What Is Olaplex Bond Building Technology®?
Olaplex's patented Bond Building Technology® works at a molecular level — finding and repairing broken disulfide bonds within the hair structure that are caused by chemical, thermal and mechanical damage. Unlike conditioning treatments that simply coat the hair surface, Olaplex genuinely repairs the internal structure of damaged hair — delivering results that no other brand can replicate. It is the most clinically proven hair repair technology ever developed.
