Review (5/5): This is as good as it gets
I have fingernails that split, flake, break, etc. I normally have to keep them cut to the quick.
This product goes on my nails and UNDER them as they grow out. I generally start with a double coat and then move on as they grow out. You have to apply s ome kind of polish (even if it is a simple clear coat) on a daily basis so they remain flexible. Starting from scratch, which is a pain in the rear, after the double coat startup and a layer of polish I will get 10 days to 2 weeks. After that I have to take them all the way back to the beginning and start over. I've tried everything, including super glue to the extreme and this is the only thing that works for me.
