美国采购需求：护发配方，最佳护发产品，天然护发配方，有效护发配方，干发护发配方，受损发质护发配方

I'm in the process of launching a premium hair care line centered around effective solutions for hair loss, and your Hair Growth Serum caught my attention. I have a few inquiries regarding the product and potential collaboration. Is this serum developed in-house and already registered in the EU, including the necessary Safety Assessment and Product Information File? Are there any other legal requirements I need to know about before selling in Europe? Additionally, do you provide shipping and fulfillment services, particularly for European customers? I'd like to understand your shipping process and whether you ship to other regions as well, like the USA or Asia. On the packaging front, are there alternative bottle designs available, and what branding options do you offer? Would love to get a quote or any initial info you can share. Looking forward to hearing from you!
