Simple Shampoo (Gentle Care): Is It Really Fragrance Free?
You reached for Simple because the bottle said fragrance-free, and the bottle felt like a promise you could trust. The ingredient list tells a different story. Chamomile and geranium oils sit there in the INCI, quietly contradicting the front label, and in a hot shower you can smell them. This is a review about which of those two documents to believe.
Tested in hard water (South Downs chalk). Single-blind. No conditioner used in shower test.

Sensory scorecard
Smell and texture — the findings
This review examines two dimensions: smell and texture & behaviour.
What this means in practice: the smell is faint, a light citrusy or grass-like note cold, a faint chamomile-floral character in heat, consistent with the essential oils listed in the INCI. Nothing lingered after rinsing. The fragrance-free claim on the label does not hold. Fragrance-active essential oils are present and detectable. For users who react to chamomile or geranium oils, or who require a product genuinely free of all fragrance-active ingredients regardless of source, this does not qualify. <a href="https://boxofsmallthings.com/faith-in-nature-natural-shampoo-fragrance-free-sensory-review/">Faith In Nature</a> is the clearest alternative.
What this means in practice: the texture is the most practically difficult aspect of this product in use. The gel is sticky and not spread easily – an application covers only the top of the head. A double dose was consistently required, and spreadability remained poor. The squeak on rinse was intense like the styrofoam variety: not merely clean-feeling but a specific quality of friction that constitutes its own category of sensory difficulty. The cap also squeaks and collects product residue from the first use, both findings noted for ongoing monitoring. The fast rinse is the one result this product delivers more cleanly than almost any other in the batch.
Case notes
What was found
Simple is a drugstore staple. It is common in supermarkets in the UK and widely recognised in the US. The brand has built its reputation on a sensitive-skin positioning consistent for decades: no unnecessary ingredients, no harsh chemicals, designed for reactive skin. That track record is real. The label claims on this particular product do not fully support it.
The ingredient list was examined after the shower, the experience having failed to match the packaging. The front of the bottle reads fragrance-free. Chamomile Oil and Geranium Oil appear in the INCI. The front reads sulfate-free. Sodium Laureth Sulfate is the first listed surfactant. The brand’s “no artificial perfume” framing is technically accurate because both oils are naturally derived. The technical accuracy is doing considerable work for a product whose fragrance-free claim is the reason most users will have selected it.
The ingredient list was reviewed with some care. Chamomile Oil and Geranium Oil were both present. The term "fragrance-free" remained on the front of the bottle. The investigation sat with this for a moment.
In practice, the smell was faint; detectable in the shower but not aggressive. A light citrusy chamomile note, consistent with the oils listed. The more significant findings were texture and cleansing behaviour. The non-lathering formula does not spread through hair. it remains where placed, requiring a double dose to cover the scalp. The rinse was the fastest in the batch. The post-rinse squeak was the styrofoam variety, a specific quality of friction that registers as its own category of sensory difficulty rather than merely an indication of cleanliness. Next-day scalp itching was also recorded.
SLES is the lead surfactant, which is firmer than the “gentle” framing suggests. CAPB is present. The pH of 6 is scalp-friendly on paper; the surfactant combination overrides that in practice. For a genuinely fragrance-free formula with a comfortable clean, Faith In Nature is the most direct alternative. For non-lathering without the squeaky clean, Vanicream uses a glucoside system that also produces minimal foam see the low-foam guide for how both compare. The full batch comparison shows how Simple sits among the others.
What was tested
The tests
200ml comfortably hand-sized, slightly grippy plastic. The cap has a pleasing snap but a slight squeak on both opening and closing. Closing requires both hands and a little force. Product residue appeared on the cap from the first use.
Medium-thick, slightly gooey gel. Sticky enough to stay where placed rather than spreading. In the hand: slightly stringy and slow-moving. Leaves residue on the cap from the first use.
A faint, slightly unusual smell: citrusy, grass-like, mild. Present but easy to overlook at this stage. Consistent with the essential oils listed in the INCI: Chamomile Oil and Geranium Oil.
Fixed amount added to a jar of warm water, shaken fifteen times. The product does not lather, it dispersed as a coating on the water rather than forming suds. No meaningful foam result.
Product applied to wet hands. Sticky and slippery without forming lather, spreads as a coating rather than foaming. An unusual texture that some users will find actively unpleasant. Rinsed from hands at normal speed.
A double dose was needed, the product stays where it is placed on the top of the head rather than distributing through the hair. A faint essential-oil note was detectable in steam. The rinse was the fastest in the test batch: a genuine positive. Post-rinse squeak was very pronounced: styrofoam-like in quality. For some users that specific friction and sound combination is its own category of difficult. No scalp discomfort during washing itself.
