Long and robust nails often seem like a challenging goal, prompting many to turn to a nail strengthener that one customer described as making a 'major difference' to their 'awfully fragile' nails. The OPI Nail Envy Strengthener has been upgraded with a new vegan formula and a range of colours to choose from.
Price and Availability
The strengthener is currently priced at £14.72, reduced from £23, on the OPI website, using the code treat20, which is valid until June 23 at 11:59pm. Among its most popular shades is the OPI Classic, which offers a sheer, shiny finish.
Colour Options
It is available in eight additional colours: a sparkly midnight blue, white, red, beige, dark pink, maroon, and two variants of sheer pink shades.
Key Ingredients and Technology
The formula features Tri-Flex Technology, which creates a liquid shield over the nail to build strength layer by layer. Combined with biotin, calcium, and vitamins A, C, and E, the treatment helps guard against chipping, peeling, and splitting while supporting overall nail health.
Application Routine
The recommended routine is straightforward: apply two coats on day one, then one coat daily for five days, before removing and repeating the cycle. For optimal results, it can be used with Repair Mode as part of a comprehensive nail care routine.
Effectiveness
According to OPI, nails can become up to 95% stronger in just one week of continued use, making it a popular choice for those seeking to improve nail condition without complicating their routine.
Customer Reviews
Shoppers have given the OPI Nail Envy Strengthener outstanding ratings. One customer said: 'I have been using this for a month now because of the rave reviews! It's a freaking miracle in a bottle. I used the Seche Vite Fortified Nail Strengthener before this and was VERY disappointed. But Nail Envy is amazing! I'm so impressed by how well it actually works. My nails no longer bend like paper. What a marvellous product! This is the longest my nails have been in years and they haven't broken AT ALL, compared to breaks every few days without it. I follow the directions exactly: 2 coats on day one, then one coat every other day for a week, remove and repeat.'
Another added: 'This nail strengthener does exactly what you're hoping it would do. It not only provides a heavy layer of protection when doing any sort of task, but it acts like a shield so my nails don't snap. The natural shade also looks great. It's extremely easy to apply and dries remarkably fast. I highly recommend this product if you need a serious nail shield!'
While some customers deducted a star, one remarked: 'A great colour but not quite as good a finish as The Original Bubble Bath. Please bring it back.' On the whole, the majority of buyers were satisfied, as demonstrated by another customer who noted: 'I have awfully fragile nails, but I noticed a major difference within a week of using this stuff. I had a severe peel on my middle finger from banging it on a metal fixture on Day 2. I just coated more Nail Envy over the raw edge. Within just a few days, the surface smoothed over completely and it looked like the peeling layers were literally fusing back together. By day 10, my nails were entirely flexible, shock-resistant, and just kept growing and growing.'
Alternatives
As an alternative, Lookfantastic stocks the Mavala Scientifique K+ Nail Hardener for £21, which is formulated to visibly fortify weakened nails. A more budget-friendly option is the Boots Nail Strengthener 10ml for £6, suited to dry, lacklustre, and fragile nails, delivering a long-lasting glossy finish.
The full range of Nail Envy Strengthener shades is currently available from OPI at a reduced price using the promotional code treat20.
