I was slightly nervous using permanent hair dye at home as I have only ever used temporary (24 wash) hair color at at home. However, this was really easy to apply, no mess no fuss. The instructions were crystal clear which left no room for disaster, and the application itself was mess free as well. The hair dye had quite a pungent smell, but I think that is standard in any permanent hair color. I left the color on for the required time, and during this time the color stayed put and I didn't have any tingling sensation on my scalp or anything like that. I washed my hair per the instructions and have been pleasantly surpised by the results. First off my hair has a lovely fresh fruity smell. The color itself is vibrant with a nice shimmer, but hasn't altered my own natural color so much that it looks false (I am a natural brunette). I like the reddish tinge to my hair and best of all my hair feels and looks healthy! I will definitely be making use of this product again :)
