Sorry, this takes a bit of explaining:
My naturally very dark brown is now about 40% grey. I've graduated from dark brown box dyes, to mid brown ones, but I get that strap of white appearing at my parting after two weeks, and it's all a bit dead and boring.
Think I need to be lighter and multi-tonal, but I can't afford to maintain that at the hairdressers. In a moment of madness, I used a colour remover. Amazingly that's left me with a pretty good balayage effect (where peroxide from the permanents lifted the longest sections the most), plus my look greys lighter throughout, which has made the contrast with regrowth much less harsh.
The issue is it's all a bit warm for my cool colouring. My hair has a lot of red in it which comes through whenever lightened, which is one of the reasons I've stuck with brown to date. I've slapped on a purple toner, but suspect I might need to put something permanent with ash over the top, and then maintain by keeping that dabbed on at the roots. Does that sound a plausible plan? And if so, does anyone have any recommendations - thinking maybe a dark ash blonde? TIA
