TLDR The study found a green method for strengthening hair works on all hair colors and is eco-friendly.
The cosmetics industry is shifting towards eco-friendly products, including hair products. This study focused on a harmless method of cross-linking hair using eco-friendly chemicals composed of riboflavin phosphate (RFP), citric acid (CA), and polyols. The optimal concentration for maximum hair cross-linking was found to be a combination of CA 3%, isopentyldiol (IPD) 5%, and sorbitol 3%. This combination increased the tensile stress and Young’s modulus of hair by 41% and 44%, respectively. The RFP treatment was applied to black, brown, and blond hair, and it was found that hair color had no impact on the photo-cross-linking reaction. The study concluded that the visible light-mediated cross-linking method can be used for any hair color and is expected to be widely adopted as an environmentally friendly hair care product.
