How does Olaplex No.4 Bond Maintenance Shampoo work?

Kooplex is a bond multiplier containing a single active ingredient, Bis-Aminopropyl Diglycol Dimaleate. This 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.
