Most Helpful Girl
I'm a girl and my hair is short right now. I know 100% that it will never be as attractive as long hair to guys. Very few girls can make short hair look good. When a girl cuts her hair short she is most likely going through some depression, needs a change in her life.
Or really sometimes the girl has damaged hair from overdying it and just wants new fresh healthy hair. But that's probably like 20% of the case. For the other 20%, girls cut their hair short just because they want to see what they would look like, maybe their friends are doing it too, maybe they look up to a celebrity with short hair.
