Charlotte is an absolute dream. I've been to top salons throughout the UK, US, and and Canada, and she's as good as they get. She's friendly but not overbearing, totally listens to her clients' needs and desires, has a positive, welcoming spirit, and is truly gifted at her craft. My cuts from her last a month longer than with other stylists.
My experience with colorists has been more hit-or-miss (more in terms of attitude than results), but, in general, I recommend Parlour.
