Can I apply minoxidil rogaine 2℅ lotion on my upper lip scar region? Is it helpful in bringing my moustache back?

The application of minoxidil may not be useful in the scar region as there may not be any hair in the underlying tissue. So, the better option would be to get a transplant done in this area.

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. The drug minoxidil may help.  Beard transplants can be done when the young man is a bit older (over 25) if the beard has not grown in yet
