My hair is darkish brown - a level 5 apparently. I'm starting to go slightly grey and thought a good idea would be to add highlights to try to blend greys as they come through. I wanted ashy toned highlights- either blonde or lighter ashy brown, just so my hair isn't as stark dark brown with obvious greys.
Hair colourist (top stylist) said it wouldn't be possible and I'd have to have reddish warm highlights. I understand hair goes through a red phase when lightening but I had blonde highlights many years ago so don't understand why I can't have what I'm looking for? It will go to a light level, so then surely it's just about toner?
