It is possible for a guy to look to two girls as equally important to him in reference to what they do for him individually.
One girl is game to do any activity he is into, including guy-centric activities such as playing sports with him, which makes her a girl that is like one of the boys.
The other girl is quintessentially feminine, looks really pretty on his arm at a social event, and boosts his social credentials as a result.
Dark hair is a plus, but it isn’t all that much of a factor, should any one of the prior factors be missing.
Assuming the three extremes where she has to pick between a short guy with a handsome face, a tall guy who doesn’t have a handsome face, or a guy that is neither tall nor handsome, but has dark hair, she is choosing the short guy with the handsome face.
Women don’t want to have to choose a guy based on these extremes.
