This details how Kao’s haircare division successfully revitalized its brand by integrating Brand Generated Content (BGC) with User Generated Content (UGC). To overcome declining market share, the company moved away from traditional mass advertising toward a strategy where official brand messaging establishes a core identity while influencer and customer reviews provide social proof.

By carefully analyzing individual influencer styles, Kao ensures that diverse online testimonials remain aligned with their central "restorative beauty" concept. This synergy builds consumer trust and increases organic social media engagement, which the company identified as a primary driver of sales. The transformation also required internal restructuring into agile, cross-functional teams to quickly adapt marketing tactics based on real-time feedback.

It illustrates how a century-old corporation achieved a competitive advantage by fostering a collaborative brand story between the company and its audience.
