Hello, I was originally an (artificial) caramel-blonde and decided to go dark; I got it dyed professionally and the colours were as follows: 1/2 4BBC, 1/2 5BGB + 100d (does that mean anything to anyone?). My hair went so dark, almost black but after about 2 washes it went reddish and now has lightened more and still has the red. I am now overseas and can't really afford to go to a salon all the time. I was thinking to perhaps try a dark brown semi-permanent with green undertones to neutralize the red- what level/ colour would anyone recommend I try? I have never dyed my hair myself before so have no idea... I just want a plain dark brown, say Katie Holmes type color...
"green" and "red" mix to become brown, so you need more green to neutralize the red.
Here's a link to some information about base colors
helpful info about bases!!
I'm not sure if you can get the bases you specified.
Your hair is too dark for your complexion. Try a lighter brown -- probably significantly lighter. Katie Holmes' color is too dark for you.
