So it’s not a traditional bond builder 😳? That’s right 🙌 K18 takes hair renewal to the next level. K18 does everything bond builders do, reinforcing disulfide bonds on the x-axis, and goes a step further by also repairing polypeptide (keratin) chain breaks on the y-axis. By going to the innermost layers of hair, biomimetic hair science can renew hair’s core strength + elasticity to bring damaged strands back to their original, youthful state. Woah!! 📷 credit @k18hair #k18hair #k18results #bondbuiler #hairtreatment
