someone is just jealous of blondes, I get the feeling you hate blondes and want everyone to say she should go brunette obviously. that's stupid because the biggest determining factor on what hair color will look good is the face!
maybe her face goes better with brown hair than this color, who knows. but from what I do see the blond hair looks extremely hot on her and suits her well. many people on here hate blond hair from what I see but in real life it is really sexy and lots of guys love it. yes even if it is highlighted or dyed if the girl can pull it off right.
and to be honest a lot of girls do look hotter blond, IF it goes on the girl's face and coloring! so really this is kind of a dumb and pointless question!
blonde and brunette are both sexy! some girls look better blond, some girls look better brunette, some can pull off both, but what makes or breaks it is the face!
in general I do NOT think she would look better brunette cause blond hair is hot in general. however, IF I saw her face and it looked bad with blond hair then I would change my mind!
so based on what I see, NO she would not look better with darker hair.
