In my old school, only natural colours were allowed. And you weren't allowed to shave your head and have patterns in it either.

I think the idea with uniform and appearance in schools is that they want the community to see the school in a positive way. Also, it's like preparation for the world of work as you may have to wear a uniform and look presentable. That said, everyone makes the argument that having different coloured hair doesn't affect your learning, which I agree with
