Olaplex is a bond multiplier, a serum that is added to the color and applied, as a quick and easy one-step treatment. This allows the hair to be repaired internally, replacing the bonds that are sometimes broken during the color service. This allows the colorist to push the envelope and give you the hair you always dreamed of. Blondes can be blonder, balayage can be lighter and brunettes and redheads can have more strength and longevity. It also works as a reset button for hair that is damaged due to: previous color services, heat damage, medication, stress, or everyday free radicals. This treatment is necessary for every hair type, even men’s hair too!!
