Driving 32% Revenue Growth with WhatsApp & SMS for Dense Hair Experts
Dense Hair Experts increased eCommerce revenue by 32% using Zefir

Most teams know what bad workflows feel like: clunky handoffs, endless follow-ups, siloed tools, and time lost to manual effort. It’s a low-grade friction that becomes normalized—until it isn’t. When things break, they break loudly. And by then, you’re already playing catch-up.
Dense Hair Experts is a UK-based eCommerce brand specialising in advanced hair care solutions. With a fast-growing customer base and strong demand for its products, the brand needed a more effective way to drive repeat purchases, recover abandoned carts, and scale promotions beyond traditional email marketing.
Email alone was no longer delivering the reach, engagement, or conversion rates required to support growth. Key campaigns were often missed, and high-intent shoppers who abandoned checkout were difficult to re-engage.
To solve this, Dense Hair Experts partnered with Zefir to implement a high-performance WhatsApp and SMS marketing strategy focused on revenue, automation, and scale.
Building a Revenue-Focused Messaging System
Zefir helped Dense Hair Experts design and deploy a fully automated messaging engine built around three core pillars:
Cart recovery automation
Post-purchase cross-sell journeys
Performance-driven promotional campaigns
Each element was designed to capture demand at the right moment, increase average order value, and maximise customer lifetime value.
Abandoned Cart Recovery with WhatsApp & SMS
A significant portion of Dense Hair Experts’ website visitors showed strong purchase intent but failed to complete checkout. Previously, these users were only targeted via email — often too late to recover the sale.
With Zefir, the brand implemented real-time WhatsApp and SMS cart recovery flows that:
Triggered immediately after cart abandonment
Reminded customers of their selected products
Reinforced product benefits and urgency
Drove users back to checkout with one-click links
These messages reached customers directly on their mobile devices, where open rates and engagement were significantly higher than email.
As a result, Dense Hair Experts recovered a large volume of previously lost revenue from high-intent shoppers.
Post-Purchase Cross-Sell Journeys
The customer journey didn’t end after checkout.
Zefir enabled Dense Hair Experts to launch intelligent post-purchase flows that:
Recommended complementary hair care products
Promoted bundles and refills
Encouraged repeat purchases
Increased average order value
Customers received relevant, personalised product suggestions at the right time — without overwhelming them.
This transformed WhatsApp and SMS into long-term revenue channels, not just short-term promotional tools.
Campaign Execution at Scale
In addition to automation, Dense Hair Experts ran structured WhatsApp and SMS campaigns aligned with:
New product launches
Seasonal demand
Limited-time promotions
Stock availability
Special offers
Zefir’s platform allowed the team to plan, schedule, and execute campaigns with full control over:
Audience segmentation
Message timing
Compliance
Performance tracking
Revenue attribution
Each campaign was optimised based on real-time performance data, creating a repeatable system for high-ROI growth.
Measurable Business Impact
After implementing Zefir, Dense Hair Experts achieved:
32% additional revenue from WhatsApp & SMS

Improved cart recovery rates

WhatsApp and SMS became core revenue channels — not just support or notification tools.
