OPI's Repair Mode Bond Building Nail Serum, described by shoppers as a 'wonder product' for weak and flaking fingernails, has been reduced to £24.65 in the brand's early Black Friday sale, down from its usual £29 price.
The serum, which the brand says can revive nails in just six days, uses patented Ulti-Plex Technology to rebuild broken keratin bonds deep within the nail rather than simply coating the surface. According to OPI, applying it twice a day for six days delivers 99 per cent keratin repair and a noticeably smoother texture.
Bundle deal and alternatives
For additional nail and cuticle care, OPI's Care n' Repair Bundle is also discounted by £10 to £54.74. The kit includes the Repair Mode serum alongside the Good As Gold Cuticle Serum and Nail Envy strengthener, targeting brittle edges while nourishing skin and shielding nails against cold-weather damage.
OPI explains: "Together, they help repair, strengthen and nourish so your nails can look and feel their best. Think less breakage. More strength. All the shine."
Shoppers looking for cheaper options can consider Manucurist's 3-step Repairing Care kit, available at Space NK for £15.20 down from £19, or the Essie Hard to Resist Advanced Nail Strengthener, reduced from £10.99 to £8.79 at Lookfantastic.
Shopper reviews
Customer feedback has been largely positive, with one shopper admitting initial doubts before trying the product. They said: "I was sceptical, but after using as directed for 7 days, my nails have been transformed."
Another reviewer described their experience: "My nails were in a terrible state. Nails were thin to the point that the fleshy bed was showing, and the nail was not growing over it. Tried strengthener polish, cuticle oils, everything, but my nails just weren't growing over the visible fleshy nail bed. Repair Mode was recommended to me, and I started using it a week ago, twice a day (morning and before bed), and I can see visible improvements already."
One customer who had previously used BIAB praised the serum as a strong foundation for natural nail regrowth, while another noted: "The Repair Mode Bond Building Nail Serum has been amazing at strengthening and stabilising my split and peeling nails. From the very 1st coat, you can feel the difference. Really easy to apply, quickly absorbed, and dries. I would recommend this to anyone who has weak and split nails."
Not all reviews were glowing, however, with one three-star reviewer stating: "I have used this product twice a day for 6 days, and it has not made any difference to my nails."
Despite this, the majority of customers were impressed, with one review summing up the sentiment: "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 anyway, but the wait was worth it when using this serum."
