Michelle, I have used sharpies before. The SAT test just isn't the SAT test without sharpies and severe hair damage.
I've been thinking about purple. I might rule out red, because last year I did that, and my hair turned orange after a few weeks of chorine exposure. I looked like Ariel the Little Mermaid after being dunked in bleach. xDD
I definitely want a little black, and another color. Plus, that was when my hair was un-straightened, which it usually is.
And Esther, yeah, my hair is getting lighter and lighter. Pretty soon I'll be really bleachy, if that's even a word, because of the harsh summer sun. It's the circle of life 'round here.
And so I still don't know.
