Which type of tint is made from oxidative dyes?

The type of tint made from oxidative dyes is para tint. Para tints, also known as permanent hair colorants, contain para-phenylenediamine (PPD) and other chemicals that undergo a chemical reaction upon application to the hair. This reaction occurs when the oxidative agents, typically hydrogen peroxide, are mixed with the dye precursors, allowing the tint to penetrate the hair shaft and develop into a long-lasting color.

The nature of oxidative dyes allows for a wide range of colors and the ability to achieve full coverage of gray hair, which is a significant advantage of para tints over other types of hair color products. The other types mentioned do not employ oxidative dyes: direct dyes are ready to use without a separate mixing process, vegetable colors are derived from plant sources and do not use chemical oxidation for the coloring process, and frosting tints are often more related to highlighting techniques rather than the development of permanent color through oxidative means.
