Vertical ridges on fingernails are common, especially as people age. These lines run “from the base of the nail toward the tip” and often become more visible over time. This change is usually “a natural part of the aging process” and not a cause for concern. As the body ages, nail growth can shift slightly, creating a textured appearance.

Daily habits and environment can also affect nails. Frequent handwashing, using cleaning products without gloves, or exposure to dry indoor air can make nails drier and more ridged. Nutrition matters too. Lacking nutrients like “biotin, iron, or zinc” may subtly affect nail texture, often alongside other signs like dry skin or brittle hair. Improving diet and hydration usually helps.

Most vertical ridges develop slowly and are harmless. However, sudden or severe changes in nail “shape, color, or thickness” may signal issues with circulation, skin health, or hormones. While rare, it’s smart to see a healthcare provider if changes are persistent, sudden, or accompanied by pain, swelling, or unusual discoloration.

Supporting nail health is simple. Regular moisturizing keeps nails flexible, and a balanced diet with vitamins and minerals promotes growth. Protecting hands with gloves and avoiding harsh nail treatments like excessive buffing or trimming also helps maintain healthy nails.

While vertical ridges are often normal, “mindful habits can keep your nails looking healthy and feeling their best at any stage of life.” Simple care, hydration, and nutrition can make a noticeable difference.
