But in the photo, her hair was a boring brown colour instead.
Her headmaster at Northgate High School, Mr Watts, had decided that pink just wasn't right for a year group photo, and ordered the photographer to change the colour.
A big stink about the pink
Mr Watts said he allowed Ashley to stay at school because she was in the final year of her GCSEs, but had asked her more than once to change her hair.
She didn't, so the pink got the chop perhaps to deter other pupils expressing themselves with unusual hairstyles.
Ashley has complained about the swap, saying that no one from the school told her about it.
