Is there anything i can take to increase your body hair growth?

Not really.: Body hair growth is largely determined by genetics. Applying rogaine (minoxidil) miight help a little. Taking testosterone would might work but you would have severe side effect, acne, oily skin, deep voice, loss of breast mass, enlarged clitoris, etc. Assuming your are a female as indicated in your profile these would be intolerable. Most women don't want body hair! if you are male, ask again.
