As we grow older, our bodies naturally go through changes—and our nails are no exception. My aunt, like many others, began to notice her nails becoming more brittle and prone to splitting over time.

While there are plenty of nail hardeners on the market, they can be costly and full of harsh chemicals. Thankfully, there are affordable and natural remedies that can help support healthy, resilient nails without the extra expense.

Nail splitting, or onychoschizia, happens when the layers of the nail separate or peel away. It’s often caused by repeated exposure to water, chemicals, or physical damage. But underlying health issues and nutrient deficiencies can also play a role. Understanding what’s behind weak nails is the first step toward finding a solution.

How Aging Affects Nail Health

Aging naturally leads to drier nails due to decreased oil production. Circulation can also slow down, reducing the nutrients delivered to your nails and causing them to grow more slowly and become more fragile. Recognizing these changes makes it easier to take proactive steps to care for your nails.

Support from Within: Diet and Hydration

What you eat plays a major role in nail health. Foods rich in biotin—like eggs, nuts, and seeds—can help strengthen nails. Protein, iron, zinc, and omega-3 fatty acids also support growth and resilience.

In addition, staying hydrated is key. Dry nails break more easily, so drinking water throughout the day and using moisturizing hand creams can help keep nails supple and healthy.

1. The Power of Natural Oils

Certain oils, like coconut, olive, and jojoba oil, are packed with nutrients that nourish both the nail and cuticle. Gently massaging these oils into the nail bed on a regular basis can improve strength, reduce breakage, and keep the nails moisturized.
