If you do have a fungus, we recommend removing the artificial nail(s) completely, and applying Tammy Taylor 'Thymolize' 3-5 times a day, underneath the free-edge of the nail at the Hyponychium (skin attached to nail-plate), every day, until the natural nail reattaches to the nail-bed.

The "same" goes "for" toenails.

If you do not see any improvement within 7 days, consult a physician.
