hair color and a shower cap

i just discovered the solution that probably a zillion people already know about... when you use at-home hair color, take your dye-drenched hair and put it a disposable Shower Cap! they are like 3 for $2 at wal-mart. no more worries about drips on the floor etc... plus the shower cap holds in the heat from your scalp, which helps to slightly accelerate the coloring process.
