Sulfinic acid reductive stripping: LorealRecent Research Landscape

Residual synthetic pigments bond strongly to keratin, making color correction difficult without damaging the hair structure. These innovations utilize specific chemical decoloring compositions to selectively break pigment bonds while preserving fiber integrity.

What technical problems is Loreal addressing in Sulfinic acid reductive stripping?

Persistent synthetic hair pigmentation

(30)evidences

Hydrophobic dyes often fail to adhere or remain stable on keratinous fibers during standard coloring processes. Resolving this limitation ensures long-lasting color results and resistance to premature fading.

Hair color fastness degradation

(16)evidences

Chemical color alteration causes protein degradation and structural weakening of the hair shaft. Mitigating this damage preserves hair integrity and improves aesthetic longevity.
