I have a small scar on the center of my upper lip which is fairly visible when i'm shaven, so I thought id go for a stylish moustache in order to cover it. Problem is, Iv'e read that hair won't grow on scars and im afraid it will still be visible.. altough iv'e seen 1-2 hairs grow from that one spot so i'm a bit confused. Basically, I wonder if theres any methods in speeding up the moustache growth? Or force hairgrowth around/on the small scar?
