Have: Light Ash Blonde-Want:White Platinum Help?!?

Hey Everyone! This is my first post here =) I'm starting to feel desperate. My hair is a light ashy blonde (achieved with toning), and I want it to be a white platinum

My hair was a dark reddish brown, and after I got it cut into a pixie, I wanted to go platinum blonde. This is what i've done so far:


-Bleached 3 times...once with 30 vol, then 20 the next 2 times.
-Toned with Wella 12A (lightest ash blonde or something) with 20 vol per instruction of Sally lady
-Then toned with Wella T18 White Lady with a 10 vol, per the instruction of a different Sally employee, and this is where i'm at now.

Any help would be greatly appreciated...this haircolour just does NOTHING for my skintone..blegh...it's so ashy

Yes, I totally agree with muppets.  You can also try just plain old real lemon juice.  It is the best natural lighter and toner in the whole world.  It casts out any red, brassy, or yellow tones in your hair.  I would try this method in diluted water every time you wash your hair.
