How do you care for aging nails?

While ridges can be a part of aging, there are several ways to care for your nails to  minimize their appearance  and improve their overall strength:

1.  Hydrate regularly

Use a  hand cream  or  nail oil  rich in ingredients like  vitamin E  or  shea butter  , especially after washing your hands or using cleaning products.

2.  Stay hydrated

Drinking enough water is essential for healthy nails. Dried nails are more prone to brittleness and visible ridges.

3.  Focus on nutrition

Eat a  balanced diet  with a variety of fruits, vegetables, lean proteins, and whole grains. Pay special attention to:

  • Vitamin A and C  (for healthy nail cells)
  • Biotin  (found in eggs, nuts, and whole grains)
  • Zinc and iron  (found in leafy greens, legumes and meat)

Talk to your doctor before starting any supplements, especially if you are already taking medications.

4.  Be careful with your nails

Avoid rough manicures and don’t file your nails too aggressively. Buffing can help smooth out ridges, but overdoing it can thin the nail and make the situation worse.

Choose  acetone-free nail polish remover  and  avoid artificial nails or gel nails  if you notice your nails are getting weaker.

5.  Protect your hands

Wear gloves when doing housework or gardening. Regular exposure to chemicals and moisture can dry out your nails and the surrounding skin.

It’s normal for our bodies to change as we age—and our nails are no exception. Vertical ridges on your fingernails are incredibly common and, in most cases, simply a sign of aging. However, your nails can sometimes offer subtle clues about what’s happening beneath your skin.

By paying close attention to how your nails look and feel, and giving them the care they need, you can keep them strong, smooth and healthy for years to come.

If something doesn’t feel right or changes quickly, don’t hesitate to discuss it with your healthcare provider. When it comes to health, even small details can be worth examining.
