Be patient.: Remember that one very important part of the treatment of your nails is to stop the spread of the fungus to other nails and the rest of the skin. The cosmetic appearance takes a long time to change and it depends on many circumstances such as your health, prior health of the nail, the season. Toenails grow slower. If all involved, it will take 12 to 18 months for a new nail growth to appear.
