hello, l' oreal silk spring moisturizing hair mask. 1. the genuine products are exquisitely packaged, and the fonts are clearly printed, and there will never be any misprints, pastes and the like. 2, genuine anti-counterfeiting trademark ciq logo, production date and so on. (However, it is not excluded that some unscrupulous merchants recycle genuine packaging and put it into imitations.) 3. The production of the white cover inside the genuine product will not produce burrs and other phenomena. 4, the authentic smell is natural and fragrant, not the smell of chemicals, nor the messy smell of cream. (Some unscrupulous merchants will directly cheat, while others will be half miserable and half fake, but the taste will be greatly reduced, and there will be no such natural fragrance.) 5. The genuine product is not so thin, even if the bottle is turned upside down, it will not fall out.
