SCIENTIFIC ANALYSIS
// Evidence: Hair dyeing ingredients alter hair color through oxidative dyes (permanent coloring via small molecules that penetrate cortex and oxidize to form larger colored molecules), direct dyes (temporary/semi-permanent coating), or metallic dyes. Oxidative dyeing involves ammonia or ethanolamine to swell cuticle, peroxide as oxidizer, and dye precursors (p-phenylenediamine, resorcinol) and couplers that react to form color.
