K18 appoints chief marketing officer. The biotechnology hair care brand has hired Kleo Mack, who joins from previous roles at Glossier and Shark Beauty, to create more resonant 'brand moments,' said co-founder Suveen Sahib. 09 April 2026 K18, the biotechnology hair care brand, has appointed Kleo Mack as its chief marketing officer, The Business of Beauty can exclusively reveal. Mack assumed the role on April 8. She succeeds Audrey Dorfman, who served as the brand's CMO between May and Sept. 2025. She joins the brand from Shark Beauty, where she has served as senior vice president and chief marketing officer since May 2025. Previously, Mack held senior leadership roles at L'Oréal as well as Glossier, where she served as vice president of brand and CMO throughout her 2021 to 2025 tenure. "K18 is a very community-driven brand. I wanted to find someone who was consumer obsessed, and had experience in culture-shaping marketing," said Suveen Sahib, the brand's co-founder. "Kleo was the obvious choice." At Glossier, Mack spearheaded buzzy campaigns like signing Olivia Rodrigo as the brand's first celebrity ambassador. Together, Mack and Sahib will work on the brand's storytelling, championing its science-first ethos and curating fewer, more resonant "brand moments." The brand is currently conducting a global tour to promote its new TripleBright blonde shampoo, identifying cities suffering from elevated hard-water exposure to meet potential new customers consumers. This strategy of resonating culturally within specific cities and championing stylists will be key to developing the brand globally, added Sahib. On Wednesday, the brand announced a Pro Artist Programme to further support its network of professionals. "When we win in those cities and those cultures support our wins, our stylists win," Sahib added. Sales of high-end hair products grew 32 percent in 2021 and more brands are debuting science-backed scalp serums and hair repair treatments in response to customer demand.
