Special Effects Blue Velvet Hair Dye

The best blue dye I've found so far! It works fantastically over dark unbleached hair, and gives a very strong, vibrant sheen under most lights instead of the occasional hint you get with most blue dyes without bleaching. The colour does change from black to blue to plummy purple depending on light and how much it's faded, but as long as you don't over-wash it (dry shampoo is a lifesaver!) it lasts for a very long time and doesn't go green.
