Home hair dye help

[number277]

Hey,
I've just done a patch test and hoping to dye my hair on Friday. If I do have a reaction is it possible to dye my hair without actually touching my roots? I could do foils but I know I won't be able to do the back and the only person who could is DP and there's noway in hell I think he could do it right. Hell fuck it right up & go in a strip if I tell him he's doing it wrong!

Not strip-although that would be entertaining

Is this for highlights or is it dye?
A hairdressers can apply bleach without touching root but not dye. It's gonna look bad and you doing it yourself you will get it on your skin. If you react then don't use it. Not worth it.