After drying: hair smooth and soft immediately and genuinely pleasant. Later that day and the following morning, some scalp itching developed. No lingering smell. The fast rinse and immediate soft feel are the two arguments for this product. The squeak and the itching are the two arguments against a recommendation here.
Claims checker
What the label says — what the test found
| The claim | Finding | Note |
|---|---|---|
| "Unscented / fragrance-free" | | Contains Chamomile Oil and Geranium Oil: both fragrance-active essential oils, detectable in hot water and shower use. This claim fails testing. |
| "Sulfate-free" | | Contains Sodium Laureth Sulfate (SLES) as the primary surfactant. This claim fails testing. |
| "No harsh chemicals that can upset your scalp" | | Contains SLES and CAPB, both of which can irritate sensitive scalps. Next-day itching was observed. The claim is subjective; the performance in testing does not fully support it. |
| "No artificial perfume" | | Technically accurate: the scent sources are naturally-derived essential oils rather than synthetic fragrance compounds. This is a real distinction, but a narrow one for users who react to fragrance regardless of origin. |
| "Gentle cleaning shampoo" | | The cleaning action was more aggressive than "gentle" implies: pronounced squeak and next-day itching suggest overcleaning for this scalp type. The fast rinse is a positive. "Gentle" is not supported by the overall experience. |
| "1 vitamin & 2 hair-loving ingredients" | | Pro-Vitamin B5, Chamomile Oil, and Glycerin are present in the ingredient list. The claim is accurate. |
Ingredient analysis
Key points — what bears on the sensory outcome
- Key sensory points (not a full INCI breakdown)
- Sodium Laureth Sulfate (SLES): Primary cleanser, first listed, indicating highest concentration. A sulfate; milder than SLS but still a firm cleanser. Present despite the sulfate-free claim on the front of the bottle.
- Cocamidopropyl Betaine (CAPB): Amphoteric co-surfactant. Foam booster. A documented contact allergen for some users with sensitive skin, present and worth noting for a product positioned at sensitive scalps.
- Cocamide DEA: Foam booster. Present despite the product producing almost no visible lather in testing, its effect here appears minimal.
- Sodium Chloride: Viscosity modifier. Thickens the formula; may contribute to dryness with repeated use.
- Panthenol (Pro-Vitamin B5): Humectant. Supports moisture retention and surface smoothness.
- Glycerin: Humectant. Aids moisture retention.
- Chamomile Oil (Anthemis Nobilis): Fragrance-active essential oil. Contributes the faint citrusy-floral smell detected in testing. A naturally-derived fragrance ingredient, not a synthetic compound, but still a fragrance-active ingredient that undermines the fragrance-free claim.
- Geranium Oil: Fragrance-active essential oil. Co-contributor to the detected scent. A naturally-derived fragrance ingredient with the same issue.
- Citric Acid: pH adjuster. Formula measured at approximately pH 6, a scalp-friendly range. The pleasant pH did not prevent the aggressive clean, suggesting the surfactant system is the primary driver of cleansing behaviour.
Verdict
Who this suits — and who it doesn’t
Works well if avoiding- Fastest rinse in the test batch — genuinely quick and clean
- Hair feels smooth and soft immediately after washing
- Non-lathering – a real positive for users with strong suds aversion
- Faint smell overall – the essential oils are present but not aggressive
Not right if you need- Marketed as fragrance-free – contains Chamomile Oil and Geranium Oil; this claim fails testing
- Marketed as sulfate-free – contains Sodium Laureth Sulfate; this claim also fails testing
- Very pronounced squeak – among the strongest in the batch; described in testing as styrofoam-like
- Sticky, non-lathering texture that doesn't spread – double dose required consistently
- Next-day scalp itching observed after use
- Cap squeaks; product builds up from the first use
- Small 200ml bottle at a double dose will not last long
The front of the bottle reads: fragrance-free and sulfate-free. The ingredient list contains Chamomile Oil, Geranium Oil, and Sodium Laureth Sulfate. The investigation observed these two documents simultaneously and found them difficult to reconcile.
Simple is a brand with long-standing sensitive-skin credentials. The “no artificial perfume” framing on the label is technically accurate – the scent sources are naturally-derived essential oils rather than synthetic fragrance compounds. Whether this distinction comforts users who react to fragrance regardless of origin is something the investigation declines to speculate about on their behalf.
In practice: the smell was faint and a light citrusy note – tolerable for most, but present and attributable to listed ingredients. The texture is sticky and non-spreading; a double dose was required and coverage remained uneven. The post-rinse squeak was the styrofoam variety, a specific quality of friction that the investigation records without minimising, as it is its own category of difficult. Next-day scalp itching was also noted.
The rinse was the fastest in the batch. Hair felt smooth immediately after. Both findings are recorded without irony. The label claims, however, remain what they are. For reliably odourless results: Faith In Nature. For non-lathering without the squeak: Vanicream. Smell results across all eight products are on the low-scent hub.
