The Bottom Line
Vertical lines on your nails are usually nothing to worry about — they’re often just a normal part of aging. But your nails can act like tiny health diaries, reflecting changes in your body’s balance and nutrition. Paying attention to their appearance can help you catch small issues before they become big ones.
So next time you glance down at those subtle ridges, see them as what they are: quiet storytellers of your body’s inner health.
