Already sworn your allegiance to the OLAPLEX line-up? Allow us to introduce you to our latest obsession, the No 8 Bond Intense Moisture Mask: a highly concentrated treatment that not only moisturises and smooths your strands but also adds body and light-scattering shine in just 10 minutes. Made with an airless pump for measured dosing and a potent formula that packs a punch from the first use, this 4-in-1 reparative mask will have you on your way to beautifully smooth, healthy-looking hair. At the heart of the formula is the brand's star ingredient bis-aminopropyl diglycol dimaleate – sounds science-y but it works to restore and repair chemical-treated, heat-ridden hair. Working its magic on all hair types and textures – as the whole OLAPLEX line does – this mask works even if you’ve never tainted your locks with colour or tongs, but it's most beneficial to intensely damaged lengths. How to use: Apply to clean, damp hair mid-length to ends. Use sparingly on the roots. Work through with fingers. Leave on for 10 minutes. Rinse fully and style as usual. Start with 2 pumps for shoulder-length hair. Use more for longer, thicker hair. Less for fine or short hair. Use weekly for best results. For the deepest repair possible at home, use with No.0 Intensive Bond Building Hair Treatment + No.3 Hair Perfector once a week or as needed.
