I am 21; I have a moustache but not a beard. Sometimes I'll find 1 or 2 hairs on beard. How can I grow a beard faster? (Photo)

Beard hair is a genetic trait. If you are past your puberty years with no facial hair then there isn't much you can do to grow facial hair.  A surgical option would be a beard hair transplant.

Many young men want to accelerate their beard growth and ask about it. It takes age (genetic triggers which occur in family lines) so if you want to find out when your beard will grow out, you need to find out when your father or grandfather started to grow their beard. Hormones should have kicked in nicely by the time a man reaches 18 but he must wait out his genetics as hormone alone are not responsible for the onset of beard grown. Beard transplants can be done when the young man is a bit older (over 25) if the beard has not grown in yet
