L’Oréal’s Professional Products Division (PPD) is announcing several strategic leadership appointments across Redken, Color Wow, and L’Oréal Professionnel Paris. 

These moves underscore the division’s continued investment in innovation, education, category leadership, and long-term growth within the professional salon landscape.

Mounia Tahiri — General Manager, Redken US  

Following her high-impact tenure leading the L’Oréal’s PPD team, Tahiri steps into the GM role at Redken. 

Her appointment follows a series of transformative achievements across PPD, including leading Biolage to double-digit growth, architecting Ulta’s prestige haircare omni-model, and most recently guiding the L’Oréal Professionnel Paris brand past the $100 million in sales milestone while strengthening its tech-driven identity. 

Tahiri now takes the helm of Redken as the brand expands its professional relevance, education ecosystem, and cultural influence.

Guillaume Duez — General Manager, Color Wow  

With the close of L’Oréal’s acquisition of Color Wow, Duez will lead Color Wow’s team alongside the brand’s founder & CEO Gail Federici. 

Duez brings PPD experience across the DMI, marketing, and GM roles, including propelling Kérastase and Shu Uemura to over 4x growth and elevating Redken to the #1 rank in Circana and Haircare Brand of the Year at Ulta. 

Duez’s leadership will guide Color Wow through a phased integration while maintaining the brand’s creative spirit and momentum across styling and problem-solution innovation.

Julie Fortier — GM, L’Oréal Professionnel Paris  

Most recently leading the division’s education transformation, Fortier has helped modernize PPD’s education systems, building digital foundations, developing transversal structures, and expanding reporting and KPIs across brands. 

Before joining the U.S. team, she spent 18 years at L’Oréal Canada. She served as GM for Kérastase & Shu Uemura, where she doubled the business in three years. Her blend of commercial expertise, digital vision, and education depth positions her to accelerate L’Oréal Professionnel Paris’ growth and strengthen its salon partnership strategy.
