In the mechanism of hair dye, potassium persulfate mainly acts as a powerful oxidizing agent. Its core function is to bleach the natural melanin inside the hair through oxidation reactions, thereby creating a foundation for the development of artificial pigments. At the same time, it promotes the reaction of coupling agents, enabling small dye precursors to polymerize into large pigment molecules that remain stable within the hair fibers. This ensures that the final hair color appears more uniform and long-lasting. The purity, activity, and stability of potassium persulfate directly determine the three core indicators of hair dye performance: coloring efficiency (whether it colors quickly and evenly), color durability (whether it resists fading), and the degree of hair damage. Thus, it is an indispensable key component in hair dye formulations.
