I do not believe that any hairstyle is cultural appropriation, with that being said, whites habe set the standards of what dress, hair length, and facial hair are appropriate or acceptable for beauty, for events, for society, and most importantly in school and the work place. So the very idea of cultural appropriation in regards to caucasians is beyond silly. That was strictly enforced assimilation and non conformity always effects the way one is treated by many, not all of course.
