community Why is Kopexil (trade name Aminexil) not approved as a drug in the US and Europe?
Kopexil (Aminexil) is not approved as a drug in the US and Europe because it is marketed as a cosmetic, which requires less testing and regulation. L'Oreal's 1.5% Aminexil is noted to reduce hair shedding, but its efficacy as a drug is not proven.
