It does what it says it will do. You just have to be dilgent and follow the directions. My nails are stronger and not brittle anymore. The price is great also.

COMPLETELY SATISFIED

I've always had soft, thin and weak nails that break very easily, actually tear. This formula is outstanding. Nothing against nail salons, but I no longer have to go for active length, hard beautiful nails.

Results speak for themselves

I didn't think this would work. I was honestly grasping at straws having tried everything else for my dry, peeling, thin, brittle nails. After 3 days of using this I noticed no more breakage, no more splits or damage. I just reapply every couple of days or remove with a gentle formula remover and then reapply if there are several layers built up. I'm telling everyone about it.
