I mean... you can have your male sim wear womens hair...so men still got new hair today technically, its not the only spot in the game with differences between sexes.
I have two sims (1 male, 1 female) they both have the same job, go at the exact same time and both work hard the entire time, the male sim has gotten promoted a day or two before the female and another time they gave both sims a promotion but only the man got the bonus. I thought about making an entire thread about it but was unsure how it would go....
