How Do I Get Red Out Of My Hair?

I've been dying my hair for 10 years now. I've colored my blonde hair red before and always used those hair removers to remove the red later, but they are so harsh on your hair, and it always turned my hair yellow or orange which i then had to recolor. I just colored my hair red again 2 months ago, and a few weeks ago i found a posting to get red out.All you do is use 1 part vitamin c and 2 part pert plus shampoo. I had those emergen-C vitamin C drink mixes you're supposed to take when you are sick. I just mixed two packets of that and some pert plus shampoo. You can also grind up 2 tablets of vitamin c. Put it on dry hair and let it sit for 45-60 minutes, then rinse out and condition your hair. You can keep repeating this too if you need to. I didn't think it would work but it truly does!!!! I just wish i knew about it sooner so i wouldn't have spent so much money on hair removers and hair dye.Hope this helps!! And good luck!
