The Olaplex range has expanded due to its popularity, but it was originally a three step system. Bond Multiplier: Olaplex No.1 called the Bond Multiplier, is applied at the salon, with the bleach, or permanent dye and is a water soluble solution made up of bis-aminopropyl diglycol dimaleate active. Bond Perfector: Olaplex No.2 is labelled the Bond Perfector, containing a smaller amount of the same active ingredients in No.1 mixed with conditioning agents. Step No.2 is also applied in the salon and is considered a post colour salon conditioning treatment. Hair Perfector: Olaplex No.3 is the take home product in the three step process. It is called the Hair Perfector, and contains an even smaller amount of the active ingredients, mixed with mostly conditioning agents. This step should be applied to the hair similar to an at home, leave in conditioner. Olaplex now offers steps No.1 to No.7. All products contain portions of the same active ingredients found in Olaplex No.1, No.2 and No.3, and all have the same claim, to repair broken bonds in the hair.
