What causes women to have facial hair (chin, moustache) is it a food thing?)?
It is hormones. Testosterone is what causes facial hair. You have to remember that both men and women have estrogen and testosterone, but women have more estrogen than men, and men have more testosterone than women. Now, sometimes women have higher than average testosterone levels(or men have higher estrogen levels) which can cause things like facial hair. It is normal, and natural. —- Some men have higher voices, or are more emotional if they have higher than average estrogen levels.
