TeraBond™ is a reactive system that covalently bonds to amino acids and keratin fragments in human hair, including broken disulfide linkages, and is a natural, high performing Plex bond multiplier.
Other Plex technology uses controversial ethoxylated chemicals (e.g. diglycol, PEGs) that may contain 1,4-dioxane, but TeraBond does not. It is 100% natural, safe, and renewable.
