Shadan claims that L'Oreal's products "meet or exceed the safety standards in the more 130 countries in which they are sold," yet there are no safety standards in the United States.

Until these chemicals are banned worldwide, it is up to us to pressure companies like L'Oreal to implement universal health standards.
