Keratin Preservation - Oxiproteomics

Efficacy Testing for Keratin Preservation

Keratin is the primary structural protein of hair, responsible for its strength, elasticity, and resilience. However, daily stressors—including UV exposure, pollution, heat, chemical treatments, —progressively degrade keratin, leading to weakened hair fibers, breakage, and loss of shine. Preserving keratin is essential to maintaining hair integrity and long-term health.

At OxiProteomics, we provide advanced efficacy testing to scientifically validate your product’s ability to protect and reinforce keratin. Using cutting-edge protein analysis and amino acid quantification, we assess how formulations:
✔ Prevent keratin degradation and oxidative damage
✔ Strengthen hair fibers for improved resistance to daily stressors
✔ Maintain structural integrity to keep hair healthy and vibrant

With our scientifically backed approach, we help you substantiate strong, credible claims on keratin preservation, setting your hair care products apart in a competitive market.

KERATIN damage; cuticle damage; cortex damage;

EXPLORE OUR INNOVATIVE TESTING

Hair fibers exposed to urban pollution suffer oxidative damage, leading to weakened keratin, breakage, and dullness. Our study compares hair fibers with and without a protective product, demonstrating how active formulations shield keratin from oxidation, preserving hair strength, integrity, and shine

WHO WE ARE

OxiProteomics is a CRO specialized in biomarker assessment providing research services for skin- & hair-care dermo-cosmetics, food supplements, medical devices, and dermatology efficacy evaluation.

Spined-out from Sorbonne University in 2014, our uniqueness is a specific know-how on non-targeted & targeted proteomics approaches adapted to skin and hair evaluation. We support our clients on molecular target identification, target validation, efficacy testing, mechanistic studies, prediction of responders, and biomarkers discovery.

We also propose predictive pre-clinical skin models coupled with spatial proteomics analyses, based on the organ culture of human skin samples. We also able work with clinical samples to perform bio-analysis. We also provide mechanistic investigator-initiator trials with the analysis of biopsies and non-invasive samples.
