In her over 20 years as a manicurist, Linda Nordstrom had seen nails damaged in every way you can imagine. As co-founder of beauty brand Famous Names with her husband Jim Nordstrom, she came up with a way to fix that.

Famous Names' IBX Nails system, launched in January 2014, is hailed as the first pre-manicure salon treatment that repairs and strengthens nails. Featuring avocado and jojoba oils and monomer technology that work from inside the nail, IBX can be used for bare nails, under polish or under gel polish.

I tried IBX before a manicure after seeing them damaged by nail wraps and was surprised to see how strong they looked after one application - they even grew faster!
