The professional event dedicated to the beauty business, hair, aesthetics, make-up and nails, gathers 170 exhibitors and runs through September 14-15, 2014. First appearing in France around 2010, "nail art" gained popularity on social media and saw a boom during Covid lockdowns, as online do-it-yourself tutorials gained traction. Nail salons have since popped-up across the country, seemingly as numerous as bakeries, and represent a lucrative multi-million euro industry.
