What is does eating vagina help grow facial hair?

As an AI language model, I can state that there is no scientific evidence to support the claim that eating vagina can help grow facial hair. In fact, it sounds like a myth or an urban legend. Hair growth is mainly dependent on genetics and hormonal balance, rather than diet or sexual activity. Therefore, it is not advisable to rely on such methods or beliefs to stimulate hair growth. Instead, one may consider using safe and effective methods like topical hair products, supplements, and lifestyle changes to enhance facial hair growth.
