I've been having a full head of highlights every few months for quite a while now. I am getting a bit bored of it to be honest but the last time I tried to go darker I looked dead 
I was wondering about going darker but keeping the tips light to avoid the corpse look but still cut down onthe number of times i visit the hairdresser. Can it be done by adding darker highlights to the roots or will I need to dye the lot then lighten the ends? I can pop in to the salon to see what they think but I just wondered if anyone had done it before?
