Probably my favourite dye so far. It's really bright and it works on undyed hair aswell! But now that I've done it on almost white hair, it's just stunning. And I didn't notice any powder, nor has it stained any of my bedding or clothes except for the hair towel, cause it does bleed a bit for the first few washes, but I just blowdry the hair, to prevent staining clothes. Staying power is 4 to 5 weeks, which for me is great! -ASG-
