There is a really wide range of “normal” body hair. It also changes a lot from one ethnicity to another. The first thing I would think about is how much hair you have in relation to your parents – if it’s pretty similar I wouldn’t be worried at all. Even within families, it can vary quite a bit. If otherwise things are totally fine – you’ve gone through puberty, you’re otherwise healthy, your hair on your head is normal and life is going pretty well, I wouldn’t be worried about it. If these are not the case, I’d probably bring it up with your doctor and get his or her input on the situation.
