How do you dye synthetic hair?

[Ginsana]

I'm trying to dye my phony ponies and my falls to match my new highlights, but much to my dismay, they aren't taking the color. Any ideas on what I should do because I can't seem to find any phony ponies that are already made to match my new color...

Synthetic hair can't be dyed. You'll need to buy a pony made from human hair.

Actually, contrary to popular belief, synthetic hair can be dyed - just not with regular hair dye and it can't be dyed lighter (from a darker color). You have to use a fabric dye for synthetic hair "a liquid fabric dye, such as Rit or Tintex, may be used to darken the color on synthetic wigs." - Problem is can you find a fabric dye the color you need...
