Ingredients and their benefits

• Bond Building Technology: This technology patented by Olaplex acts on disulfide bonds, which are essential bridges for the integrity of the hair fiber. It rebuilds these damaged bonds, thus restoring strength and integrity to the hair fiber. It creates a shield around healthy bonds, protecting them from further aggression. By strengthening the internal structure of the hair, it makes it more resistant to breakage and split ends.
