1 Campaign, 100+ Ads, 70% Engagement: Inside Wella's AI Audio Success with AudioStack
Azerion used AudioStack's agentic production platform to turn one script into 100 personalized audio ads across the UK — proof that AI-driven personalization can move even a sensitive, hard-to-message category to act.

Wella's Nioxin Pro Clinical line saw 70% of exposed listeners take, or intend to take, action after hearing a personalized audio campaign built on AudioStack's platform, according to brand lift results published by Wella, Azerion, and Digitas.
Azerion, working with media agency Digitas, used AudioStack to turn a single Nioxin creative into 100 distinct audio versions, tailored across two audience segments (women 25–45, men 20–35) and 24 UK locations, at a fraction of the cost and timeline a manual, studio-based build would require.
The brand lift study, measured by On Device Research against a control group, found:
70% of exposed listeners took or intended to take action — purchase, research, or word of mouth
21-point recall lift and 22-point awareness lift among listeners who had personally experienced hair thinning
77% said the branding was clear, addressing a persistent challenge in audio: listeners can't glance back at a visual to confirm who's speaking
The campaign builds on earlier research from Azerion and Differentology showing AI-generated voice performs on par with human voiceover, even though most listeners assume a human would win. Nioxin became the live commercial test of that finding, in a category where a generic script typically falls flat.
“The results mark a shift away from one-size-fits-all messaging and into personalisation at scale. More localized, relevant messaging built a genuine connection with our audience.”

EMEA Media Director, Wella
“Hair thinning is experienced differently for each person. Relevance in the moment — not just reach or frequency — is what drove listeners to act.”

Insight and Strategy Director, UK, Azerion
“Personalization is now the new benchmark for effective audio — not a nice-to-have.”
Lisa McAllister
Group Media Director, Digitas
“This is exactly what agentic production is built for. One team gave us one script, and our platform turned it into a hundred versions that actually speak to the person hearing them. Azerion and Wella didn't just save time; they proved that personalization at this scale drives real commercial results. That's the shift we want every media organization to be able to make.”
