As a student, the most important and the only request of my hair style is convenience.
I don't want to spend too much time on taking care of my hair, so i would like it to be short and clean.
In that way, after i do some sports, it will get dry quickly, to help me being away from a cold, and also to help me build an impression of a healthy boy and a boy full of passion.
A good hair style can help to give more confidence, but it should be acting like a bonus instead of a main factor of your life. All in all, the inner side of a person is the most important side.
