Re: Ridges on Fingernails
The nail plate 'rides' forward on the nail bed over a 'rail and groove' effect - much like a train rides forward on its' tracks. As we age (or sometimes due to a recent illness or other health issue), these 'rails' and 'grooves' become apparent on the nail plate as vertical ridges.
As we age, the 'tidal flow' of moisture from the nail bed that bathes the nail plate diminishes. Since the nail plate cells are no longer as 'plump' as in our youth (or better health), vertical ridging results. Mine began on my right thumbnail -- I can now see the effects on my left thumbnail as well. I keep them from getting worse by applying a good quality nail and cuticle oil at least twice daily. I recommend an oil that contains jojoba and vitamin E oils. The jojoba has a very tiny molecule that can penetrate the surface layer of the skin and between the nail plate cells and will draw the vitamin E in after it.
