Kao USA has launched a review of creative responsibilities for global brands John Frieda, Jergens, Biore and Curel. In a terse press release, the company said it and incumbent Kirshenbaum Bond Senecal + Partners have “mutually agreed to separate.” “We are deeply grateful to KBS+P and their partnership for the past ten years,” said Dave Muenz, regional executive officer for Kao’s mass business. “We had a good run and look forward to selecting a new agency partner.” Media spending on the brands in play was not immediately available. The review does not affect other Kao USA agencies, such as those that buy media or create digital ads in key markets. Kao has retained Joanne Davis Consulting/SCAN International manage the search, which is expected to conclude by May.
