I have dyed foe before! It was for personal use though! I had dyed foe with rit dye to match my daughters pageant dress (she didn't have enough hair to really clip her bow in so I made a foe band) it turned out good! Just make sure your using the right amount of dye! I didn't use enough my first time and it turned this vintage blue jean color, and the 2nd time I. Added to much and it turned black lol...the 3rd time I got it just right and it was royal blue!
