I'm a dark brunette and have had greys coming through for years which I dye to cover. I've always used Garnier Nutrisse Dark Brown but there's a red shine when it's first done and then it fades to orange, which just looks awful on me. I'm fed up with it so I did some research and it was suggested that an ash colour would stop that red shine/orange fade. So I've just used a Clairol Nice and Easy Ash Dark Brown but low and behold there is a red shine!!!! Which means that this too will probably fade to orange in 2-3 weeks. Is there a dark brown dye that is just...well...brown?? I really can't afford the cost of a hairdressers trip, upkeep etc so it really needs to be a box dye. Am I looking for the impossible??
