I just removed my nail polish yesterday and put this treatment on my own nails (have not had a chance to paint them yet but that will change...very soon! LOL). I can't believe how much stronger my nails feel after having had it on for less than 24 hours. I only applied 1 coat because I was planning to use it as a base coat but if you are using it as just a nail treatment you are supposed to apply 2 coats to bare, clean, dry nails and repeat every four days for four weeks. I'm just using it as a base coat as my nails are not that bad but the tips are a little soft/weak from when I had my gel nails and where some of the gel pealed off it probably took a small layer or two of my natural nails with it. But I tell you, this stuff is like a little nail miracle in a bottle.
I have to be honest, I can't compare it to really any other nail treatment as I have not used anything like OPI's Nail Envy or anything like. I was using Sephora by OPI's Strengthener and I didn't notice a difference. It just seemed like a basic base coat to me.
If you ever try this nail treatment I would love to hear from you. Please leave a comment on this post and let me know what you think/thought.
