Wavy nails, characterized by ridges or grooves, can appear either vertically, running from the cuticle to the tip, or horizontally across the nail. While vertical ridges are often harmless and can be a normal part of aging, horizontal ridges (known as Beau’s lines) can indicate disruptions in nail growth and may warrant further investigation.
2. Aging and Hormonal Shifts: Why Nail Texture Changes Later in Life
As we age, changes in hormone levels and overall cellular function can impact nail growth. The production of keratin may slow down, and the nail matrix may become less efficient, leading to thinner, more brittle nails or the development of vertical ridges. Hormonal changes, such as those experienced during menopause, can further exacerbate these effects.
In addition to hormonal shifts, reduced circulation and nutrient absorption in older adults can contribute to nail changes. Ensuring adequate nutrition and maintaining good circulation can help mitigate some of these age-related changes.
