Port Sunlight has just swallowed a £150 million investment from Unilever, and hair care R&D is the loudest beneficiary. The Wirral, UK site — home to roughly 2,000 staff split between advanced manufacturing and research — completed the upgrade in 2026, with Unilever's beauty leadership framing it as a supply chain reset that starts at the lab bench.

What did the £150 million actually buy?

The cash landed across two big buckets. Manufacturing lines got an overhaul inside the home care operations. A brand-new advanced automated distribution centre also came online, designed to "strengthen" the company's UK supply chain "from manufacturing through to delivery," per Unilever's own framing of the project.

On paper, that looks like a logistics story. In practice, it isn't. Hair care saw "some of the largest advancements" of the lot, according to Jason Harcup, Chief R&D Officer for Unilever's Beauty and Wellbeing Division, who walked trade press through the factory floor during a recent visit. Takeaway: the cash is real, but the science is the headline.

Why is hair care leading the build-out?

Harcup frames the science push as a business call, not a vanity project. "From a science and R&D point of view, [the focus on hair care] completely aligned with the business," he says. Translation: hair care is where the margin story lives right now.

The word he reaches for next is premiumisation. "We are trying to premiumise actually with a fair amount of success into different formats." That is a quiet admission that growth is moving up the price ladder, not across bigger bottles on the bottom shelf.

Unilever has spent 70 years shipping hair care innovation, and Port Sunlight has long sat at the centre of that pipeline. The 2026 spend converts the site into Unilever's main engine for premium hair formats, with R&D and manufacturing now physically and operationally intertwined. Takeaway: lab and line are no longer separate conversations.

What changes for salons and stylists?

A premiumisation tilt at this scale usually shows up in three places: more sophisticated active systems, sharper conditioning claims, and tighter strand-by-strand performance language on the back of pack. Professional buyers will have a sharper story to tell clients who now expect hair science to read like a benefit list.

The shift also signals that Unilever is willing to trade volume for margin in hair — a meaningful pivot for a category long priced on litres moved rather than innovation sold.

Salon-exclusive launches, prestige-tier restages, and pro-channel distribution deals all become more plausible when the factory behind them runs at premium speed. Takeaway: the mass-market shelf may start behaving like a prestige one.

What does the timeline look like?

Port Sunlight's new automated centre sets the pace for how fast Unilever can roll new hair formats into UK and export markets. Watch the launch calendar that follows — the distribution muscle built this year will decide which regions get new SKUs first.

The first wave of new launches out of Wirral will show whether premium hair can scale at the speed Unilever's premiumisation strategy demands, and whether the automated distribution centre delivers the export throughput the £150 million was meant to unlock.
