I am a 26 yr old male. What can I do to get hair on my chest and increase my facial hair growth?

It's genetic. About 5% of men never get chest hair or a good beard. Many (maybe most) women in the us claim they actually prefer this, and such men usually don't have any male pattern baldness. Paul newman, the first hollywood star with really good muscle definition, mentioned having no chest hair and nobody's claiming it detracts from his looks. Embrace what you've got ; who you are, smooth guy.
