How soon will I be able to see improvement to my toenails or fingernails after treatment?

It usually depends on the origin of the fungal infection.  If it was at the “root” of the nail, improvement can be seen as early as 3 weeks. A continuous improvement will be gradual as the nail continue to grow out. Typically, a significant overall improvement will be seen after 3 months. As a rough estimate, toenails may take 9 – 12 months to grow out completely, and fingernails may take 6 – 9 months.
