrated to keep nails flexible.
- Eat a nutrient-rich diet with biotin, zinc, and iron.
- Be gentle—avoid over-filing and harsh nail products.
- Use gloves when cleaning or gardening to protect your nails.
Vertical ridges are usually harmless and part of aging—but they can also reflect changes in your overall health. If you’re unsure, ask your doctor.
