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 what make up each strand of hair, if to many bonds are broken the hair starts to break off. Disulfide bonds are broken via chemical, thermal, and daily mechanical processes. Olaplex is the only product of its kind with 8 worldwide patents publishing soon. Olaplex is free of silicone, sulfates, phthalates, DEA, aldehydes, and is never tested on animals.
