I saw this article on my local news station and I was very surprised they thought her hair was unnaturally colored. Its red. In fact I think its beautiful on her. I think the school is in the wrong here.
What some people need to understand about the school though is that the town is small, very judgmental, and super conservative. They are not open to new ideas and they have a mentality that I cant even explain. I am not speaking from experience as I have not lived there, however I had a best friend in high school that moved from there to CA and her family left because the people were all very harsh and judgmental. My friend got suspended because her shorts were too short. Her shorts were almost to her knees, but the principal wanted shorts to be at the knees. There was no school policy about shorts when she got suspended. Her family fought it but lost because the town sided with the principal who they knew and not these "outsiders". Very sad if you ask me.
