How does Olaplex work?

All hair types (natural, curly, fine, straight, etc.) derive most of their integrity from healthy, properly paired, disulphide bonds. When hair is damaged via thermal, chemical, mechanical or environmental factors, these disulphide bonds are broken apart, resulting in single sulphur hydrogen bonds. In the case of chemical services, Olaplex works by pairing with the single sulphur hydrogen bond faster than the three oxygen molecules can.
