OPI Nail Envy Advanced Strength Nail Strengthener - 0.5 fl oz

Love this my nails are brittle and split I used this regular for a few weeks and I now have a bit of growth for the first time in a long time not cheap but worth it

This is a must have in the vanity! It really has helped strengthen my nails, goes on clear so can be used under a nail Polish! Fantastic product and would Definitely recommend.

This product works incredibly well to nourish & grow my nails.

WHY DID YOU RUIN THE ORIGINAL FORMULA. I HATE THIS VERSION. MY NAILS ARE PEELING WORSE THAN EVER. I’M SEARCHING FOR OTHER PRODUCTS. I’M F ITS THE FORMADEHYDE, JUST DONT SELL IN THE MARKETS THAT BAN IT. I AM SO SAD AND ANGRY.

I've used loads of different nail hardeners over the years but always come back to this. It just works. It's quite expensive but does last for a long time.

Have to fully agree with all the other 1 star reviews - the new formula DOES NOT WORK. I used to get so many complements on my nails - long, strong, and everyone thought I'd had them professionally done. I told them I had a system - 2 coats Opi original nail envy (green writing), 2 coats any Opi color and 1-2 coats Opi RapidDry. They looked like acrylic and lasted at least a full week. Now my nails are short, cracked, peeling and even if I do use my "system", I'm lucky to get 3 days out of it. Please, please go back to the original!!

Easy to apply , great that it is clear so I can put it under other nail colours. Really made my nails stronger. Continued to use even when I’m not wearing any other nail varnish

The OPI strengthens the nails perfectly and they don’t crack or chip. I am so happy with it, definitely recommend it to my friends and they are obsessed with it too. Definitely worth all your pennies.

This new formula of Nail Envy nail strengthener is horrible. Nothing like the first original formula I will not be using this again. It has destroyed my nails. The last time I use this product was 2019 and my nails were gorgeous that product strengthen my nails. They grew so long and beautiful. That was the product with the blue writing on it. This one the new formula with the black writing on the bottle… Don’t waste your time! Don’t waste your money! Don’t destroy your nails!!! if I could give it 0 stars I would, but I have to put one star in order To submit a review

I used the original formula Nail Envy for years and it was a fabulous product. My nails grew strong, long and beautiful. I wasn't aware that the formula had changed and purchased 2 bottles. The new formula is useless. My nails chipped and broke as if I hadn't used anything. I threw both bottles out and went on a quest to find the original formula. I purchased 5 bottles of original that I found online which should hopefully last me a couple of years. I don't recommend the new formula at all. Waste of money.

I’ve been using OPI Nail Envy for a few weeks now, and I’m really impressed with the results! This product promises to strengthen and protect fragile nails, and I can confidently say it works. The formula is easy to apply, dries quickly, and leaves a nice glossy finish. My nails feel much stronger and more resilient, and when I paint them, the polish goes on smoothly and evenly. What I love most is that my nails no longer feel weak or peel like they used to. Plus, the product has a mild scent and doesn’t irritate my skin, which is a bonus. I highly recommend OPI Nail Envy to anyone with weak or easily breaking nails. It’s an effective and easy-to-use treatment, and you’ll see visible results in no time!

Everyone has said this but I tried it for myself. Can confirm, the new formula is terrible. So sick of companies not listening to their consumers and changing their classics. PLEASE don’t waste your money, try another brand’s nail strengthener instead.

Terrible that they would change the formula that worked wonders to this. It peels and causes my nails to become brittle. OPI should listen to it's loyal customer base before it loses more business. Will not be coming back to any of their polishes until the old formula resurfaces. Corporate greed at its finest.

The new formula literally makes my nails peel and split. I notice they are weaker after using this product. So sad because the old formula would allow my nails to grow out up to 1 1/2 inches. Not anymore. Please bring back max strength formula with green writing! I beg

New formula REALLY dries out my nails. Nail Envy used to be the miracle elixir that saved my poor thin nails, but now it makes them worse! Had to stop using it. Looking for new nail strengthener. So sad...and frustrating.

I used this product for years & it worked so well but they have changed the ingredients and it is terrible. Causes your nails to crumble & break. No one should buy it.

I used the old formula for 4 years and my nails were brilliant. I ordered another bottle, not knowing the formula had changed and wondered what was going off!! The polish chipped, wore off within days and my nails beneath were weak, soft, flakey and spilt!! A nightmare.....!!! Wasted my money and absolutely gutted!!!!

Very good product, good value.

I don’t know what happened but this formula changed. My nails peel and chip after use. The opposite of what this product used to do for me.

Recently bought this classic strengthener. So disappointed. Nothing like the previous product which I had used for years and was amazing. I have concerns that this product actually makes my nails flake rather than helping them. I won’t be buying again
