I use this pretty regularly and it has warked on my toe nails but not as much on my fingers. It may be bacause my hand are under soap and water or moisturizers but i still really like it for my pedicure bag.
I just discovered this product 5 days ago and have been using it three times a day. I have really damaged, brittle, and thin nails, with dry cuticles. I am amazed at the transformation in such a short period of time. My nails look shiny and healthy, and my cuticles feel moisturized. I highly recommend this stuff!
