This is a great example of making a Rainbow Dash cosplay wig by dying one. The cosplayer Kit (Flying-Fox on DA) describes how she dyed the wig and explains that you can vote for her Dash wig! Show some Pony support!
Arda (an awesome wig selling company) is holding a contest for their wigs, and I”d love it if you could spare a moment to vote for my Rainbow Dash wig!

The wig was airbrushed with Liquitex Liquid Acrylics in several stages and coats to prevent the colors of the rainbow from mixing with each other. I wanted to get a nice pastel rainbow effect to the wig, so the main option was to hand dye it myself. The jareth was a great choice for how spiky and full her hair is, and I love the quality of the wig. It styles very easily, and I had to do almost no styling to achieve her “spiky” look here.
