Good dye, it didn't cause any irritation for me (something very important for me since I couldn't find a dye that didn't cause irritation and itching). It's been a month since I dyed my hair, it's still dark but not black-blue like I dyed it. It fades with every wash, but maybe it's because I had bleach underneath. I have ordered it again now to dye my hair again in a month because my hairdresser told me that it might penetrate more and not fade so easily. I am generally satisfied, I just wish the color lasted longer.
