The Bottom Line
Nail ridges are a common and usually harmless feature of natural nail growth. Vertical ridges often develop as part of the aging process, while horizontal ridges may sometimes reflect temporary stress or illness.
Your nails can act like a small window into your overall health. Paying attention to changes in their shape, texture, or color can sometimes provide useful clues about your body’s well-being.
If you’re ever unsure about changes in your nails, a healthcare professional can help determine whether they are simply cosmetic—or something worth investigating further.
