The first step in the system: not just cleansing, but professional fiber preparation and longterm maintenance of hair quality. The formula, enriched with Anti-Metal System and Biomimetic Amino Complex, helps remove copper, iron and limescale deposits that can build up on the hair fiber and interfere with colour, lightening and other technical services. By freeing the hair from metallic and mineral interference, it helps improve purity, responsiveness and shine, preparing the fiber for the FIBER ReBOND method.
