OPI Nail 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

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.

Really nice on the nails, bought this after acrylic damage and it’s done the trick.

As a male - not used to using this type of product. Needed to repair constantly split nails for a more professional appearance. Seems to be working well after 2 weeks.

Can't fault this at all. I've got really brittle nails that split and crack. And I've got ridges on my nails (obvious on my thumbs in these pics, Beau's lines I believe) but this has strengthened them so much. Longer nails than I've had in years. Well worth the money!

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

Have been using this for over a week now and my nails have got worse! I believe this has dehydrated my nails as they are now flaking, splitting and breaking.

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.

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 :)
