Has anyone embraced their greys and had highlights to blend them in? Looking for recommendations for colourist.

[LetterOfTheLawFella]

I want to blend in my greys by having grey highlights put in.

Can anyone recommend a really good colourist as I want this to look good!!

I'm based in Hitchin but would be happy to travel over Herts / Beds / Cambs or even London.

As far as I know grey highlights are achieved by putting a toner on blonde ones, rather than the actual highlights being coloured grey iyswim?
