Chromophore retention polymer matrices: LorealRecent Research Landscape

Chemical degradation from lightening treatments compromises hair fiber integrity and color retention. These innovations utilize acidic pH-regulated bonding agents to simultaneously repair structural disulfide bonds and lock in specific tonal pigments.

What technical problems is Loreal addressing in Chromophore retention polymer matrices?

Hair color washout degradation

(41)evidences

Pigment molecules frequently wash out or fade rapidly from keratinous fibers. Improving retention ensures long-lasting color vibrancy and reduces the frequency of chemical reapplication.

Persistent artificial hair pigmentation

(28)evidences

Artificial pigments leach from the hair shaft during repeated cleansing and environmental exposure. Preventing this loss maintains aesthetic longevity and reduces the frequency of chemical re-treatment.
