I am 24 Years old male and I cannot grow beard. A subtle mustache & chin beard is what I got, but I don't have a fully grown beard. There are thin hairs present on my cheeks but they do not grow to its full capacity & thus, cannot be considered a beard. I have hairs fully grown on my legs, armpits, genitals, however only my facial hairs are absent. So it would be of great help if you could help me out in this regard to grow beard at its full capacity.
