What is the main cause of leukonychia?

The most common cause of leukonychia is injury to the nail bed. These injuries can occur if you pinch or strike your nail or finger. Frequent manicures and pedicures or the use of gel or acrylic nails can also damage nail beds. Several other causes may be responsible for the unusual spots on the nails.

Is there a cure for leukonychia?

There is no universally successful treatment for the whitening of the nails in people with leukonychia totalis. However, if the condition is known to have an underlying cause, treating that cause (when possible) may improve the condition.
