The process of oxidation in hair coloring involves a chemical reaction where the existing molecules in the hair dye interact with oxygen, leading to the breaking of chemical bonds. When these bonds are broken, new compounds are formed, which is essential for developing the desired hair color. This reaction allows the dye to penetrate the hair shaft, altering its structure and creating lasting color.

The addition of oxygen plays a crucial role in this process, as it enables the formation of larger, more complex color molecules that can provide long-lasting and vibrant results. This transformation is what ultimately gives the hair its new color, making the understanding of oxidation fundamental for anyone involved in hair coloring services.
