For a long time, rumors that "silicone oil clogs pores" and "causes hair loss" have troubled consumers. However, with the further refinement of cosmetic regulations in 2026 and in-depth scientific communication, this cognitive misconception is being shattered. The National Medical Products Administration (NMPA) recently included new silicone ingredients like Polymethylsilsesquioxane/Trimethylsiloxysilicate in the "Inventory of Existing Cosmetic Ingredients," further affirming their role in enhancing product stability and safety. Scientific research indicates that the molecular weight of cosmetic-grade silicone oils (such as Dimethicone) is far larger than the skin absorption threshold, making it impossible to penetrate hair follicles or cause hair loss. On the contrary, in hair care products, trace amounts of silicone oil form a breathable protective film that significantly reduces damage from perming and dyeing. For sensitive skin and oily scalps, the application of volatile silicones (such as Cyclopentasiloxane) achieves a refreshing experience of "oil removal without residue."
