Olaplex Back Bar #2 Bond Perfector, 67.62 Ounce

Olaplex No. 2 Bond Perfector is a bond multiplier, not a conditioning treatment. No. 2 Bond Perfector is not optional; it is absolutely necessary after every single service when using Olaplex as a system. No. 1 is meant to help mitigate damage during the color, lightening, and relaxing processes; however, it cannot stop all of them. If it did, you would not get a visible result. No. 2 is not an activator, neutralizer, 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 color, lightener, or relaxers working against it. Olaplex is a single ingredient that is added before and after hair color treatments and other chemical services. It promises to preserve the integrity of the hair and essentially multiply the bonds within the hair shaft. In other words, Olaplex reconnects the broken disulfide sulfur bonds in the hair that were broken down during thermal, mechanical, and chemical services.
