Protective And Restorative Effects Of A Bio-Based Crosslinking Complex On Chemically Damaged Hair

The study evaluates a Bio-Based Crosslinking Complex (BCRC) composed of itaconic acid, arginine, D-panthenol, and polysaccharides from linseed and chia, designed to protect and repair chemically damaged hair, particularly from bleaching. BCRC was tested as both a protective agent in bleaching mixtures and a repair treatment in leave-in conditioners. Results from tests on 50 samples showed significant improvements in mechanical strength, thermal stability, shine, and combability of treated hair compared to untreated hair. BCRC-treated hair exhibited a 19.58% increase in tensile strength, restoring up to 92% of the original strength of virgin hair. These findings suggest BCRC's dual functionality as a promising protective and restorative agent for chemically treated hair.
