Hair Growth Remedies

I have excessive body hair, I am asian and both of my parents don’t have much body hair. I read somewhere that lack or excess of certain vitamins or minerals increase body hair growth, can you tell me which increase body hair growth so I can avoid them?

You’re supposed to apply hair removal wax in the direction the hair growth is in, and pull against the direction of hair growth. I want to know how you can determine what the hair growth direction is.
