In the past few years, "silicone-free shampoos" swept the entire domestic shampoo market, mainly because CCTV news exposed some international big-name shampoos with silicone oil exceeding the standard.

Therefore, it has been questioned by netizens and has caused quite a lot of problems on the Internet. Dispute. So, are these shampoos showing off under the banner of "silicone-free"?


If you look carefully at their ingredient list, you will find that even without the existence of "polydimethylsiloxane", there are still many synthetic industrial raw materials, which may still damage the hair, so it is difficult to say the so-called "silicone-free" in the end.

Actress Gao Lu once exposed the amino acid shampoo that she has always used, saying that her hair is relatively soft, and it is easy to collapse once it gets oily. The main effect of this shampoo is to control oil and fluffy, and it also has the effect of nourishing the scalp. Li Jiaqi has also pushed hard in the live broadcast room, saying that the fragrance of this shampoo is particularly advanced and can last for up to two days.
