加拿大采购需求：护发产品制造商、自有品牌生发精华液、自有品牌护发产品、自有品牌美发产品

I'm on the lookout for a water-based hair serum or drops specifically designed for promoting hair growth and addressing thinning hair. I'm not interested in oil-based products, as I prefer something lightweight and easy to apply. It would be great if the formulation includes ingredients like biotin or minoxidil, but the most crucial factor is that it must be FDA approved since I intend to market it in Canada. Could you please check if you have any products that match this description? I'm eager to hear about any options you might have and to understand their ingredients and benefits. Looking forward to your prompt response!
