A host of miraculous components that strengthen damaged bonds unite to create Olaplex No. 3 Hair Perfector. The bestselling at-home pre-wash treatment restores healthy shine and soft texture to dry, damaged hair with a bond-building patent known as ‘bis-aminopropyl diglycol dimaleate’. It realigns broken disulphide bonds in the hair structure, repairing strands weakened by heat styling, frequent colouring, brushing and UV exposure. Comb the Olaplex hair treatment through damp hair, allow it to work its magic for 10 minutes, then follow with your usual wash routine. Hair will feel strong, shiny and velvety-soft. Free of DEA, aldehydes, formaldehyde and Butylphenyl Methylpropional (Lilial). Set Contents: Olaplex No. 3 Hair Perfector 2 x 100ml | Olaplex No. 3 Hair Perfector Duo | Dermstore
