I got my hair coloured yesterday, I had used a red box dye and wanted to change the colour to a mid brown with highlights. The hairdresser said she’s need to a go darker brown to cover the red, which I was ok with, and said the o really effect would be lighter with the highlights. The base colour fit my hair is fine, a bit dark but ok, but the highlights are grey which is not the effect I was looking for at all.
Is it reasonable to contact her and ask her to fix it in some way?
