Ingredients and their benefits

• Bond Building Technology: This patented technology by Olaplex acts on disulfide bonds, which are essential bridges for the integrity of the hair fiber. It rebuilds these damaged bonds, restoring strength and integrity to the hair fiber. By strengthening the internal structure of the hair, it makes it more resistant to breakage and split ends. Olaplex's patented bond-building technology penetrates at the molecular level in all hair types.
• Bis-Aminopropyl Diglycol Dimaleate: This molecule works in a unique way to quickly and effectively repair broken bonds and restore healthy hair. This active ingredient is included in all Olaplex products, giving them restorative and protective properties.
