Of the 1.5 million units sold, 1.35 million weren't shampoo. That's the cumulative sales tally racked up by Refield, a hair-loss care brand, since its founding. Ninety percent of that total came from leave-on ampoules and serums — products applied to the scalp and never rinsed out. Refield built its brand around a functional anti-hair-loss shampoo, putting it front and center in every campaign. But the product customers kept coming back to pay for was something else entirely.
Constant, the company behind Refield, held a press conference in Seoul this year to announce it was discontinuing its hair-loss shampoo altogether and repositioning itself as a "scalp science brand" built around ampoules and serums. It was a decision to retire the very product the company had led with since day one. And the evidence behind that call wasn't a hunch — it was years of accumulated sales data. Customers had reached their conclusion first; the brand simply caught up. Retracing that sequence raises a question that lands directly on solo founders and small business owners, too.
The product the brand pushed and the product customers chose were not the same
In the hair-loss care market, shampoo is the most familiar entry point. Search "hair loss care" on any Korean portal and shampoo is the first category that surfaces. Marketplace category structures and drugstore shelf layouts are both built around shampoo. That's why most brands entering the hair-loss category lead with a shampoo as their flagship product — and Refield built its brand within that same framework, leading with a functional shampoo certified by Korea's Ministry of Food and Drug Safety for alleviating hair-loss symptoms, while running ampoules and serums as a secondary line sold alongside it.
But actual sales told a different story. Because ampoules are applied directly to the scalp and left on rather than rinsed off, their active ingredients stay in contact with the skin longer and in higher concentration. Shampoo, by contrast, washes most of its active ingredients away during use. Customers noticed the difference — and expressed it through repeat purchases. Throughout Refield's entire sales history, ampoules and serums consistently accounted for around 90% of volume. The products with the most reviews, the user posts shared voluntarily on social media, the testimonials about visibly changed scalps — all of it clustered around the ampoules.
This pattern held for years. While the brand kept leading with shampoo, customers kept quietly choosing ampoules. When that gap persists not for a few months but across a company's entire sales history, it isn't a marketing message that failed to land — it's customers reinforcing their own choice through direct experience, purchase after purchase. That growing distance between what the brand said and what customers actually bought is what ultimately pushed Constant to retire the shampoo.
Walking away from a certified shampoo doesn't come free
It's worth being clear that this wasn't an easy call. Korea's hair-loss care market is worth hundreds of billions of won, and earning functional certification takes considerable time and money. Given the distribution channels and customer base already built around the certified product, discontinuing it voluntarily could look, from the outside, like an unusual move — one that risks leaving an opening for competitors to step into.
There's a reasonable counterargument, too. Some in the industry believe an ampoule-centric portfolio could limit new-customer acquisition over the long run. Consumers just starting out with hair-loss care tend to reach for shampoo first — it has a low barrier to entry, familiar usage, and is often priced lower than ampoules. Discontinuing shampoo narrows that entry channel. No matter how high the repeat-purchase rate among existing customers, a shrinking inflow of new ones can still slow a brand's overall growth. On top of that, persuading consumers to adopt a "rinse-free scalp care routine" is a communications challenge that requires educating an entire category — and whether that education pays off efficiently in marketing time and cost remains unproven.
These concerns are legitimate. Whether Refield's pivot goes down as a successful brand transformation won't be clear for another two or three years. Still, the basis for the decision itself — shifting the center of the business toward the product customers had chosen, repeatedly, over a long stretch of time — carries a different kind of weight, because it starts not from market forecasting or founder intuition but from sales data that had already happened.
Your sales record is already writing your next business plan
There's a point in Refield's story that connects directly to solo entrepreneurs and small business owners: this wasn't a strategic pivot backed by tens of millions of dollars in investment. It grew out of simply re-reading sales records the company already had.
You can ask the same question of your own business right now. Does the product or service you consider your flagship match the item that actually generates repeat purchases or renewals? If it doesn't, how big is that gap?
If you're a creator selling content, check your monthly revenue breakdown for which topics and formats keep generating payments or subscription renewals. Whatever content draws an unusual number of thank-you messages — that's your equivalent of Refield's ampoule. If you run online courses or consulting, start by tracking which sessions bring students back after they've completed the program, or get referred to friends. If you sell physical products, look first at the SKUs that get quietly repurchased without refund requests — then compare that list against whatever you're featuring most prominently in your marketing materials.
These signals are already sitting inside your business, with no extra research required: sales records, customer inquiries, review text, repurchase cycles. Without a routine of pulling this data out and reading it every quarter, you end up like Refield — recognizing the pattern only after years have passed. In a business's early days, the founder's hypotheses and planning should set the direction. But once operations run past the one-year mark, customer choices start accumulating as data — data that may carry signals different from what the founder originally planned. I'd argue that a single habit of reading these signals shapes a business's direction more than ten new product ideas combined.
Brands that keep operating without pausing — even if the execution isn't polished — build up a thicker layer of customer-response data over time. A brand that adjusts its direction through actual sales and repeat purchases ends up with sturdier grounds for decision-making than one that designed a "perfect" product lineup from the start. Refield could only walk away from shampoo because it had years of accumulated sales data behind it. Without that data, the decision would have been far harder to make.
A sales ledger shows actual purchasing behavior with none of the assumptions built into a business plan. Before dreaming up a new product, open your own sales records and check where the revenue keeps repeating. If customers have already revealed their choice through repeat purchases, finding that item is the next step.
