OPI Nail Envy Nail Strengthener, Original Clear Nail Polish Treatment with Vegan Formula to Strengthen Weak & Thin Nails, 15ml

Used frequently for months, and it really strengthens nails while providing beautiful colour. Very pleased with the quality and performance. Seemed to last a long time and was overall chip resistant. Nothing major to dislike. Better than competitors in terms of colour and nail care.

I love this range of nail polish but wish they'd bring out more choices for colour. This colour is lovely for autumn and winter, it chipped each day which wasn't great. When I put opi plump effect top coat on though it lasted for 6 days! Quality is ok bit not sure about value for money.

Works well, but not perfectly. Apply 2 coats on the first day, then relax with a book (or g&t) for a good 30 minutes. There may be tiny chips during the next 24 hours, but if you reapply a coat, as per the instructions (and let it dry/ cure for 20 mins), it'll look perfect again. Elegant nude varnish which strengthens nails. NB: There are some nail traumas which a strengthener can't help with :-).

I'm blown away by the difference in my nails after using this. My nails were so incredibly weak, it was impossible to grow them at all as they were so soft. They had to be filed right to the nail bed. I'm not exaggerating at all when I say my nails were weaker than paper. I'd tried oils and treatments for the last 2 years with no success. I've used this for about 10 days now and the difference is insane. They're so much stronger, even when I remove the product, that it's a similar level of strength to when I use UV gel - maybe slightly softer than when it's builder gel but definitely stronger than when wearing regular UV gel polish. Im so shocked by how much stronger and less bendy they are, I am actually growing them without them tearing, without needing gel overlays for strength! The polish does peel a lot - I had to touch up quite often as it lifts easily - so I definitely wouldn't use it as a base coat - but as a strengthening treatment I cannot recommend highly enough.

I buy this frequently as my nails are prone to breaking due to having to manoeuvre my work rucksack and my dog sometimes, resulting in my nails getting caught on eg. the dog lead then breaks. Not sure if they changed the formula but it’s really streaky now and been with 2 coats, it’s not looking great. It also bubbles up when drying sometimes, leaving my nails looking terrible. It peels easily too and it get gloopy really quickly. So I’m no longer a fan as my nails are not as strong either, breaking easily at the tips.

This OPI Nail Envy nail strengthener is great — it dries quickly, making it easy to use, and I’ve noticed my nails feel stronger and healthier since I started using it. The clear formula is perfect for everyday wear, and it’s a high-quality product. Highly recommend!

I bought two different brands to do a proper comparison. Nails on both hands started off very weak, breaking easily. 3 weeks later, following all instructions and my right hand treated with this OPI product is in worse condition than when I started. Peeling, snapping and very dry. Conversely, my left hand treated with active bright by manicurist has vastly improved - stronger, no striations and as a result has grown much longer. On this basis, I highly recommend not buying this product because it's not only expensive but it doesn't work at all and may in fact be detrimental. Oh and whilst the colour was nice, it chipped within a couple days. First three pics show my right hand treated with OPI and last two are other product. It doesn't show up too well in pics but the difference is vast.

I’ve struggled with weak, brittle nails for years, but OPI Nail Envy has been a real game changer. After using it consistently for a few weeks, my nails feel noticeably stronger and less prone to splitting or peeling. The formula is lightweight and easy to apply, with a smooth finish that doesn’t yellow my nails like some other strengtheners I’ve tried. I also like that it works well as a base coat under regular polish, giving my nails extra protection. The bottle size lasts a long time since you only need a thin layer each time. Overall, OPI Nail Envy is one of the best nail strengtheners on the market and definitely worth the investment.
