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.

Many reasons: Vertical ridges on nails are basically harmless & can be related to heredity, aging, & nail dryness or injury. The appearance of ridges may be reduced by regular moisturizing of the nail & cuticle & avoidance of harsh soaps that are drying. Nail appearance can reflect overall health and nutrient status so supplementation may help. Consider fish oil, biotin, &/or a multivitamin with minerals.

Can be a lot: Fingernail disorders can be wide and varied as far as causes. Dermatologists are experts in fingernail diseases. White markings, called leukonychia, can be caused by trauma, infections, drugs, or other systemic diseases.

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.
