What Shampoo Bars Can Teach Us About Sustainable Innovation.

For years, brands have been told that consumers want more sustainable products.

And they do.

The challenge is that wanting something and buying it are two very different things.

When Garnier wanted to bring shampoo bars into the mainstream, the question wasn’t simply whether consumers liked the sustainability credentials. It was whether they were willing to change long-established habits, trust a completely different format and, in many cases, pay more for it.

The insight

The research uncovered a tension that appears across countless sustainable innovations: Consumers are attracted to the environmental benefits. But they buy based on performance.

In beauty particularly, efficacy consistently outperforms sustainability as a driver of choice. Consumers want products that work, brands they trust and solutions that make them feel good. Sustainability is often a welcome bonus rather than a primary purchase driver.

“Consumers say they want sustainable products. They buy products that work.”

The challenge

Shampoo bars faced three barriers:

• They looked unfamiliar.
• They were often more expensive than standard shampoo.
• Consumers weren’t convinced they would work as well.

That meant the innovation challenge wasn’t simply creating a more sustainable product.

It was creating confidence.

• Confidence that the product would deliver the same results.
• Confidence that consumers weren’t making a compromise.
• Confidence that the price premium was justified.

“The biggest barrier to shampoo bars wasn’t sustainability. It was confidence.”

Why this matters beyond shampoo bars

This isn’t a beauty story.

It’s an innovation story.

Many sustainable innovations fail because they focus on what is better for the planet before proving what is better for the consumer. The most successful sustainable innovations don’t ask people to make a sacrifice. They make sustainability feel like an added benefit to a product that already delivers against the fundamentals.

The 2CV perspective

At 2CV, we often see brands attracted to emerging trends and innovation spaces. The critical question isn’t whether a trend is growing.

It’s whether consumers are willing to change behaviour.

Research helps brands understand where the barriers sit, what trade-offs consumers are prepared to make, and how to create confidence before committing significant investment behind a launch.

Innovation succeeds when it is not only sustainable and disruptive, but genuinely meaningful to consumers.
