I used to use. A lovely lady locally too called Busybee on this forum. She was lovely and competetivly priced. We lost touch over the years but maybe if you do a search she is still around? I use Bromley these days as I can just pop in when it suits me rather than have to book an appointment.
The tint is more tricky. I do it myself now as I know I'm very picky and loathe the too warm colour that is often used in salons, prefer them more ashy. Good luck and please do let me know if you find somewhere.
