The process of hair lightening is known as decolorization. This technique involves using chemical agents, typically hydrogen peroxide or ammonia, to lift the natural pigment from the hair shaft, resulting in a lighter color. Decolorization alters the hair's internal structure, allowing professionals to achieve a wide range of lighter shades, from subtle blondes to more dramatic platinum tones.

This process is essential for creating various hair color effects, as it prepares the hair for additional coloring or styling techniques by ensuring an even base. Understanding decolorization is crucial for cosmetologists, as it affects how well hair can receive additional pigment or how it will behave after the lightening process.
