For an average wig, use 1 1-oz. (29. 6-ml) bottle of ink. For a wig that’s especially long and/or thick, use 2 1-oz. (19. 6-ml) bottles.
You cannot lighten the color of synthetic hair with bleach like you can with human hair.
If you can’t dye the wig outside, opt for a garage or basement instead.
Consider double-bagging the dye to help minimize the chances of spilling.
If you aren’t sure whether or not the wig is completely dry, run your hands through it. If any dye comes off onto your hands, then it needs to stay outside for a while longer.
Don’t use a regular hair brush on your synthetic wig, or you may ruin the wig.
