When Kérastase prepared to launch Première, its new haircare line representing a decade of decalcifying research, the L'Oréal Group faced a complex messaging challenge. They needed to effectively communicate both the technical innovations—removing calcium buildup from hard water that leaves hair dull, stiff, and damaged—and the product’s routine and quality in one cohesive narrative.

Première stands out from all our other ranges for two main characteristics. It's L'Oréal's first decalcifying treatment. Specifically, the Pure Acids Complex (Citric Acid and Glycine) removes excess calcium from the fiber, giving hair shine and softness. The second characteristic is its double repairing action. The hair's keratin bonds are repaired, while simultaneously the acidic pH of its ingredients closes the cuticles, sealing the fiber. This allows us to reduce hair damage while strengthening it at the same time,

The complexity of conveying multiple elements—the decalcifying technology and repair benefits message points, the correct product usage, and Kérastase's premium positioning—called for a sophisticated full-funnel strategy. The brand chose Amazon Ads to build an integrated campaign that would showcase the product's unique benefits in premium environments, while driving measurable business results.

A full-funnel strategy: From Prime Video ads to a custom landing page

Launched during September and October, when consumers are seeking haircare that combats summer damage, the campaign utilized Amazon Ads full-funnel capabilities to layer these messages throughout the consumer journey. Initial awareness of the Première line and benefits was built through premium streaming ads on Prime Video and Fire TV, while detailed product education on the correct routine steps to follow was delivered through a custom landing page developed by Brand Innovation Lab, Amazon’s global team of strategists, creatives, and technologists. The experience culminated in immersive product pages, including interactive videos, that showcased the five-product range, ensuring each benefit was clearly communicated and understood by the target audiences.
