I have a question about re-dying my hair red. Right now I have platinum hair with dark/medium brown roots (my natural color). I would like to go back to copper red (which I was previously)...
My question is, if I'm using one shade of copper blonde for the whole head, do I use a higher percentage developer for the roots than the rest of my hair in order to achieve an even color? Or can I just use one developer + dye mixture for the whole head. I'm ok with roots being a slightly darker red since it will make regrowth look a bit better (I think?). Any advice?
