IBX is a professional strengthening treatment that works inside the nail structure, using Interpenetrating Polymer Network technology to toughen and fortify nails from within — making it particularly effective for reversing damage caused by gel polish and acrylics. Miracle Repair is N.Bar's own exclusive treatment that takes things a step further. Combining IBX technology with conditioning oils and gentle heat, it smooths over cracks, gaps, and ridges to create a protective shield against future damage. It helps natural nails grow and strengthen, improving the appearance of weak or damaged nails, and better protecting them from processes like gel removal. Both treatments work beautifully together, and your technician can recommend the right approach based on the current condition of your nails.
