How to keep hair from growing on your chest?

Why do you ask?: A woman who's developing hirsutism needs an endocrine evaluation -- there's a tumor or risk of serious endocrine troubles until proved otherwise. A man who's hairy and would rather be smooth does best to shave rather than seek laser or electrolysis removal -- there may be someone special in your future who likes it. "Manscaping" is a huge business here in the US. Enjoy yourself & best wishes.
