Sequential oxidative dye layering: HenkelRecent Research Landscape
Conventional hair dyes rely on harsh solvents and oxidative damage that degrade fiber integrity. This lever utilizes chitosan-pigment binding to stabilize colorants on keratin surfaces without solvent-driven degradation.
What technical problems is Henkel addressing in Sequential oxidative dye layering?
Unnatural flat hair color
(27)evidences
Pigment-based hair colorants suffer from rapid degradation and removal during routine cleansing. Addressing this instability ensures long-term color integrity on keratin fibers.
Poor dye wash fastness
(16)evidences
Keratin fibers suffer from rapid pigment loss and leaching during repeated washing cycles. Improving pigment retention ensures long-lasting aesthetic results and reduces the frequency of chemical re-application.
Poor color wash fastness
(6)evidences
Insufficient pigment retention and rapid fading during subsequent washing or environmental exposure. Enhancing dye durability ensures long-lasting aesthetic results on keratin fibers.
Keratin fiber tactile degradation
(2)evidences
Keratinous fibers suffer from rapid pigment loss and wash-out due to weak dye-substrate adhesion. Enhancing durability through moisture-curable barriers prevents premature color degradation.
