Thanks...it took a bit of time because I initally left a lot more blonde parts and then decided it looked strange (kind of like my hair couldn't decide which color it wanted to be!). I then added more brown and then a bit more to even it up.
All in all, I think it took me close to 1.5 hrs or so, including the bleaching. I used a whole container of hair color (even on my short hair) because I kept having to reapply it. I like it, although after straight blonde it took some getting used to. I think next time I need to retouch, I'm getting a darker brown and trying to add the red.
I've read elsewhere that the Clairol Intensifier turns out a bit pink when used on bleached hair, so I'm not sure if I'm going to try to use it, or if I will just return it to Sally's and purchase a red SFX or some other veggie dye. I think Blood Red would work if the brown was dark enough. I'm not really wanting pink, though. I want a true red, which of couse has to work with the brown color.
Next time, I'll be going darker and more neutral. Over the already blonde hair, this brown is really golden. It's not bad, but usually I lean toward the ashier shades.
