Hi,
As it takes 6 months for the fingernail to grow from base to tip and 12 months for the toenail to do likewise, it will take 6 months for loceryl to work for fingernails and 12 months for toenails.
Early clinical improvement (the base of the affected nail will begin to look normal again) may be seen after 3 months but loceryl application must be continued for the entire period to complete the treatment.
Hope this helps!
