No worries: Vertical nail ridges extend from the cuticle to the tip of the nail. Vertical nail ridges often become more numerous or prominent with age, possibly due to variations in cell turnover within the nail.
If your fingernails change color or you develop horizontal nail ridges, consult your doctor. These changes could indicate an underlying health condition.

Mees lines: They are an old indication of arsenic poisoning, but in fact, it can be an indication of any recent illness. They are benign.

Maybe minor injuries: They are benign. Usually no cause is identified. No harm. They are tax-free. Ignore them.
