Nathan joined Trevor Sorbie aged 17, and has now been there for more than 20 years; there’s literally nothing about the salon’s philosophy, techniques or background that he doesn’t know.  His impressive celeb clientele reads like a who’s who of gorgeous ladies: Cheryl Cole, Gemma Arteton, Donna Air, Louise Redknapp, Helen Mirren, Gillian Anderson, Emma Bunton, and Denise Van Outen to name a few.
