Duffy is one of the leading lights in session styling. Having left school at 15 and following a three-year apprenticeship at Vidal Sassoon, Duffy was thrown into the deep end when he met Eugene Souleiman who took him backstage and showed him a world outside of the salon.

After time out of the industry traveling, snowboarding and following a stint in his parents’ antique business, Duffy reconnected with the influential people he’d met early in his career. This led to work with David Sims, Peter Lindbergh, Glen Luchford, Patrick Demarchelier, Willy Vanderperre and Craig McDean, among many others.

Youth culture and subcultures have always been a huge focus for Duffy's work.
