I have noticed a rise in people wanting to go white blond all over, I have used blondor with 9% and when rinsed off I am left with a light but luminos yellow tone, I have then applied a color fresh 0/6 (violet) toner but I am not happy with the result as it hardly makes a difference, I know that violet is said to tone down yellow tones. If anyone has done this white blond all over look could you let me know how you achieved it. Many thanks.

What you could have done was leave the bleach on a little longer, it would have stripped out the yelloe and left you with the white sort of blonde hair you wanted.
You could reapply the bleach and remember to regularly check it as I am sure it will not take long for the bleach to strip out the yellow tone. Don't leave it on too long as it will leave your hair completely white.

Hope that helps.

PunkChic is correct. If your hair is too yellow, the violet won't counteract the yellow. You should re-bleach to the pale yellow stage. It's said that pale yellow is the color of the inside of a banana peel. That's probably the color of the banana meat, itself.
