In fact, high-purity silicone oil is difficult to be absorbed by the skin and is almost non-toxic. The CIR believes that silicone oil can be safely used in cosmetics, and the limits of use are as follows: In hair cosmetics, the limit value is 80% of the mass fraction (that is, the content of silicone oil accounts for less than 80% of the total mass of hair products) , In other cosmetics, the limit value is 24% of the quality score.


The hydrophobic film formed by silicone oil on the scalp is breathable and will not block the scalp pores. In addition, when shampooing, most of the silicone oil will be rinsed off, and it will hardly remain on the hair follicles, let alone be absorbed by the hair follicles.


Therefore, there is currently no evidence that silicone oil can cause allergies, acne, block scalp pores and cause hair loss.
