Hi. I recently coloured over my highlighted hair with a permanent 'natural light brown'. As the color underneath had orange tones in it (which was the reason I went over it with brown), the colour I have now is brown with a lot of red and orange tones in it. My highlights are coming through on top, which is OK. HOWEVER... I really really want to get rid of the warm tones and have ash ash ash. I would also quite like to get some highlights, but not orange or 'yellow'! Something natural. Could I get ash LOWlights to go over the dark that is there to counteract the warmth, and ash highlights as well? Or should I just ask for highlights (what colour? ) and then an ash toner?
I just want to know what to say to my hairdresser so he knows what I'm talking about and what I want...

If you want your hair to look more brown, minus the red/orange tones, then ask the hairstylist to apply an ash base color on your hair. When you go to the hair salon, don't be afraid to ask questions or tell them what color you want.
