I have never personally tried it.

I thought about trying it but a lot of people I talked to told me it was very damaging and didn't work as it should.

I have had a few dying disasters so I have a little advice. lol.

If you just dyed your hair, don't worry. Red fades really quickly and at the end of two weeks it should be a lot less red.
When I dyed my hair too red I shampooed twice a day for a week and a half with sulfate shampoos to fade the color. (Purell, Head and Shoulders or Pert work well for this).
If you do this remember to deep condition!!!!

Basically, my hair turned to a reddish brown which I actually liked.

If it terrible beyond repair go to a salon and they should be able to fix it. I would not trust color oops.

Good luck.
