Got me most of the way

I originally was medium brown, I plan to go to a silver/blue. So I got 2 boxes and got to work. I think it did pretty much what it should have, it got me to a lovely shade of orangutan. lol The amount of dark color that washed out was impressive.
I also have bleach to get me the rest of the way. I would buy it again if I need it, but I have no plans to make such a drastic change again.
