Do I need FDA or EU approval to sell a bond repair haircare product?

Bond repair products sold as cosmetics in the US are regulated by the FDA under the FD&C Act — no pre-market approval is required, but good manufacturing practice (GMP) compliance and accurate labeling are mandatory. EU sales require compliance with EU Cosmetics Regulation EC 1223/2009, including a Cosmetic Product Safety Report (CPSR). Your chemist should know both frameworks.
