How long does kool aid take to come out of your hair?

The way I did mine(I did red) was, I took it straight out of bottle I mixed it in to drink, and I heated it up on the stove. I dipped my hair into it, and did it until it was even. It took ten minutes. My friend had to help me, but it shouldn't take too long. I did it in late December, and right now it is a faded red. It's early June now, and the color has not turned a weird shade of orange.
