Beard growth - any hormone injection available? Any side effects?

There is no hormone available to stimulate beard hair growth. PRP could be injected to stimulate facial hair thickness and density.

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 (either side of the family) started to grow their beards. Hormones should have kicked in nicely by the time a man reaches 18 but some people must wait out his genetics as hormones alone are not responsible for the onset of beard growth. Beard transplants can be done when the young man is a bit older (over 25) if the beard has not fully grown in yet. Minoxidil may help and if it works, then you are among the lucky few. It often produces very fine hair (called vellus hair).
