I used the OPI Repair Mode as directed for six days, applying it 2x a day.
I have since been using two coats of the OPI Repair Mode with two coats of the new formula of Nail Envy. Then on the third day I apply the Nail Envy again.
My nails actually did not break, split, or peel.
However, I also started using a crystal nail file, Mont Bleu. There's a difference in glass nail files that I've purchased from Target or CVS with the Mont Bleu files.
I'm not really sure which of the three products is working, but my natural nails have never looked better. Most products don't work as claimed. However, these three products actually do work.
I'm also using a simple rubber-tip cuticle pusher.
I think I was just too rough on my cuticles, and that contributed to my weaker nails.
Just wanted to pass that along, in case you're looking for any new products to try.
