Hidden Clues Your Fingernails Reveal About Your Health

4.Rippled or Pitted Nails

Loss of smoothness, tiny pits, or ripples can reflect deficits in zinc, calcium, or vitamin A, or emerging skin disorders such as psoriasis or eczema. Psoriasis commonly produces pitting, and nail severity often mirrors skin activity. Alopecia areata and lichen planus can also mark nails. Care focuses on the root condition; gentle grooming helps limit added damage.
