Daughter dyed hair ~ Help please

My husband and I went on a late honeymoon and left the kids with my mom...  I came back and my daughter went from a brunette, to a beach blonde, to a red head, strawberry blonde, blonde, spotty brunette.  Her scalp burned from what she said by the end of it all .  They had a great time with Grandma but her poor hair  It's been a couple of days and we need to try to get it either one color, even, or back to a brunette.  Can someone help me with the correct way to do this...  Since we just got back funds are low so I am planning to go to Sally's and see what I can do...  She's gotta go back to school tomorrow...  Help please.

We did a scalp repair kit that we were recommended at Sally's yesterday morning.  After I got out of work yesterday I picked her up and took her there to find out what to do.  They said pretty much what you suggested. We went with a medium brown and it came out great (much more even). Her scalp felt okay but she said it almost felt bruised/tender when I touched it when we were doing the other color...  We purchased a really good conditioner (name escapes me) and put that in last night. Her hair looks A LOT better and she's returned to school today.  Crisis averted (for now).
