A woman who decided to abandon false nails after two decades has discovered a serum that she describes as 'incredible' for bringing her natural nails 'back to life.' Beauty enthusiasts who have switched from salon treatments are raving that their nails 'have never been as strong, are smooth and look super healthy' after using this product.
OPI's Repair Mode Bond Building Nail Serum
Damaged nails can be uncomfortable and unsightly, but with our hands often enduring strain from daily tasks, signs of wear and tear are common. Now, beauty lovers are praising a bond-building nail serum they call a 'game changer.' OPI's Repair Mode Bond Building Nail Serum with patented Ulti-Plex Technology penetrates the nail's surface to build new bonds from within. The product normally retails for £29, but at the time of writing is available in the brand's spring sale for £20.30. Shoppers can also use the code TREAT20 for 20% off, bringing the price down to £16.24, though the code expires on May 31, 2026.
Customer Reviews
The product has amassed plenty of fans online, with OPI customers leaving rave reviews. OPI says that when used as directed, nails look improved after the first application. After six days of use, users can expect smoother, stronger nails that are resistant to breakage, along with an improvement in the appearance of ridges. One fan of the serum said in a lengthy review: 'Amazing product. I've had all sorts of fake nails over 20 years, it got to a point where it started to be painful having them done. But, my nails have always been weak and looked awful. So, I covered them up with nail varnish, also used lots of other products that promised to help my nails, but they all made it worse. Then, whilst browsing through endless treatments, I see OPI repair in Boots, and yes, it's slightly expensive. What a find, it's an amazing bottle of excellence, and after two weeks of using it my nails are changing, coming back to life.'
A second reviewer raved: 'Wow. Bought last week and have used for 6 days, can already see a vast improvement in my nails, despite swimming most days. Very impressed and relieved!' A third said: 'Nail game changer. Worth every penny. Incredible product - nails have never been as strong, are smooth and look super healthy. I invested in this product after giving up having my nails done in a salon (BIAB), so they were weak and damaged. The bottle is about half the price of a professional mani, with the benefit of getting your own lush, natural nails instead of plastic coated ones. Results were apparent within a week and I've kept up the recommended twice-daily application to get the best results. Love how quickly it dries too - no faffing about waiting for it to dry.'
However, not all feedback was glowing. One user noted: 'Tried due to hype. It's okay, I haven't noticed anything specific; I won't be buying again, it's a shame.' But another commented: 'A wonder product, much needed by many of us with weak, flaking fingernails. The serum is easy to apply and dries straight away. It does take time for nails to grow, but the wait was worth it when using this serum.' A further review reads: 'Been using this for a couple of years now. I have never been able to grow my nails. This really fixes my splitting nails. Ordered another as I have worn acrylics for 2 months; after just 7 days my nails are looking normal again.'
Alternatives to Consider
If OPI's offering doesn't suit, those with weak nails may wish to opt for the NAILS.INC Back To Life Strengthening Nail Treatment, which costs £15. It is enriched with five reviving oils to help repair and add glow to lacklustre nails. Meanwhile, Sally Hansen's Miracle Cure Nail Strengthener is normally priced at £11 but is currently on offer for £8.80 at Boots. It helps reinforce nails, prevent peeling, and seal the nail plate. OPI's Repair Mode Bond Building Nail Serum isn't the brand's only popular treatment. The Nail Envy Strengthener comes in a sheer colour and uses Tri-Flex Technology to strengthen and protect nails against chipping, peeling, and splitting. Usually retailing for £23, at the time of writing it is £16.10 on sale.
