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.
How soon after you dye your hair can you dye it again? Whenever I bleach my hair (to get my roots) the dye comes out kinda light, the 2nd time I dye it I get the color I wanted. I usually wait around 1 week to 1 month before I put the 2nd coat of dye on. The question I'm trying to get at is; how soon after dyeing my hair can I dye it again, without causing any traumatic frying of the hair? If it plays any significance, I use Special Effects.
