Causes of Fingernail Ridges, Pitting and Curved Nails. 1  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.
Downward curved nail ends may denote heart, liver or respiratory problems. White lines show possible heart disease, high fever or arsenic poisoning. Ridges running up and down the nails indicate a tendency to develop arthritis. Nails that resemble hammered brass indicate a tendency toward partial or total hair loss.
