Professional Size: 2000 ml / 67.62 fl oz.

Olaplex No. 2 Bond Perfector rebuilds and restores any remaining broken bonds ensuring the strongest, shiniest, and healthiest hair possible. The No. 2 Bond Perfector is a bond multiplier not a conditioning treatment. No. 2 is not an activator, neutralizer, sealer or conditioner. No. 2 contains the same active ingredient as No. 1, but No. 2 finds more single sulfur hydrogen bonds and cross links them back together without color, lightener, or relaxers working against it. No.2 is absolutely necessary after every single service when using the Olaplex system. Also great for use as a cutting lotion or prep for a double process prior to highlights. Use in place of clear or conditioner in direct dyes to dilute down.

Free of silicone, sulfates, phthalates, DEA, aldehydes, and never tested on animals.
