My goodness I find school hair codes to be the dumbest thing ever. How can styling one's hair affect your learning? It can't! This was a huge issue at my school and I found it absurd when the school cared more about our uniforms and hair rather than the terrible quality of education that we were getting. I know there's an independent school in New South Wales (always in the top 20) who don't care how short the skirts are or what hair colour the student chooses. The fact that students at that school are free whatever they want, comes to show that "proper" uniform/hair style and colour does not necessarily equal a great education. Why should the school dictate how you should present yourself? The rules for uniforms are already enough.
just a small rant about an incident that happened in 2017
I still remember this incident from the first day of school last year. I was sitting in the office at first aid, minding my own business, when out of nowhere an Asian student (yes, her race is relevant to the story) and the assistant principal are arguing. The reason why? The Asian student had dyed her hair blonde over the summer holidays. In our school diary, it states that natural hair dyes are fine. The assistant principal still insisted that she should dye her hair back to black because blonde wasn't a natural hair colour for Asians. I find this very hypocritical because I remember seeing girls in my homeroom later on that day, who've either dyed their blonde hair into brown and vice versa. They never got into trouble. Why? Because they were Caucasian. I'm still quite annoyed about this incident and the assistant principal never got investigated for this. It was racially motivated to specifically target the Asian student alone. Pathetic.
Honestly, as long as you've managed to comb your hair before school, do whatever you want with your hair. Dye it green. There shouldn't be any form of punishment at all for simply dyeing your hair or even having it down (huge problem within all girls schools).
