Dramatically repairing, protecting, and strengthening tresses, OLAPLEX’s formula works at a molecular level to repair broken bonds. That’s where the N°7 Bonding Oil comes in. Designed to increase shine, softness, colour vibrancy, and manageability, the vegan, highly concentrated oil minimises flyaways and frizz while protecting locks from heat reaching up to 450°. Pretty incredible, right – we certainly think so.
