Current studies suggest that polydimethylsiloxane (PDMS) is basically not absorbed by the human skin and gastrointestinal tract, has almost no acute toxicity, has no stimulation effect on the skin, has stimulation effect on the eyes, and can cause mild conjunctivitis or red membrane inflammation. There is no evidence that polydimethylsiloxane has teratogenic, carcinogenic and genetic toxicity. It is reasonable to believe that PDMS will not cause health hazards under the current normal use.






And silicone oil causes hair loss, is not rigorous. It is true that hair loss is caused by the use of shampoo, but it can be caused by preservatives, fragrances, or other surfactants. Silicone oil is only a possibility. If one day you use A brand A product to lose your hair, you will not lose your hair after changing to A brand B shampoo which also contains silicone oil. Do you think it is because of silicone oil? On the contrary, my personal experience is that it is ok to use some shampoo containing silicone oil, but the hair brushes off the ground after using a domestic shampoo without silicone oil.






So the oftly-reported silicone oil that causes hair loss has no scientific basis. When using silicone shampoos that cause hair loss, you need to think about the whole product and not let silicone oil, one ingredient, be the scapegoat.






Although the above is to talk about the safety of silicone oil, but this does not mean that silicone oil is a safe 100% no safety concerns cosmetic ingredients.
