Why do men shave and comb their hair?
Fair question.
I shave about once a week - when I do it’s because I realize I’ve become unfriendly-looking.
It’s like the lady said upthread - a little grooming is a smile to the world.
Actually, since I retired that burden removed has been the source of immense pleasure and satisfaction. Combing hair? I just take a Wahl hair trimmer with a 1/8” standoff and buzz it off once a week. No huhu, no problem.
I don't shave nor comb my hair. My hair is too short to comb, but it does take a good 8-10 to was my mustache just right. (and if I don't I will be straining everything I drink) Women love my handlebar mustache and frequently let me know. Trim and weed the beard weekly.
