My roots are copper red and the rest of my hair is dark brown red, I have a business trip in a couple weeks and need to get this corrected. Should I try using colour fix to stripp out the colour? The lady from Sally's beauty supply told me not to unless I was a professional! But I have heard others have done this with success. Does anyone have any words of wisdom? I don't want to make it worse and I can't afford to go to the salon to correct it.

Follow the directions and you'll be fine.
