Im 19 years old still dont hit puberty yet... What should i do ? I have a lil bit of hair in my face .
Welcome to A2A, Reek97. When you say you haven't hit puberty yet, do you mean there hasn't been the normal development of penis, testes, voice, etc? (I'm assuming you are male.) If that's the case it's definitely time to see a specialist.
Or are most signs of puberty OK, except for facial hair? You might just genetically be not very hairy: I knew someone who didn't need to shave daily at 21.
