Premature oxidation and rapid color degradation of dye molecules during application. Preventing uncontrolled chemical breakdown ensures consistent coloring results and prolonged shelf life.

Traditional alkaline oxidation dyes cause structural degradation and scalp irritation. Reducing chemical aggression while maintaining color efficacy prevents fiber brittleness and protein loss.

Poor diffusion of large dye molecules into the keratinous cortex limits color intensity and longevity. Enhancing penetration depth ensures uniform pigment distribution and resistance to washing.
