Best Answer: The directions say to leave the color in for  30 minutes if you want it to last for six months. That refers to the color, NOT the bleach! I myself left the color in for an hour, but the life of the color really just depends your shampooing habits. Also, for Pete's sake, don't let any of the dye get on anything but your hair, as Splat tends to stain unforgivably.
So, I recently dyed my hair an unnatural color for the first time (picture is attached), and I'm extremely happy with it, but people are constantly giving me crap about leaving the dye (not the bleach) on for a long time, about 5/6 hours, saying that all my hair is going to fall out or I'm going to get dye poisoning or something.
