Not too long ago, around the 80'-90', having a long beard, even a short one, seemed to indicate you were financially and even socially lacking.
But that notion has significantly changed in recent years, according to research by Neave and Shields (2008) on the effects of facial hair on women's perceptions of men's attractiveness, masculinity, and dominance; and also according to research by Dixson and Brooks (2013) which used similar procedures and recorded judgments by both men and women on the faces of men with varying degrees of facial hair.
Well, unfortunately, the overwhelming majority of men worldwide are simply unaware of the importance and I daresay power of a good outfit. Most of them say they don’t care about fashion. Some will, however, admit that they do understand the advantages of looking good (i.e. The Beauty Premium) but they simply don’t know how and what they can\need\should do about it.
This is the very heart of the answer to this question as it leads to the fact that most men shop (if they shop for themselves at all, that is) with little or no sartorial knowledge or understanding.
Statistics show that by the age of 35, around 66 percent of men lose a considerable amount of hair, and by 55, 85 percent of men have significant hair loss...by which I mean bald or balding. I'm really sorry, but that means there's a giant chance you're either going to go completely bald, or at least partially.
Let's be clear: There’s no shame in hair loss. A lot of us choose to embrace it, rather than trying to regrow it. Even if you do take the measures to grow it back, it’s unlikely you’ll ever have your 18-year-old hairline again.
