Bleached my hair, now gingery with yellow roots - advice please?

[BreadAndJamForFrances]

Hi, everyone, I hope you can give me some advice. I had waist length wavy natural blonde, but in my late teens my hair began going to a darker blonde/mousy colour. I started colouring it with Nice and Easy Natural Baby Blonde (to match my natural colour) however, around 7 years ago I got bored with bleaching and decided to go dark and get it cut.
I had a mid brown with purple streaks and shoulder length cut done at the hair dressers, but it cost me a fortune and the colour wasn't really as bold as I wanted. I went back a few more times, and then decided to start home dyeing to get a stronger colour. I also had it cut to a chin length bob type style.
For the last few years I've been using Live Colour Mystic Violet or Cyber Purple. Now at 36 I have some greys and I don't think the dark hair really suits my skin tone any more, plus my mousey/grey roots look really awful against the dark dyes. I've grown it halfway down my back again which I love (and strangely it has got really, really curly as I've got older, which I also love!!)
Six weeks ago, I had an event to go to, awful roots but didn't want more purple, so coloured with a semi-permanent chocolate brown to cheer it up. It was a very boring colour, still too dark, but at least one colour all over, more or less! This has given me the push to go back to baby blonde....I've been dithering for 18 months!
So, two weeks ago I bleached it with a fairly gentle box bleach to see what would happen if I went down a couple of shades.....nothing much is the answer.....the roots lightened a little, but the ends didn't really change. So, this week I used Colour B4, which was brilliant, took away all the dark dye very effectively. I followed this the next day with Nice and Easy Baby Blonde......which has had the desired effect on my roots, but has left the rest of my hair a rather lovely gingery auburn colour! It looks kind of like a dip dye technique. Now, I want to get it all blonde, preferably in time for Christmas, and preferably all the same colour. I have one box of baby blonde left, (very thick, long hair took three boxes) Would it work to use this to bleach bath? or does that only work with powder bleach? Should I cover the lot with a light brown and leave bleach til next month? Or is there some way I can be blonde for Christmas? (My hair was in great condition before I started, still feels great, but very slightly drier than before, I use The Body Shop Rain Forest shampoo and conditioner with no silicones)
Thanks in advance :)

Hmm, I'd be wary of doing anything else to it at home with the amount of chemicals it's had on it recently. There is the danger that it will damage it to the point of breaking off! As pricey as it may be, I would go to a hairdresser and ask them to sort it out because you don't want awful colour in your Xmas photos. Yes it will involve chemicals but they (hopefully) know what they're doing so won't bugger your hair up.

Whatever you do DON'T TRY AND DYE IT BACK DARK to hide what's happened. I had much the same as your experience a while ago and by doing this ended up with delightful browny green hair. It was awful.

Ash blonde is your friend. Anything with ash in the name. It will state on the box that it will cover coppery tones etc.

In a couple of weeks, the ash will fade and some of the bleach will come through and it'll be lighter.

If you really want blonde hair, you need bleach. I've painted it on the past, let it develop, washed it out and then used a loreal preference colour (which is good because you can put it on wet hair). Not good for your hair, and a ball ache, but you will be blonde.

Get to the hairdresser. This will only end in disaster if you keep trying home dyes on fairly monumental shade changed.

You might be able to maintain it with packet dyes but it needs to be done properly the first time.

Thanks for all the replies.....I really don't want to go to the hairdresser....I live out in the sticks, so there is not much choice and it would be an all day thing, which I have not got time for.
RabbitRabbit78 - I won't put a brown over it then, don't fancy going green!

HowAboutNo - I don't mind being ash blonde for a few weeks, then I could let my hair rest and colour over with my desired baby blonde.
Do I need the lightest possible ash? Like this for example, or would a darker ash be better? And, I do need to put the ash on the roots too, don't I? Thanks for your help! (I'll live dangerously and dye it before Christmas, if the worst happens I'll get a pixie crop!....my hair grows really quickly, so won't be for long, lol)
