January 2016 in “International Journal of Biological Macromolecules” This study found that enzymatic phosphorylation of hair keratin increased its capacity to adsorb cationic components like methylene blue and may have practical implications for hair care products.
November 2025 in “Advanced Healthcare Materials” This study found that incorporating CTA2-BADG, a modified hair-rebonding compound, into damaged hair significantly improved surface morphology and tensile strength by using charge-conversion chemistry to enhance penetration into the hair shaft.

December 2010 in “Langmuir” Hair fibers interact through classical forces, which are influenced by treatments and products, important for hair care and other applications.
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.
