I absolutely love using this on my nails. I've always had brittle nails and never could I find a pill or supplement that would help make them stronger. This is longest I've gotten my nails! Very good product.
I have been using this product and my nails are still breaking at the ends. It does make your nails look nice and shiny, but when I type and do my day to day tasks, the polish/strengther chips, thus my nails are still breaking on the ends and I've had to keep them trimmed short. :(

I have always done my own nails. And, I always start with OPI nail strengthener. Even in Michigan winters, freezing outside and dried out warm inside, keeps my nails strong and maintains the length. I'd give this more stars if I could.

Let dry really well between coats and it will really strengthen

I use the natural nail strengther and it does prevent my long nails from bending or breaking. I thought it was the same as opi base coat but it does respond differently on my nails.

My nails are stronger. They don't break or split because of the ridges.

Before using this product my nails were splitting and breaking and had very little growth. With use, my nails are no longer splitting and are growing nicely.

Since Feb I've only been using nail hardener on my nails because they were so weak & dry-no nail polish, no top coat. I noticed the salons use OPI natural nail strengthener so I went to Ulta & bought my own bottle. It's so easy to use & dries very quickly & a very good value for the price!

Started peeling same day that I applied it. By two days later it was completely off. Don't waste your time or money.

Some comments have been made about the wear of this. I wore it for a week and for me it stayed on pretty well, but I do suggest you build it up. A layer every so often keeps if looking nice. I go for the natural nail look so. I also have dry weak nails and this has so far made a difference. I want to try Nail Envy tough to compare results.

Just took my gel nails off for a breather. Hoping that my natural nails will strengthen up. So far this is working really well.
Robin from Charleston, SC
It just doesn't work. Peels off and is certainly not worth the effort or money. Very disappointed in this product.

I bought this for my mom to use since her nails are fragile. I like the product, so when she commented on my nice manicure, I thought this would help her to improve her nails.

I like pretty purple on my toes, trying to bring back my fingernails from abusive gels! I love OPI

I can never get my natural nails to grow, so in beteeen manicures I'll supplement with a nail strengthener. I've given this multiple efforts but the next day half of it has come off my nail. I don't do manual labor or work in a kitchen, so it's not like my job should affect this. It's normal wear. I swear I will do so good with the application and the next morning all the tips of my nails are bare. Sally Hansen has the best nail strengthener hands down. I'm using this stuff up and then switching back to my old stuff.

I love the way it dry's quickly and smoothly.

After two days of applying it, it starts peeling. It's useless.

I heard about this product from a friend while visiting in Canada. I swore her nails were professionally done in gel treatment!
