Causes of Fingernail Ridges, Pitting and Curved Nails. Normal Lines and Ridges on the Nails. Longitudinal ridges (running from the cuticle to the free edge of the nail) may be due to aging and not a sign of any disease. Nail beading, where the nail loses its smooth curvature, is also a normal part of aging.
You wrote about weak, brittle fingernails with longitudinal ridges. I have strong nails with horizontal ridges. What causes this, and what can I do about it? A. You may be referring to 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 even a manicure.
