Olaplex is a bond multiplier containing a single active ingredient, Bis-Aminopropyl Diglycol Dimaleate. Olaplex works by finding single sulfur hydrogen bonds and cross linking them back together to form disulfide bonds before, during and after services. Disulfide bonds are broken via chemical, thermal, and mechanical processes.

Bonds break when exposed to chemicals in colour, from heat, and mechanical force such as combing wet hair.

Olaplex is free of silicone, sulfates, phthalates, DEA, aldehydes, gluten and is never tested on animals.
