The hair formula shampoo sold by Pinduo is fake and exists. Pinduoduo is true or false, buy things according to the price. Don't buy too cheap shampoo. It must be fake. If you want to buy, you'd better choose the official flagship store. There is still some guarantee for buying shampoo there, and there is also genuine guarantee. The kind of shop that gives a fake and ten penalties is generally not fake. After all, he has trust. But there are some shampoos with different brands, and the quality is definitely good or bad. You have to buy them by your own luck.
