I kinda wish they’d had that stuff when I was young enough to wear it and get away with it!

Temporary over-dyes turned up when I was in college, so that would be the late 80’s. I bleached mine with hydrogen peroxide when I was in high school. It ended up glowing orange and took forever to grow out!
I’m glad Anoreth can mess with her hair with less risk of a major disaster.
