OPI Nail Envy, Nail Strengthener Treatment, Original Formula, 15 ml

This stuff is amazing, I've been using it for 3 weeks and im so impressed. It's quite glossy for the first few days then starts to dull and shows a slight yellow tinge making it look quite natural. The strength in my nails improved massively within 4 days. Quick and easy to use, apply 2 coats day 1, apply 1 further coat on day 3 and again on day 5, remove and re-do day 7. The instructions advise to use it for 8 weeks if for treatment only purposes.I have been using Blue Cross cuticle remover once a week and CND solar cuticle oil 3-4 times a day. Once my nails are at a good length i will continue to use this as a base coat with whichever coloured polish i use. This is worth every penny!

Wouldn't buy anything else. It's not cheap but it works, so good value. Good durability and a clear colour, although repeated use causes nails to yellow

I basically destroyed my nails after using my own gel nail kit a bit too much and after seeing the reviews for this, I gave it a go. It’s so good, you do need to have patience because obviously the nails won’t grow instantly but ordinarily my nails are really weak and bend easily but with this they have grown really strong, they feel as strong as they do when I’ve had several coats of gel on which is amazing. I’ve seen they do strengtheners in different colours too which I’ll be trying next because I do miss having colour on my nails. I used a cuticle oil regularly with this as well which probably helped. It’s a little pricey but I do think you get what you pay for so it’s definitely a worthy splurge

I have used the Original for at least 10+ years as my nails are very thin without it. But after using this product they are healthy and strong. However I have just bought a new bottle and it no longer says Original on the bottle. It doesn't seem as good and peels off after a couple of coats and doesn't seem to be as thick as it was. I will have to wait and see if the new formula is as good as the old Original one.

Usually I enjoy finding dupes/cheaper alternatives but honestly it's better to buy this product. Worth every penny! My nails were completely damaged and thin - I was inexperienced in removing gel nails, ended up stripping most of my nails down. Used this product and a month later my nails were in their best shape, strong and healthy!Now I use this product inbetween my manicures to give my nails some support if my nails are longer so they don't chip on the sides.

I’m on my second bottle of this, as it’s the only product that stops my nails breaking and allows me to have longer natural nails. It stops breakage and peeling. It’s easy to apply and dries quickly.

Really does strengthen nails

I've suffered from soft nail through out my years. So, i resorted to having my nails done at a nail salon for the last 20 years. Throughout the Covid period i suffered greatly and plasters where my nails best friends because of the constantly breakage. Thank God I was working from home! What an unprofessional looks it was. Started attending the nail salon again and because I have High beds underneath my nail, and I'm afraid that one day I will be cut, the fear was agonising. Anyway, I had to had an operation so i had to romove the nails, so I asked my technician if she could recommend a product that would give my nails some strength until i heal and can get back to the salon. She recommended this.This product is very good! My superlative description may not be strong enough to really express how great this product is, but it is an absolute pleasure using it.Thanks, O.P.I
