Why do people have white spots on their nails ?

We often see white spots on our finger nails . This is a very common issue and entirely harmless .

The exact cause for these white spots is not known . Most common cause is injury to the nail bed . These injuries can occur when we pinch or strike our nail or finger .

Mineral deficiency is the one more cause . Zinc deficiency and calcium deficiency are most commonly linked to this  issue .

These white spots , most of them , will disappear on their own without treatment . We must protect our nails as best as we can . Also we must eat a balanced diet and maintain adequate levels of vitamins to prevent white spots on nails .
