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.

Beau's lines: Beau's lines, which are grooves that run horizontally across the nail plate. They usually develop when nail plate growth, which begins in the nail matrix (located under the cuticle), is temporarily disrupted. This can occur with direct injury to the nail matrix; an inflammatory condition such as psoriasis; infection around the nail plate; repetitive picking at the nails or cuticles; or sickness.
