January 2009 in “Journal of S C C J” This study investigated the effect of peracetic acid treatment on hair fiber structure and found that disulfide bond oxidation altered thermal properties while preserving the α-crystal structure, suggesting different stabilizing interactions in hair fibers.
This study found that a bio-based repair solution containing hydrolysed wool keratin, serine, and transglutaminase improved the physical and chemical properties of damaged hair, increasing its strength, flexibility, and thermal stability while offering long-lasting protection against chemical damage.
This study found that modern styling cosmetics can significantly alter hair structure through changes in interfacial chemistry and cohesion, particularly when applied to already damaged hair.
November 2011 in “Advanced Materials Research” This study found that adding hair fibers to friction materials increased their friction coefficient stability and impact strength while decreasing wear rates, with 1% hair fiber content notably improving performance.
