I am 19 years old and i cannot grown any facial hair at all?

Why do you want to be a hairy fella who has to shave everyday, its a blessing that you dont have hair growth. But anyways if being hairy with stubble is your thing, eat a lot of bananas and drink milk, the ingridient potassium in them will push your testosterone production to overdrive making you the hairy ugly fella you crave to be.

It is du to some defect in manly Hormones . If u want have hair , see a doctor

Don't worry about it chief, think of all the money you are going to save by not having to buy razors. Besides shaving every day becomes very tedious very quickly.

Men typically start developing facial hair in the later years of puberty or adolescence, between seventeen and twenty years of age, and most do not finish developing a full adult beard until their early twenties or later.
