I'm now worried that my nails will fall off. 4 feel like they are going to fall off and it hurts constantly. It's going to take months to repair my nails. I would never recommend this.

I bought about a month ago, it seemed like it was working and hardening my nails but now they’re lifting. Same as everyone else says. Really not worth it

Think it’s made a slight improvement but nothing massive tbh it’s a lot of money for the benefit. Think others are better than this

Unfortunately, this product has made a bad situation worse. I purchased to repair damage from a round of acrylics after a round of dip. Since using, mail nails have split down the center or peel and tear. My nail beds hurt from the damage. So sad that an OPI product has done this. I have been an OPI customer for years.
Unbeatable

Consistent application 2x a day has proved beneficial in less than a week. I also have a smashed fingernail regrowing and in combination with a growth treatment polish, this has made my nails so durable, I’ve been able to grow them to a length o haven’t been able to achieve before due to flaking, chipping and breaking near the hyponychium.
Horrible product & not worth the price.

Bought this after doing gel polish for a while in hopes that it would fix my nails better than Nail Envy, and to my surprise right after using it for 6 days, twice a day as instructed, my nails started LIFTING FROM THE NAILBEDS! I’ve never had this happen to me even from low grade, cheap nail polishes. This product is awful especially for the hefty price point and clearly I’m not the only one who thinks so. Don’t waste your money.

I bought this product in the first week of Jan 2025 and used it for recommended days. Three months on and my nails now look horrible and are in an awful state. All my nails have lifted from the nail bed and are basically coming off. I have also experienced some pain and a tingling sensation. I would not recommend to buy as there is clearly a problem with the ingredients OPI have used. I have informed OPI about this and I’m now waiting for my nails to grow out which is going to take some time. I wish I never bought this product. I feel so insecure to show my hands and try to keep them hidden away so people do not see them. I will not be using the nail envy strengthener too due to ingredients used.

Used this 2 years ago but had to stop as my nails started lifting - thought I had a fungal infection. Tried again end of last year on weak healthy nails and the same thing. My nails lifted and were dreadful. I thought the fungus was back. Now I realise that the lifting was caused by this product. I can’t recommend it. There’s something very wrong with it.

Like many others, I have developed onycholysis after using this product: my nail plate started separating from my nail bed. I had high hopes, but I can not recommend this product at all.

I started using this product in January 2025 and at first it worked great. By the first week of February my nails are now lifting from the nailbed and very thin. Do not use this product.
This REALLY works!

I have the weakest, flakiest nails possible, had to stop using acrylics as I had a stubborn nail infection on two nails, so grew them out, started using this very expensive product and yes! Literally 6 weeks later I have a natural nail growth! I really didn’t believe it was possible to achieve healthy nails after decades of abuse BUT I’m a convert. Yes it’s expensive but yes it works. Go for it! My age is 61 if that helps! So…… never 2 late
Beware! Nail pulls away from nail bed after use

Please pull this product from your list and get to investigating what is going on! Users are having their nails detach from nail bed. This will cause infections and before you know it the best nail polish company in the market has been sued and is gone. Please don't let that happen OPI. Just pull this product and stick to making beautiful nail polishes instead of treatments.
