I once had pink hair, it was a lot of work to keep up. A lot of work. It involved bleaching and then coloring with two different types of color and then doing all over again the next week. When I stopped my hair hated me. But occasionally I miss the pink. And when I miss the pink I look for alternatives, I go to convention every year where non standard hair colors are always in style and so when I see something like this, something that can make my hair pink without killing and let my hair go back to brown the next day, you know I want it.
