I am in my 3rd month, I do know it takes about 6 months to see results.  I do find it is helping my nails--they are stronger and look so much nicer.  I am hoping it will strengthen my fragile hair.  I have never had patience to continue with treatments before--I want to see instant results--but I now realize that in order to see any improvement it will take time so I am committed to giving this treatment a chance.
