Need coloring help.

I had long dyed black hair which I've always colored before and never had a problem with it. Recently I tried to lighten the ends of my hair, trying to go with the "ombre" thing- but I used the wrong bleach so it fried my hair.
I had to cut off 5+ inches.

Now the ends are still a little brown because I didn't cut it ALL off (it would have been too short) and my roots are coming in (brown) so my head is a mess.

I want to lighten the  black of my hair to just go with a red but now I'm scared about bleaching it again.  I understand black is a hard color to get rid of. I've had it for 10 years and always colored my hair with no problems but this last time has me a little scared.

If I do bleach it- Could I just put a gentle bleach on there for half of the time just to strip a little of the color out because it doesn't need to be very light for a dark red color.

Is there a bleach you'd recommend?

Oh thanks but I ended up doing it myself.

I put bleach on my hair for a short short short period of time just enough to get most of the black out and colored it red.
Turned out PERFECT.
