Some brands you recognise without even looking. You walk into a shop, or open a parcel that’s been waiting for you for days, and before you’ve seen the logo you already know whose it is. It isn’t magic: it’s your sense of smell. And it’s probably one of the least explored — and most fascinating — territories in the world of labelling.
For those of us who work every day on strengthening a brand’s identity through its labels, scent raises a question we rather like: if a label can be seen and touched, why not smelt as well? The short answer is that yes, it can. The longer one is that it has to be done well, and not always.
Why do smells lodge so firmly in the memory?
Let’s start with what the science says, because there’s rather more here than intuition. Smell is the only one of our senses that reaches the limbic system almost directly — the part of the brain that handles emotion and memory — with barely any intermediate filters. That’s why a smell can carry us back to a specific moment with a vividness that a photograph rarely manages.
Rachel Herz, a researcher at Brown University, has spent decades studying this phenomenon (the so-called “Proust effect”), and her work consistently shows that memories triggered by smells are more emotional than those prompted by other sensory cues. In her neuroimaging studies she found that personally meaningful smells activate the amygdala and the hippocampus more than comparable stimuli do — precisely the areas where emotion and lasting memory are cooked up.
Translated into brand language: a well-chosen scent doesn’t inform, it settles in. And once it’s inside, it’s far harder to erase than a colour or a typeface.
How you get a scent onto a label
The most common technique is microencapsulation. In essence, the fragrance is sealed inside microscopic capsules that are worked into the label’s ink or its material. The scent stays protected and stable for a long time, and is only released when the user rubs or presses the area — the well-known “scratch and sniff” applications. It’s the same technology you’ve been seeing for years in perfume magazines, adapted to the world of textiles and labelling.
This opens up several scenarios: a brand label that smells of the house fragrance, a hangtag that reinforces the product’s universe at the point of sale, or an olfactory detail designed purely for the unboxing moment. Scent stops being ambient and starts travelling with the garment.
When it makes sense to use it (and when it doesn’t)
Here comes the honest part. A scent on the label isn’t something to put on everything. It works when:
- The brand already has an olfactory identity (or wants to build one).
If your shop smells a certain way, having the label carry that smell on closes the loop. Coherence is everything: a scent that doesn’t fit with the rest of the brand creates noise, not memory. - The product lives or dies on the experience. Cosmetics, lingerie, premium fashion, childrenswear, gift packaging — categories where the moment of discovering the product matters as much as the product itself.
- You’re after differentiation on a crowded shelf. When everything is competing for the eye, smell is an almost untouched channel.
It’s also worth thinking twice when the scent might compete with the product itself (perfumery, food), when your audience may be sensitive or allergic, or when it’s a technical or workwear garment where the smell simply adds nothing. Adding a scent because you can isn’t a strategy; adding it because it says something about the brand is.
A couple of things to bear in mind
Two practical notes before diving in. First, durability: the intensity of the scent gradually wears out with each activation and over time, so you need to gauge the shelf life you’re expecting carefully. Second, regulation: fragrances are subject to rules on allergens and substances, especially in products worn against the skin or aimed at children. Working with fragrance suppliers who meet the industry’s standards (IFRA and the corresponding European regulations) isn’t optional.
Which scent for which brand (a quick guide)
There’s no magic formula, but there are scent families with fairly stable associations. The golden rule stays the same: the scent has to sound like what the brand already is, not like whatever “smells nice” in the abstract.
- Citrus (lemon, orange, bergamot): freshness, cleanliness, energy and youth. A good fit for casual fashion, sportswear or fresh products. They also have a reputation for holding on to customers — one study suggests a citrus smell can push sales up by around 20%.
- Vanilla: warm, welcoming and almost universally liked. It creates an emotional connection and invites people to linger, which is why it works so well in retail. Curiously, touches of vanilla or cinnamon make customers lean towards the more expensive products.
- Lavender and chamomile: calm and relaxation. The territory of wellbeing, personal care, intimate wear and serene premium.
- Floral and powdery: elegance, femininity and sophistication. Very natural in cosmetics, lingerie and boutiques.
- Woody, amber and musk: luxury, character and sensuality. The option for premium boutiques or more masculine lines.
- “Clean” (cotton, linen): comfort and textile freshness, almost the smell of freshly laundered clothes. Very much at home in the world of garments.
- Leather and gourmand notes (coffee, chocolate, cinnamon): authenticity and pleasure. Harley-Davidson is the classic example of embracing leather and metal as part of the identity.
One figure for the workspace side of things, not just the sales side: certain office scents have been documented as helping to reduce mistakes by up to 21% and boost productivity by around 14%.
Brands already doing it (and what to learn from them)
- Abercrombie & Fitch. The textbook example in fashion: their Fierce fragrance became part of the brand’s identity, to the point where you could smell it from outside the shop. The lesson cuts both ways: it was hugely recognisable, but its excessive intensity ended up bothering sensitive customers or those with allergies, and the brand eventually toned things down while keeping a more discreet signature scent. More isn’t better.
- Nike. The most quoted figure in the field: scenting the shop with a subtle floral note increased the intention to buy trainers by almost 80%.
- Singapore Airlines. The best-constructed “scent logo”: their Stefan Floridian Waters fragrance is on the hot towels, in the cabin and even in the crew’s perfume, creating a coherent, recognisable experience that sets them apart from the competition.
- Hotels (Hyatt, Westin, Ritz-Carlton). The sector that popularised the signature scent: Hyatt uses a soothing green-tea note that forms part of its global identity and lets guests recognise the brand wherever they are.
The common thread: in every case the scent isn’t just any perfume, it’s coherent with what the brand promises. And the most useful lesson for a label is precisely Abercrombie’s — subtlety and inclusivity (thinking about allergens and sensitivities) matter just as much as strength.
In short, smell is the sense that best etches a brand into the memory, and the label is one of the few places where that smell can travel straight into your customer’s hands. Used with intent — coherent with the brand, in the right category and well resolved technically — a scent turns a label into something that isn’t only read: it’s remembered.
And in a market where almost everything looks alike, giving people something to smell may be the difference between going unnoticed and staying with them.
