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.

Works great! I used to get acrylics but decided to take a break and have been growing out my natural nails and until using this strengthener they would break once they'd getting to a certain length. The instructions call for 2 coats but I usually use 5-6 and it's been amazing!

Good product but for some reason on my nails it peels off pretty easily.

It’s ok. I liked the old formula better. Felt like it was stronger and stayed on better, but this is an ok alternative.

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 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.

I've had weak flimsy nails for so long and my nails grow pretty fast and pretty long so long plus weak leads to really bad deep broken nails that would break into the nailbed. it started happening so often to numerous nails and i was so sick of it and it was painful and i was also tired of wrapping bandaids around my nail to protect it from breaking any further. I bought this to help strengthen my nails and it works like a charm! my nails feel so much stronger and I feel like I can grow out my nails and not worry that they will break again.

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
