The N ^o. 2 Bond Perfector is a bond multiplier NOT a conditioning treatment.

N ^o. 2 is absolutely necessary after every service when using Olaplex as it is a system. N ^o. 1 is meant to help mitigate damage during the color, lightening and relaxing process, however it cannot stop all of it. If it did, you would not get a visible result. N ^o. 2 is not an activator, neutralizer, sealer or conditioner. N ^o. 2 contains the same active ingredient as N ^o. 1. N ^o. 2 finds more single sulfur hydrogen bonds and cross links them back together without color, lightener or relaxers working against it.

This is the second step of the OLAPLEX system, applied at the shampoo bowl.
