I am mid 40s, about 40% grey. My natural hair is a very cool dark brown. When I go to the salon and ask for a colour similar to my natural it tends to be great initially, then fade brassy/warm very quickly. I use the shampoo sold to me by the salon but I run 4-5 times a week so have to wash a lot. I’ve been told that this is because I have natural warmth in my hair (which I struggle to believe as I’m very cool toned). I’ve tried highlights and balayage to try blending but that seems to just get blonder over time. Currently I’m 10 weeks from my last colour as considering paying through the nose for grey blending and they ask for 3 months regrowth first and I don’t actually hate the silver coming through as I think the cooler tones work best for me. But I’m not sure I’m ready to go grey just yet!
This must be a common scenario- is there any way to keep a cool brown colour or are the only choices going brassy or going grey?
