It is often reported that silicone oil causes hair loss. When silicone oil is used in shampoo, the pores will be blocked by silicon. If the pores are blocked, the sebum will not flow out. The sebum trapped in the pores can be made vigorously, causing redness, inflammation, acne and hair loss
In fact, there is no corresponding scientific basis, and healthy scalp is more suitable for shampoo containing silicone oil. "Silicon oil free" is more suitable for some specific people, such as friends with thin hair, short hair and sensitive scalp. Because it can make hair fluffy and not easy to be allergic, of course, it may cause dry hair.
