HELP.... dying my hair back to blonde, but i have fusion extensions!?

My natural hair color is a medium blonde. I went from a platinum blonde to a dark brown about 6months ago. Yesterday i decided to go back to blonde... I used blondissima highlight bleach to strip the color... but what i ended up with was about 2ins of yellow at my roots and the rest of my hair was an orange brown.

SO i then decided to add Loreal Excellence Ultra Ash blonde to my hair and although it made it light, i STILL have the 2 tonal look going on.

I want my hair back to a nice ash blonde rather than this horrible brassy yellow/orangebrown.

ALSO i should add that i have 18" fusion extensions that i put on AFTER all the dying, but need to know also if i can go ahead and dye the fusion area.

(tried the purple shampoo...it was wonderful, removed the yellow, but the extensions are now a purplish color... HELP!!

1) how do i make my hair look ashy rather than coppery?

2) Can i dye near my fusions?

3) Will the purple shampoo color wash out when i shampoo?
