How nails become white?

The natural colour of nails is pink, but sometimes, white lines or dots develop on one or more nails. This condition is known as “leukonychia”, but it’s not harmful. Many healthy people also have these spots on the nails at some point in their lives. So, if you have these spots, it doesn’t mean you have a serious disease. The white lines appear due to fungal infection, nail injury, allergic reaction, and mineral deficiency.
