OPI Natural Nail Strengthener, Vegan Formula, Infused with Vitamin A & E, Helps Prevent Discoloration, Strengthens Nails, Clear, 0.5 fl oz

I have weak nails. My toenails can split fairly easily and my fingernails easily chip. I’ve been using a couple other products for the past 15+ years. This is my first time trying OPI Nail Strengthener. It works. Definitely as well as the other products I’ve used…and possibly a little better. I’ve been using it for only a week, however I’ve noticed that my nails seem a bit stronger with OPI compared to the other products. I like OPI well-enough that this will become my go-to over the other products.

Liked it

my nails have always been soft and this is my first time trying to nail strengthen but i can physically feel the difference from before and after in just one coat. it’s now so tightly and i can actually tap it against hard wood and it makes a sound just like acrylics it’s insane. amazing, i love it. it always helps with my bad habit of biting my nails and it’s so hard i cant even bite it. AWESOME 10/10 stars

I do not know how people go seven days without having to remove this, honestly. I can use it for 3 or 4 days max before it starts peeling off by itself &, sadly, taking my very fragile nails with it. So, I've taken to using it for 2 days, taking it off, and starting over. I might be able to stretch it to a third if I don't see any thin spots, but generally by the fourth day it's peeling. Is it helping my nails? It's hard to tell because as I said, it has contributed to some of the peeling. But now that I am removing it more regularly, I hope that it will. I think doing the same thing with any regular clear polish or base coat would have the same effect though, so do with that what you will. I do think I had better luck with a different brand and as soon as I can find that one again I plan to go back to it.

I only wear clear nail polish, and this one goes on easily with a soft lustrous shine and lasts for well over a week. It wears off gradually, so there's no point at which I feel like I need to rush to remove it and reapply it.

So far, it is helping my nails not to split. I take vitamins too, but my nails starting splitting as I got old. This seems to be very strong barrier . . .will wait until the long-run to see if it works as well when they grow out. I think it's very promising!

i give it 3 stars because i have tried very one u could find this was one that was recommended lot and it still would peel off my nail i’m not sure why any tips please help i want to grow my nails but they brake so easily

I was having a problem w my nails breaking as soon as they grew beyond the nailbed, which is so unlike me. They also had a terrible dip in the center on top, again not normal for me. As soon as I began using OPI Nail Strengthener, my nails grew steady and strong and I finally cut them down!
