Cosmic Blue Disaster

Hello everyone, I've had a small disaster with a hair dye and would like a little advice, if anyone can help me, brilliant!! First a little background about my hair colouring history.

My hair is naturally very dark almost black, years ago a hairdresser told me I had a lot of natural red in my hair and so I started getting reddish lowlights to enhace it. I fell out with this hairdresser after one of his juniors made a mess of colouring once and never went back.

So for about 7 years now I've been using various home colourants but always roughly in the same reddish tint, I loved the L'Oreal colour booster but I felt it made me look too pale and washed out so extreme was the red however it lasted forever and looked great when I used straighteners (which isn't too often) the last product I used was Schwarzkopf Live dark, dark red which faded too quickly for a permanent and with around 10% grey the grey strands look orange.

I yearned for my old natural nearly black for some reason, maybe the change and faced with two choices, Cosmic Blue which doesn't really look that blue on the packet and another plainer black what did I pick???

You guessed it, cosmic blue. Why??? I'll never know but I looked like an aging goth LOL I'm 38 and it's not cool looking. I've just done it this evening but shampooed my hair twice which has gotten rid of a lot of the blue tinge but I'm still not happy.

It doesn't match my black eyebrows so my question is this. If you were in my shoes would you go out and get a more natural black (but not Schwarzkopf Live) to see if that will help or would you just shampoo it like mad and hope it fades as quick as the dark red did and then go for a dark, dark brown or even back to the reddish tint???

Anybody else ever used this horrible shade of black??

I've been reading some of the black hair disaster stories and I feel for you all, however since my natural colour is almost black it's easier for me to deal with although still a shock to the system, I can't imagine what it would feel like for someone with light brown or blonde hair to realise too late they'd made a mistake.

Thanks Katherine, I can live with that but I'd love to have a red hint even a very small one just so when the light hits it, it's there.

Can I get a semi permanent in say 4 or 5 weeks for the red hint???

I hope I didn't offend anybody saying the blue/black is horrible, I meant really that it's horrible on me but for someone younger it would be nice.
