I was attempting to cover up henna that I was fed up of waiting to grow out. I also had about an inch of dark roots with scattered grey to cover as well so the dye had a lot of work to do. I left the dye on for about an hour and was pleasantly surprised by the results. I mixed this dye with the Cyclamen pink and the roots came out a pinky-purple colour while the ends are a, lovely dark red. The clean up was kind of a nightmare as it stains instantly and is hard to remove which is a draw back, but I do love the result so I would definitely use it again.
