Not really .
dye your hair
Just 'cause.
no it won't if you dye it then it won't wash out. permanet dye will work the most.
It does work but it really depends on what kind of hair you have and how well it reacts/absorbs the bleach and dye.
yes...
Yes, hair bleach might work and normal bleach might work. Hair dye is a stain, so it's not permanent.
It might work better if you use a color stripper first to get the green out.
hair dye
No, I am pretty sure the dye would not work if the wig had arteficial hair. You could just buy a new wig?
You can dye it with that hair dye it won't go bright red but will probably be very red
redhair dye.
A darker brown hair dye does not work on blue hair, and using it leaves your hair vulnerable to discoloration by sea water or chlorine.
