    remover. Keep the bottle tightly closed.

  4. e) Repeat the process above for each affected nail.
  5. f) Treatment should be continued without interruption until the nail is regenerated and the affected areas are finally cured.

The required duration of treatment is usually six months for the finger nails and nine months for the toe nails (depending essentially on the intensity, the localisation of the infection and the infected area of nail).
