Question: 1 / 400

What is the effect of the oxidation process in hair coloring?

It lightens hair

It develops the color by reacting with the dye molecules

The oxidation process in hair coloring primarily involves a chemical reaction that develops color by reacting with the dye molecules. During this process, the oxidizing agent (commonly hydrogen peroxide) interacts with the dye precursors present in the color formula. This reaction creates new color molecules that become trapped in the hair shaft, leading to a permanent change in the hair color.

This process is essential for both lightening the hair and developing the desired shade. It allows for a range of color results depending on the formulation used and the natural hair color. By understanding this mechanism, cosmetologists can effectively choose the right products and techniques to achieve the desired coloring results while ensuring the hair's integrity is maintained as much as possible.
