I do recall it was pretty close to what you have suggested though~ one part bleach mixture (I used 30 vol developer), 1 part shampoo... Can't recall adding water in it, but not positive about that one..

 

I'm not sure if you've thought about/discussed this topic yet as I haven't been on the colour forum for awhile, but have you considered Color Fix?  It is 'supposed' to be gentler than bleach and can really take colour out of your hair well.  When I needed to get some awful brown and red colours out of my usually level 9/10 blonde hair,  I used Color Fix to get what I could out and then used a bleach cap to lighten up from there.... Then we toned it with a 'gentle' toner (that used a small amount of peroxide in it) and it was much better!

 

Good luck~ Hope it turns out great! 

 

Sorry I have taken so long responding... I didn't realize you had posted a response

 

Yes~ I used the colour fix (the half remover or the gentler directions that they include).  After that, I used the bleach cap which brought my hair right back to a level 9~ although it was a 'mucky', dull level 9. 

 

At that point, I went into a salon and had them do what they referred to as a 'flash toner'~ which was basically just a toner that used approx 7 to 9 vol developer. 

 

I only used each method mentioned above once...and didn't do any on the same day.  One thing I've noticed since getting my 'blonde' back is that whenever I go in to the salon to get my roots touched up (every three to four weeks or so), we have had to tone it more often that we used to before the 'colour disaster'!  Before, it was toned maybe once every fourth visit and now it is almost every other visit~ sometimes a couple salon visits in a row. 

 

If I lived in the USA, instead of going to the salon for the 'flash toner', I may have also just gone to Sally Beauty and purchased Clairol Born Blonde toner in a shade like 'Silent Snow' or similar... although I colour my hair pretty light with ash tones.  You could go with whichever suits you best.  Or try the salon too.  It is often worth it if you trust the person colouring you... I'm just so fed up with salons because the two hair disasters I have had in two years were caused at high end salons with good repuatations, so I am a bit nervous and now watch everything they do and repeat myself over and over to ensure so mis-communication.

 

Good luck!  PM me if you need help, I'd be happy to pass on any info I can~I'm not a colourist or hair stylist though, so others on here might be able to help more.  Also, don't forget to give your hair lots of TLC with deep conditioning (wrap hair with a hot, damp towel or sit under a hair dryer while deep conditioning), etc... to help with the damage it can get from all the colourings!
