Final answer:
High-lift tints are mixed with a developer to lighten the hair by lifting its natural pigments. The developer is typically hydrogen peroxide, and this combination is used for permanent hair coloring.
Step-by-step explanation:
High-lift tints are designed to achieve lighter color in hair by lifting the natural pigment. These tints are typically mixed with a developer, which is often hydrogen peroxide. The developer helps to open the hair cuticle and allows the tint to penetrate the hair shaft, thereby lightening the hair. High-lift tints are a form of permanent hair coloring that includes three essential components: an oxidative dye, a coupling agent, and an oxidant, which works under basic conditions to lighten hair.
The mechanism through which high-lift tints work involves the oxidation of a diaminobenzene derivative to a quinone state, followed by a reaction with a coupler compound, and then a final oxidation step to yield the desired hair dye.
