What does "decolorizing" hair involve?

Decolorizing hair primarily involves removing existing pigment from the hair strands using bleaching agents. This process is designed to lighten the hair by breaking down the melanin pigments that give hair its color. When a bleaching agent is applied, it initiates a chemical reaction that lifts the color, making the hair significantly lighter.

Understanding the decolorizing process is crucial for cosmetologists, as it allows them to achieve various hair colors by lightening the base before applying new pigments. The goal is often to create a blank canvas that can then be tinted or colored in desired shades, particularly when working with vibrant or fashion colors that require a light base to show up clearly.
