Olaplex No.2 Bond Perfector 2 Litre

No.2 is not optional, No.2 is absolutely necessary after every single service when using the professional Olaplex system. No.1 helps mitigate damage during the colour, lightening and relaxing process, however it cannot stop all of it. If it did, you would not get a visible result. No.2 is not an activator, neutraliser, sealer or conditioner. No.2 contains the same active ingredient as No.1. No.2 finds more single sulfur hydrogen bonds and cross links them back together without colour, lightener or relaxers working against it. This is the second step of the Olaplex system, applied at the backwash.
