Created by two of the top PhD's in chemistry and materials science, Olaplex is the first patented, bond-building technology that relinks broken disulfide bonds caused by chemical, thermal, and mechanical damage to the hair. Olaplex works on every hair type to provide real, structural repair. No.3 Hair Perfector is not a conditioner, it’s an at-home treatment that contains the same active ingredient found in all professional Olaplex products.
