HELP! Will Colour B4 work in this situation- or will it make my hair ginger?

[jumpinghoops]

Hi all-

I have had hairdresser highlights for years and years, then dyed it with Nice N Easy medium golden blonde which was OK and prob quite similar to natural colour.

However- BIG MISTAKE- thought I'd try John Frieda Dark Golden Blonde and I am now sitting here with very dark reddish roots and patchy blondish reddish throughout the rest. I always apply really carefully but I guess it's taken in bit of my hair rather than others. I am the first to admit I don't really know what I'd doing and should prob leave to the professionals.

If I use Colour B4 will it make it lighter version of what I have now (ie. ginger) or will it totally strip all of the reddish colour out of my hair?

Thanks for any advice- can't go to work looking like this so need to try and do something emergency over the weekend!!

Well I have found it to leave my hair ginger.
One possible option is to pop an ash blonde over it to counter the red. You can do this with a semi p.
Second- try touch of silver if it's not too red. It's a vivid violet shampoo and does knock brassy tones into touch if your hair is blonde/ light.
