August 2021 in “Cosmetics” This study identified an optimal sulfate-free and silicone-free conditioning shampoo formulation using 1% hyaluronic acid at 800 kDa, 10% acidic sophorolipid, and 1% sodium chloride, which maintains essential conditioning and cleansing properties without compromising on performance.
February 2026 in “Journal of Surfactants and Detergents” In this study, researchers synthesized new surfactants with hair repair properties, finding that they effectively restored the hydrophobic barrier of damaged hair and improved combing ease compared to untreated hair, highlighting their potential in haircare products.

March 2010 in “International Journal of Cosmetic Science” This study explored how silicones influence the interaction between hair fibers and their impact on hair volume under high humidity conditions.
September 2025 in “International Journal of Cosmetic Science” This study found that for straight hair, friction mainly influences fragment formation during combing, suggesting no direct connection to tensile fatigue failure, while with textured hair, combing performance may be more complex.
October 2025 in “International Journal of Cosmetic Science” This study found that longer-chain cationic surfactants like BTMC provided superior hair conditioning by reducing combing forces, but did not reverse oxidative hair damage, emphasizing the role of molecular structure in surfactant performance.
