Launching exclusively at Look Fantastic, the Olaplex. No. 8 Bond Intense Moisture Mask (£26) is the brand's first at-home treatment mask that helps both hydrate and repair dry, damaged hair. The formula, which is incredibly rich and silky, comes packaged in a mess-free, easy-to-dispense pump, and contains not only the brand's exclusive bond-repairing ingredient (bis-aminopropyl diglycol dimaleate), which helps repair the broken disfulphide bonds in the hair follicle, but also a long list of oils (like avocado and sunflower seed) that help to add moisture and shine throughout. For severely damaged hair, the brand recommends pairing the mask with its No.0 Bond Building Hair Treatment and No.3 Hair Perfector once a week or as needed.
