Special Effects hair dye!!!!!!!!(only if you've used it)?

My friend used that before, the deep purple stuff. I was there with her when she died it. Her hair was dyed blond but not bleached. We had to dye it 3 times, leaving the dye in for about 30 minutes each time, because it didn't very good. But after the 3rd dye it looked pretty good, and really purple. It lasted for about 2weeks-ish.
