What are Olaplex and K18?
Olaplex: Bond Rebuilding Technology
Olaplex No.3 is a pre-shampoo treatment that is designed to rebuild broken disulfide bonds in the hair. It contains a patented ingredient called Bis-Aminopropyl Diglycol Dimaleate, which is responsible for repairing these bonds. This technology has gained a cult following in the hair care industry for its impressive results in restoring damaged hair.
K18: Biomimetic Peptides for Bond Repair
K18, on the other hand, uses a different approach to repair damaged hair. Its key ingredient is the K18Peptide™, which repairs broken polypeptide chains in the hair. This biomimetic peptide technology mimics the natural process of hair repair, resulting in stronger and healthier strands.
