OLAPLEX No.7 Bonding Oil - highly-concentrated, weightless reparative styling oil. Dramatically increases shine, softness, and color vibrancy. No.7 minimizes flyaways and frizz, while providing UV/heat protection of up to 450°F/232°C. Colour instantly appears more vibrant to prolong a salon-fresh finish. Suitable for use on both damp or dry hair, the oil works in synergy with the rest of the Olaplex range to seek out broken bonds in the hair that are caused by chemical, thermal, and mechanical damage.
