Can you dye chemically straightened hair?

my friend chemically straightened her hair...yes I know shes a fool for this. she later on after letting it sit for 6 months got extensions. they fell out, later she tried dying her hair black because of its colour fading, so when she did...out of no where it turned orange and died. We have used every great brand on her hair, elements, beyond the zone! everything! nothing has worked. suggestions? >_<

Hi,

Just stop. Stop messing with her hair! You're killing it with all this stuff. Go to a salon and talk to someone who knows what they're doing, and who went to school for it!
