What is the purpose of decolorization in hair coloring?

Decolorization in hair coloring is primarily aimed at removing natural or artificial hair color. This process is essential for achieving a lighter base before applying a new color, especially if the desired shade is significantly lighter than the existing color. By effectively lifting the color, decolorization allows for a more vibrant final result and ensures that the new color is true to the intended shade.

Removing natural pigments from the hair shaft opens the hair structure, allowing for better adherence of the new color. It is particularly important when transitioning from dark to light colors, as the underlying pigments can affect how the new hue appears once applied.

While adding color to the hair is a subsequent step in the process, decolorization itself is focused on the removal aspect. Enhancing the longevity of the hair color and creating texture may be outcomes or benefits of the overall hair coloring process, but they are not the primary purpose of decolorization. The main goal is to prepare the hair for a new color application by stripping away the existing hues.
