Throughout school, only natural colours were allowed at my school. You weren't allowed to bleach your hair or even go from brown to blonde or blonde to red. You also couldn't have coloured hair ties (only blue or black and they couldn't be wider than two and a half centimetres. We also weren't allowed to have our heads shaved or have any funky hairstyles.

But at my brother's school, they're allowed to dye their hair for spirit days providing it is gone before the next day.
