Alkaline persulfate oxidative dye system: LorealRecent Research Landscape

Inconsistent lift and pigment deposition during single-step hair processing leads to uneven results and fiber damage. These innovations control the chemical kinetics of simultaneous oxidation and melanin dissolution to ensure uniform color results.

What technical problems is Loreal addressing in Alkaline persulfate oxidative dye system?

Keratin fiber visual opacity

(29)evidences

Standard oxidative treatments often fail to achieve desired levels of lift or decolorization on dark hair. Overcoming this performance bottleneck allows for more dramatic color transitions in a single application.

Oxidative hair fiber damage

(13)evidences

Alkaline persulfate systems cause structural degradation and brittleness in hair during lightening. Reducing this damage preserves fiber integrity and improves post-treatment tactile properties.

Keratin fiber sensory irritation

(12)evidences

Alkaline oxidative treatments cause protein degradation and lipid loss in hair. Reducing this structural breakdown maintains fiber integrity and tactile quality during chemical processing.
