Many individuals struggle with maintaining nail health due to the high cost of salon visits and the damaging effects of artificial nails. OPI has introduced the Repair Mode Bond Building Nail Serum, touted as the first bond-building serum with Patented Ulti-Plex Technology, priced at £29 but available for £18.56 with a discount code. Users can expect smoother, stronger nails resistant to breakage after just six days of application. This product is particularly praised by those in physically demanding jobs, such as domestic cleaners and gardeners, who reported visible improvements in their nail strength and appearance. The serum is recommended for twice-daily use on bare nails, followed by OPI's Nail Envy, a nail strengthener that claims to make nails 95% stronger in one week. While many users have shared positive experiences, some reviews indicate varying results, with a few not noticing significant changes. Overall, the serum has garnered nearly 600 reviews, reflecting a mix of satisfaction and skepticism among users.
