Because generally guys don’t care as much, marketing works in a way of supply and demand, so women buy make up and more people make more make up and put more ads everywhere of pretty women wearing make up and it creates a cycle of buying and selling and there’s a demand so they make more and that means more ads and more women are more pressured to wear make up and what not (same goes for all beauty/looks things) where men don’t really care about that stuff as much only as much as they need (the vast majority say like 90% of men the other 10% are into that stuff) so there is just less stuff about men’s appearance all over the place and it’s talked about less in magazines and all that it’s just how it is. Men are pressured to know how to do things like use tools and fix things or be strong or what not because that is what men care about (in general Not all men are the same)
