Had it sent to my youngest daughter and she said she could really tell a difference in her nails.they were not as thin and breaking so badly. She has RA which tends to badly effect the nails

Bought this for my nails to help them from chipping. I dont see wonderful results but I think its working. I should have taken a before and after picture.

I have to wash my hands a lot and this has helped save my nails! Along with taking vitamins. Much less breaking and cracking since I started wearing it. You need to reapply every few days and build up a barrier.

Update: I'm now a little more than halfway through the bottle and it has gotten so thick that it's impossible to brush it on smoothly, no matter what I do. It's just... Gloopy. Plus, I've been really struggling to pick up enough of it on the brush because the brush only reaches halfway down the bottle even with the lid completely screwed on. I remember seeing another reviewer mention this but I thought to myself at the time that I would never get that far into the bottle, but here I am a few months later, probably because it goes on so dang thick! Unsurprisingly, this gloopiness certainly does not help with the extra slow drying time.I now have an alternate option on the way and it can't get here soon enough!Original review: every time I apply this stuff it takes forever to dry and still remains tacky for an hour or more afterwards. I've made sure to keep the coats as thin as possible but that doesn't seem to matter. It's especially difficult to apply 2 coats as instructed when starting with bare nails because I have to wait so long in between them. However, some people say that this polish dries really quickly for them, so I'm wondering if not all of the batches of polish are the same.Beyond that, I do like how glossy this polish is and how wide the brush is. Since I use this by itself it does take a couple of coats before you can really tell that there's polish on my nails though.

Helped with my nail growth. I didnt see any progress after a week or two but eventually did, my nails started growing out and stopped being so brittle!

Compared to my wife's clear polish, this product seems to protect my splitting nails better. It has the right balance of hardness and flexibility to adhere and stay in position.
