Metal that can accumulate inside the fiber can create both a risk of breakage and can negatively impact colour results during colour, balayage and lightening services. This excess copper inside the hair fibre can interfere with the oxydant during the colour service. This means the oxydant may not be able to do its job properly. This patented technology is concentrated with Glicoamine 10% a molecule small enough to penetrate and neutralize metal INSIDE the fiber.
