Why is Sebiprox not prescription even though it has the same ingredient as Stieprox?

Sebiprox is a cosmetic, not a medicinal product, which means that it has no medicinal properties. The dose of cyclopiroxolamine in Sebiprox shampoo is 1%, which is lower than in Stieprox (1.5%). In addition, in the case of the drug, the action and effectiveness must be proven in studies. Cosmetics are not checked in this respect. The method of product registration is decided by the manufacturer and legal regulations, which may, for example, indicate that a product containing a given substance from a certain, specific concentration must be registered as a medicine.
