I dyed my hair this afternoon with Nutrisse Morello Cherry. My hair was previously dyed a medium brown but I'd left it weeks and weeks and have been using Head & Shoulders to fade it as I was going to have highlights but changed my mind.
It's gone very red on the top/roots, and really really dark on the bottom. I understand this is down to colour build up etc etc. I've washed it with T-gel and H&S a few times but it still looks stupid.
If I get another colour tomorrow, say dark brown, and apply it as if I was doing a root touch up, would that work? I need it doing by Monday morning as I have to have my photos doing for work, so I won't find a hairdresser open tomorrow
