Olaplex is the only Bond Multiplier out there and relinks broken disulfide bonds and prevents Cysteic Acid from eating the protein out of the hair. Olaplex owns 8 world patents on the technology of it.
b3 is a deep conditioner.
Here is what its ingredients do to the hair.
B3 Brazilian Bondbuilder:
Dimethyl isosorbide is a water miscible organic solvent. PPG-3 Benzyl Ether Myristate is an artificial oil used as a silicone replacement. Hydrogenated Castor Oil / Sebacic Acid Copolymer is an oligo ester for coating hair and does not repair bonds. It’s similar to silicone and but heavier. Benzyl alcohol is used as a solvent. Tocopherol acetate is a vitamin E acetate. Tocopherol phenol is a vitamin E derivative. Beyond these, you have 4 different oils including organ, jojoba, sunflower and apricot that will just coat the hair as well as many herbal extracts that add nothing to the chemistry. Brazilian Bond Builder is an oil-based product consisting of artificial and natural oils dissolved in artificial solvents and is incapable of rebuilding broken bonds in the hair. It also contains low concentrations of vitamin E derivatives, herbal extracts, and fragrances.
(B3 does not eliminate free radicals. Olaplex does work throughout the hair. It’s not just internal. Sulfur hydrogen’s or free thiols are present on the surface of the hair and Olaplex links them.)
