Olaplex is a paraben-, sulfate,- phthalate-, cruelty- free, vegan bonding system, providing a product line to help you achieve beautiful and strong hair. It contains a patented active ingredient that works on a molecular level to seek out broken bonds in the hair caused by chemical, thermal, and mechanical damage. The in-house treatment restores and repairs those broken bonds in the hair, while the at-home system further reduces breakage to visibly strengthen hair, eliminate frizz, hydrate, and protect. Magic is in these tiny bottles.
