OPINail Envy Nail Polish, Nail Strengthener Treatment with Biotin, Calcium & Vitamins for Strong Natural Nails, Vegan Nail Repair and Strength for Damaged Nails, Clear Nail Polish 15ml

I have used this for years after trying to find something which stops my nails breaking badly so far down they bleed.The nail looks beautiful when put in either on its own or over varnish.I put on every other day a light coat and remove all once a week. My nails are stronger and I feel I can show my hands.It’s so good I have bought for family members and friends who are now hooked.A great product at a great price and lasts a long time. I wouldn’t be without it

Tried this nail strengthener for about 3/4 weeks now. As my hands are constantly in water at the stables, my nails have suffered. They break easily, flake off and have been really bendy at the ends. Since trying Opi over this time, my nails are definitely improving, less bendy and flaky. I have still managed to break the ends of some nails, but overall they are getting stronger. I imagine that another few weeks I will have some good growth. I also use nail oil daily too. Definitely worth a try if your nails are struggling.

I have always been a nail biter. I do it when I’m bored I do it when I’m anxious and for 2025 I wanted to take more care of myself including my nails because it’s embarrassing when other people see them and how painful the skin around my nails get from picking and biting.This is my 1 month update of using this product. I try my best to apply once a day but life gets busy! But I mainly stopped biting my nails and keeping myself busy if that includes chewing gum or having a drink of water near me.Stopping the habit is hard to kick but it has definitely been one reason why I have seen some growth along side this product, nail oils and hand cream!Can I say this product works? Maybe? I like the smooth finish it gives and my nails do feel stronger. I am still a picker but having this top coat I tend to pick at that and not my actual nail then reapply.I would recommend but I would also look into your habits if you are like me :)

My nails love this stuff. I usually use it for about a week and then give them a break, and they always end up looking so much healthier. They feel stronger, look shinier, and just overall more put together. It’s probably my favorite nail product I’ve bought recently. It is a bit on the expensive side, but honestly I think it’s worth it—especially if you manage to catch it on sale.

Not really loving this. My nails have recently become very brittle and flakey. I wouldn't ordinarily buy OPI as it is not cruelty free, but I was feeling desperate and the reviews of this were great. However I have found it does not apply smoothly, the colour is chalky and it does not have a good finish. I was hoping for a something closer to a pink tint for daily wear, but the colour is far more obviously, which in itself wouldn't be too much of a problem except it doesn't look good! I have no idea if it works for strengthening nails as I have found, even following application instructions, it chips daily so needs to be removed and reapplied all the time. Which doesn't feel like it will be doing my nails any good either. I've now given up and brought a different brand's strengthener, in clear.

I was really excited to try this as my nails where snagging off after a gel Polish manicure.This polish made my nails brittle and weakened the surface as it would constantly peel off. Both finger and toe nails would snag at everything. Clothes, socks, cushion etc. Also the manicure doesn't last a day which means you're constantly reapplying every day and walking around with unkempt-looking nails.Today my fingers were hurting after i cleaned off the polish only for me to find I have white patches underneath my nails. So annoying to spend so much for a bottle of Polish only to have the opposite of the experience I desired.I'm going back to my cheap bottle of nail hardener is tested and trusted.Update.I'm suffering terrible onycholysis on both fingers and toenails from this! I find it believable, and almost impressive, that this damaged my toenails which have always grown thick and long. I should have paid attention to the negative reviews, this does not work for everyone. Or more accurately, this causes more damage for some people. Buy at your own risk.

My boyfriend has better nails than me. This can't happen haha. So instead of paying out a lot to get my nails done which my work also doesn't allow, I decided to try naturally improve them. Trouble is my nails always snap. But this stuff really helps! And they look tidy and shiny. I'm still working on them and reccomend the opi nail varnish remover as this will chip and coating over and make it bumpy. Better to remove all and start fresh, keep them tidy looking. And whoola. It's quick and easy. Applies nicely and it transparent. If I make any mistakes, I can't see them but my nails look amazing!I will 100% be buying this regularly

Gorgeous colour and dries so quick!
