The product is perfect! It made my nails hard and they don't break! It also dries immediately and doesn't leave any strange feeling! It doesn't sting either. It cools slightly upon application and then you don't even realize you put it on! It lasts forever! And because it's a treatment and you do it for 7 days and then stop, it definitely lasts for months!! It's definitely worth the money!

Truly miraculous. It saved me. It's the only thing that made a difference to my nails and really from the first week of application it had results. I highly recommend it.

There is no better treatment for weak nails. Before, my nails were extremely thin and brittle, after years of using gel. Now they are strong and resilient, so much so that with just regular polish they give the impression of gel/acrylic. Just be careful not to let it come into contact with cuticles because it will work on those too!

after trying everything else, I had almost given up! my nails were thin and breaking. this product is the only thing that helped. it soaks into the nail within seconds.. it's not a coat on top of the nail.

Due to years of using semi-permanent nail polish, my nails started to lift from my fingers. The white part of the nails began to grow towards the nail. It absorbs immediately. It doesn't shine at all. I can say that with proper use they were saved. Only positives.

Very good! I saw a difference immediately in my nails! If you do it meticulously with the instructions it says, the nails are completely different in a week! No other treatment had helped me until now!

I'm not sure if it works miracles.

It dries quickly, nails do look harder and after just one use, however, I noticed that they became very dry and started peeling.

The best thing I have ever used. Even better than nail envy. It's like it fixes from the inside out. It's not a strengthening product but a repair one. I used it on very damaged nails (to the point of pain...) from continuous removal of artificial nails and it literally rebuilt them. On a friend who only had a few dents on the surface (from a wheel), it smoothed them out. I highly recommend it.

After first struggling for a month with an unrelated product that the technician who does my semi-permanent recommended to me, which did nothing (my nails were in bad condition from the removal wheel), I bought this and after 2 days of use, my nails are very different! Wonderful.

The product did not deliver on its promises for me. My nails did not harden and it did not prevent them from breaking or bending when I do chores. I wasted my money on useless carpets again

Excellent product!
After continuous applications of acrylic manicure, my nails had become very weak! From the second day, I saw a big difference! They hardened and grew longer without breaking!! I highly recommend it

Amazing product! Use it alone according to the instructions for 6 days and if your nails are in a desperate condition, like mine were, continue for as long as needed, with two coats and after 10 minutes, one coat of OPI nail envy original. Then, one coat of OPI nail envy original day by day for 6 days. On the seventh day, remove the nail polish, and start again until the problem completely disappears and you have fantastic nails. I have never used a more perfect product!
