Science
Mechanism of Action
This cationic polymer functions via electrostatic attraction, binding to the negatively charged keratin structures of hair and the surface of the skin. Upon application, it deposits a coherent, uniform polymeric film. This film acts to neutralize static charges, thereby reducing static electricity, and contributes to a significantly smoother and softer tactile finish on the treated surface.
