Hi all have got a client that's has got a warm base 7 root of about 2 inches and hilift and bleach foils so quite blonde . Her friend as been colourring her hair so I will be doing a patch and strand test . Not sure if the best way forward is to global colour and highlights or highlites and lowlights ? I use magirel and was thinking of using 7.1 to neutralise the warmth at root but a bit unsure of blonde mid lengths and end . Her hair is so long ? Advice would be really appreciated thanks sally
