January 2006 This study found that keratin fibers like human hair undergo thermal and mechanical transitions that can help assess changes from cosmetic processes such as bleaching and perm-waving.
This study found that, compared to oxidative treatments, reductive perm-waving more severely impacts the intermediate filaments in European human hair, while both treatments alter denaturation kinetics in a first-order manner.
June 2025 in “International Journal of Cosmetic Science” In this study, researchers developed cationic liposomes encapsulated with keratin to improve the recovery of UV-damaged hair, finding that these liposomes significantly improved keratin penetration and reduced protein denaturation and lipid peroxidation, resulting in smoother hair surfaces compared to keratin solution alone.
February 2025 in “International Journal of Cosmetic Science” This research studied European human hair, finding that cysteic acid and protein carbonylation increased with both chemical and photochemical oxidation. Protein carbonylation was highlighted as a more sensitive marker for photochemical oxidation, providing better in situ visualization of hair damage than cysteic acid.
