Nail Defense Strengthening & Repairing Basecoat

This is a protein strengthener that can be worn on its own or under nail polish. It has a high gloss shine making it great to wear alone without polish when you grow and repair your nails for a week or so. However, its not my first choice as an actual base coat as it is very slow drying, at least a full 10 - 15 minutes to dry vs 1 - 2 minutes for my other base coats. Rushing it causes bubbles for …Read more

I've been polishing my nails nearly every week lately, and my nails were showing the effects! My nails felt dry and ridged when they had nothing on them, so I bought this strengthener to use under polish or when I don't feel like doing a colored manicure. It dries very quickly and leaves a nice shine.I applied a new coat of this everyday for a week, without adding any other polish on …Read more

My brush was uneven and I haven't seen growth though I have seen strength and hardness and it lasts long as a base and top.

I love this stuff!! it's my base and top coat. when I bought it, I had started painting my nails so frequently they were turning yellow and peeling from the stress and chemicals and this has helped a lot. I notice a lot less pealing, my nails have a better chance of growling longer. I always do two coats of this as a base, then however much color I want and then another coat of this on …Read more

Not bad. Does make my nails a little stronger as long as I keep applying. Doesn't do much to stop dryness or the splitting that comes from it. Not as good as OPI Nail Envy, but a decent cheaper substitute.

I've undertaken months of experimentation before concluding that this product actually lives up to its claims. My nails are terrible, thanks to genetics. They're weak and flexible, split and peel, and tear really easily. I've been doing manicures regularly for about a year, which has wreaked further havoc, and they were really stained from always being painted.

Packaging: The bottle is HUGE (6oz/18ml) and has a rubberized handle which seemed silly but I actually loved it. The brush is thin, but so is the product so it works perfectly. I paid $8 at a CVS.

Product: This goes on thin,smoothly, evens out my nail texture, and dries quickly. It also dries with an amazing shine so it could easily be worn on its own. I generally put a base coat, two …Read more

I use this as my base coat as darker nail colors are my mainstay - OPI Russian Navy & OPI Marooned on the Subway for example - and this keeps them from discoloring my nails. The strengthening is a bonus as my nails are pretty strong to begin with.
