Decolorization in the hair coloring process specifically refers to the removal of natural pigments from the hair. This process often involves using a bleaching agent to lighten the hair and prepare it for subsequently applied colors. It is an essential step for achieving lighter shades or for creating a blank canvas before adding new colors, particularly if the goal is to significantly alter the hair's original shade.

Other options relate to different aspects of coloring hair. For instance, intensity of the color applied pertains to how vibrant or muted a dye appears but does not address the removal of pigments. Mixing different dyes refers to creating custom shades or blends, which also does not involve stripping the hair of its natural color. The application of toner is a separate step that can be used after decolorization to neutralize unwanted undertones or to enhance the final color, but again, this does not encompass the decolorization process itself. Therefore, recognizing decolorization specifically as the removal of natural pigments helps clarify its unique role in hair coloring.
