hello!! i want to cosplay muichirou tokitou from kimetsu no yaiba, but i'm having trouble with his hair. he has mostly black hair but it's a light blue/teal at the bottom, and it doesn't seem possible to dye a black synthetic wig to a lighter color. would i have to start with a white/blonde wig and dye the whole thing from scratch, or is it possible to do it another way? thank you in advance!
I can see two ways of going about this.
One would be to get a black wig and add the blue wefts to the underside, making sure to trim the black hair in a way that allows the blue hair to show in a gradient like the reference. This would be the easiest way to do it if you don’t want to deal with dyes and would create a very clean-looking effect, but wouldn’t be 100% accurate because of the layering required.
The other would be to dye the wig by hand. You would start with a blue wig and then either dip dye it to get the black on the top or you would hand color it with alcohol ink or alcohol-based markers. Dip dye would be a more stable way of dyeing the wig and could potentially produce a darker/truer black, but would potentially be difficult to control, and you may run into issues with the amount of heat and time that dyeing wigs with polyester-safe fabric dye requires. Hand coloring the wig has the possibility of the dye rubbing off or staining, especially if you use any sort of styling products on the wig after, but would allow you to have more control over where the color goes.
If you do the dye method, be sure to get a wig that can handle whatever dye method you choose, as some fibers don’t accept some types of dye, and you don’t want to accidentally frizz your wig by sticking it in dye that is hotter than the fibers can take.
I hope that helps! Good luck :]
