haha I actually dyed my hair bright red once, the colour only stayed nice for a few days and then steadily turned more and more orange. Red fades so fast, but it looks freaking awesome when it's fresh. Post-bleach hair isn't very happy though =(
Deep conditioner works wonders for damaged hair. Trust me. Try mixing some dye with your shampoo and condition her. Makes it last a little longer. That's what I did :)
