I used the semi-permanent lilac colour. I had dark brown hair and bleached half of my head and dyed it after. The colour took really well to the sections that bleached the lightest, such as the roots, whereas the sections that were more yellow had turned a weird green colour. Overall I wouldn't expect a very purple shade, it's more of a blue lilac, but still very pretty where it dyed properly. Would recommend dying your hair if all of the section is the same colour, and make note that lighter hair will get the best results. Overall though, it's a great dye! Great vivid colour. Just don't make the mistake I did, and make sure your bleached hair is all one colour for even results.
