By savagely battering the inferior DNA-haver in bareknuckle combat and then using your position of dominance to loom theateningly above his shattered body and loudly mock him for his male pattern baldness.
Shave it off, pussy. Being bald is way better than being the guy who desperately has to comb-over the remnants of his hair or is spending hundreds a month on snakeoil.
Shaving it off seems to work well, but I miss the style where men would just shrug and keep it short. That "hair's gonna hair" attitude. Look at most US Presidents after the wig era: keeping it clean and neat, worrying about other things.
