Heritability of facial hair growth https://www.ancestry.com/lp/traits/facial-hair-thickness
The inborn traits that us men preoccupy ourselves with (Height, muscular density, IQ, penis size, vocal chords) are largely determined by genetics.
Yes, there are processes we can undertake to enhance our attributes, but only within their predefined limits.
If we all possessed the ability to significantly increase our attributes through our own doing, every man on earth would be walking around as a 6ft 3 Adonis God, with bulging 6 pack muscles, an IQ level matching Einstein’s, a 10 inch penis slapping against the side of our knees, a deep baritone Johnny Cash voice and a thick Vikings beard. But that’s not the case, human beings differ across many domains and what one lacks, the other excels in.
Life is much like an MMORPG (Massively multiplayer online role playing game) like “The World Of Warcraft”. We would aim give you a haircut befitting to your facial shape and structure in an attempt to mask your deficits and increase your attributes. It’s the same with genetics, play your strengths and minimize your deficits, in order to live the best life you possibly can. Let’s be completely transparent, if you’re incapable of growing ANY facial hair, at the age of 40, you’re probably out of the game (unless you decide to get a beard transplant).
If you can grow sparse facial hair, there may potentially be a glimmer of hope. As men age, their physical frame widens out. As they age, their facial hair typically grows thicker.

Nevertheless, if we’re aware of the fact that life itself imposes her limitations of nature upon us, why not do our best to maximize what we can within our limits? In other words, although genetics prove to be a dominant influencing factor in regards to beard growth, thickness, and volume, we can enhance what we’re born with and make the best of what we have (If you have anything in the first place).
Now that the depressing news is out of the way, lets proceed with the optimistic endeavors we can undertake to influence beard growth.
