This fixed my brittle weak nails , i couldn't believe what it did to my nails made them like new healthy and i can actually grow them out now! But do not keep sing this bottle after you finish the bottle if you keep using more bottles it will make your nails weaker. So just one bottle is enough for the time. Amazing product that actually works!!

I was wearing gel nails for about three years but than I had to switch back to my natural ones. As you could imagine my nails weren't healthiest, however my manicurist recommended me this treatment. For about two months, I lacquered my nails every day with this polish. It took some time to old damaged nail to grow away, but now I have very strong nail (almost comparable to the gel one).
Now I'm using it as a base coat and I'm very happy with it.

Nail Envy has improved my nails significantly. My nails would bend easily, break and peel. After I began using Nail Envy they strengthened with a week. I use it as a base coat, over nail polish to help it last longer, and on it's own.

I've been a nail biter my entire life, with the exception of stopping 8 weeks ago. To help me along, my nail tech recommended this and I've been so pleased! It has helped me to grow strong and sturdy nails, no doubt about it. While I was using Butter London basecoat, I switched to this and found my nails were a bit stronger...which is the point! I will still use my BL base to wear as a shade, or maybe to mix it up, but Nail Envy seems to be fantastic. My nails have grown so well, I can't believe it!! No yellowing, no problems, only good things to say.

I have used this product and have always been happy with it. It literally makes my nails so hard they can "chip" if i hit them on a table hard enough! Yellowing? No. You are supposed to remove it once a week and start over. I think it's a great product, plus they sell a clear matte for men!

Works great, made my nails look nice, and kept them strong.

I absolutely love this stuff! My nails always snag and break along with some peeling. Sally Hansen works but not as quickly. I love the glossy look. I only find one drawback and that is that it doesn't always go on smoothly...you can see brush marks. The fact that I haven't had any breaks or peels makes up for it. I haven't seen growth but it has only been a week. I also have been applying a coat a day as opposed to the directions of every other day. I keep obsessively staring at my nails. I will definitely repurchase!

This is not a good product. It's expensive. It turned my nails yellow and made them soft and start peeling. It does not work at all. Not sure what difference it made to the others for it to get such good reviews, but I would certainly never buy it again.


The OPI base coat polish, however, works great as a nail strengthener. It doesn't yellow your nails, and it protects them nicely either with color or without.


Don't waste your money on the OPI Nail Envy and purchase the OPI Base Coat instead.

I bought this product becuase of all the rave reviews all over the net. I hadn't really worn polish for years and a few months ago started having polish constantly on my nails. My nails were a little weak before, but did them in and they started peeling, breaking easily, being thin and bendy. I bought this even though it was expensive ($17!) and followed the instructions for 3 weeks. The first two weeks I thought maybe it was just taking it longer to do it's thing and I needed to give my nails time to grow out past the peeling parts. However on this third week I've realized my nails have grown far past those points and there is a LOT more new splitting and peeling going on than when I started!

I will admit the formula does keep the splits together and a little less fragile while it's on, but as soon as you get your hand wet and your nails bend it comes right off. How can this product hope to help with peeling and split nails when it can't stay on them? The past few days I would touch up my ends in an attempt to keep them from breaking off on the "off" days and all it did was turn those tips yellow and make them peel even worse!

Sorely disappointing for a product that costs so much!! $17 down and only splitting, breaking, peeling, yellow nails and 3 weeks of my time gone to show for it. Guess I'll have to keep looking for a nail repair/strengthening product that actually works!

My nails have always peeled, chipped, and broken easily my entire life and have never found a product that works for me. Until now. I've been using the "Sensitive & Peeling" version of Nail Envy and it is fantastic!! I have to use two coats, but it dries very fast so that's not a problem at all. Alone it makes my nails shiny and pretty. Sometimes I use it under a color and it works just as well. My nails are finally growing for the first time in my life. I just can't say enough good things about this product! continued >>
