I think girls with Blonde hair can be very beautiful. Some girls with Brunette hair can be equal on terms of looks with Blondes. But I prefer Blonds because combined with blue or green eyes, they are stunning. But any eyes color will match the hair color and skin tone. They are my fantasy and I dream of marring a Blonde. When comes to being smart, everyone is the same it just comes down to who study's more and on what. But yes I would pick a Blonde over a Brunette when comes down to dating and more.
Come on already. Every person has his/her own opinion and one color might look fantastic on one girl and bad on another. Just make your hair whatever color makes YOU feel happiest about yourself. It's your hair so make it how you like it.
