Silicones as Conditioning Agents in Shampoos

Both amodimethicone and dimethicone copolyol amine are effective hair conditioners.

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.

This study found that hair treated with shampoo containing water-soluble silicone demonstrated smoother sliding and better detangling, compared to shampoo with water-insoluble silicone, due to differences in conditioning film formation.

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 study found that using a high-viscosity, high-amine-content silicone fluid as a pretreatment can protect hair from bleaching and dyeing damage without affecting these processes.
