AI Technical Summary
Technical Problem
Existing hair coloring methods, particularly oxidative dyes, result in long-lasting but damaging hair color with unpleasant odors, while direct dyes provide less durable color that washes out quickly, and there is a need for high wash and rub fastness without using oxidation dye precursors.
Method used
A two-agent process for dyeing keratinous materials, where agent (a) contains organic silicon compounds and agent (b) contains effect pigments and a film-forming polymer, applied to achieve high color intensity and fastness.
Benefits of technology
The process results in keratinous materials with particularly intense and durable color nuances, maintaining color integrity through multiple washes without damaging the hair.
