Had hair done in a professional salon, it was meant to be a treat as I haven't had it done in years. 
She asked what I had in mind in terms of colour and cut, I showed her a pic of Reese Witherspoon similar to this one I had seen in her hair magazine, long light side fringe, layers, nice natural blonde colour.
Hairdresser did all over foils in an extremely light yellow blonde, then on the leftover hair between the foils she put what she said was a slightly darker blonde but it looked quite brassy/golden orangey colour. She then chopped in an extremely big blunt fringe, which, as the whole fringe had been bleached, isn't even heavy enough to sit nicely, it just sticks out like nasty old barbie hair. Like this
I wasn't entirely happy with the look in the salon but I'd been there for hours, I had an appointment to go to, plus the hairdresser was all "you look SO good! SO much better" - anyway I got home and just felt so disappointed and ridiculous. My skin looked red, blotchy and unpleasant next to this totally false, flashy colour.
So I grabbed a box of ash blonde colourant I already had in the house to attempt to tone it down. I literally painted it on, then washed it straight off, as I just wanted a tint, not a full colour. Thank god I did because even after less than 5 min on my head, my hair still turned faintly green/grey. Having googled since, I see that adding ash to bleached hair is a big no-no.
I tried putting ketchup on for 30 min, it made no visible difference. I haven't done anything more to it, I'm wondering what's best to do. I could buy colour b4 remover, to strip out the ash, or I could do a bleach shampoo thing I read about, or I could add a semi permanent golden blonde colour to try and cancel out the ash. Having it professionally done is not an option, I've shelled out £60 for them to wreck my hair, not trusting them again, or wasting any more money on that kind of thing! Any advice please?
