Silicone oil = polydimethylsiloxane

On most shampoo recipes there is a "polydimethylsiloxane", which is what we often call silicone oil. When shampooing with silicone oil shampoo, because silicone oil is insoluble in water, the hair scales will be wrapped in the hair scales when the silicone oil is opened, filling the cracks in the hair scales will create the illusion of suppleness. But this kind of package is not one-off, but accumulated one by one. Over time, the hair is "pressed down" by thick layers of silicone oil, losing its elasticity, and the hair follicles are blocked and unable to metabolize normally. Hair follicles are "stuffy and thirsty". Hair is bound to be dry and damaged, even worse, causing hair loss.
