September 2023 in “International Journal of Cosmetic Science” The researchers reported that adding specific combinations of hydrolyzed proteins to silicone-free shampoo improved hair conditioning properties by reducing friction and increasing surface adsorption and penetration into hair, compared to protein-free alternatives.
This paper highlights the significant role of silicones in hair conditioners, noting their ability to enhance smoothness and manageability while also protecting against damage. The authors emphasize the growing importance of developing silicone-free, eco-friendly alternatives to meet evolving consumer preferences.
