vertical nail ridges

1. Introduction Deep vertical ridges on the fingernails are primarily a natural consequence of the aging process, reflecting a gradual decline in cellular turnover and compromised peripheral blood circulation to the nail matrix. As the production of keratin becomes less uniform over time, the resulting nail plate grows with longitudinal striations that become more pronounced … Read more

As individuals grow older, cellular turnover slows down, and the microvascular blood supply to the nail bed diminishes, resulting in uneven … Read more
