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 contradict the front label, and in a hot shower you can smell them.
Tested in hard water (South Downs UK). Single-blind. No conditioner used in shower test.

Sensory scorecard
This review examines two dimensions: smell and texture & behaviour.
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.
The shampoo texture is the most difficult aspect of this product in use. The gel is sticky and did not spread easily. A normal quantity covered only the top of the head. A double dose was consistently required, and spreadability remained poor. The squeaky feeling under hands after rinsing was intense like styrofoam: not merely clean-feeling but a specific quality of friction that constitutes its own category of sensory difficulty. The cap also has a triggering squeak and collects product residue from the first use. The fast rinse time is one aspect which is worth recommending.
Case notes
Simple is a drugstore staple and is widely available. The brand has built its reputation on a sensitive-skin positioning consistent, claiming no unnecessary ingredients, no harsh chemicals, and designed for reactive skin. Simple’s label has claims which are not fully supported.
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 ingredients list. The brand’s “no artificial perfume” framing is technically accurate because both oils are naturally derived. The front reads sulfate-free however Sodium Laureth Sulfate is the first listed surfactant.
The bottle says sulfate-free on the front. It isn’t. Sodium Laureth Sulfate sits in the ingredient list, and whether you spell it sulfate or sulphate the answer is the same: this is an SLES-based cleanser marketed as though it weren’t. The claim isn’t a lie about what’s inside, because the ingredients are printed accurately on the back. It’s a front-of-pack claim that contradicts them, and for anyone avoiding sulphates on a reactive scalp that distinction matters more than the chemistry does.
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 does not seem to be in line with the “gentle” branding. CAPB is also 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 a better alternative. For non-lathering shampoo, if you are avoiding foam, 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

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.

Leaves residue on the cap from the first use.
Medium-thick, slightly gooey gel but crystal clear.

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.
A fixed amount was added to a jar of warm water, shaken fifteen times. The product dispersed as a coating on the water rather than forming suds. No meaningful foam result.
Product applied to wet hands. It was slightly stringy and sticky. Shampoo became slippery without forming lather, spreading 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 because without lathering, the product clings to 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 although tolerable and not unpleasant. The rinse was the fastest in the test batch: a genuine positive. Post-rinse squeak under hands was very pronounced. For some users, that specific friction and sound combination is very difficult. No scalp discomfort noted during washing itself.
After drying: hair was left smooth and soft immediately which was a pleasant surprise. 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
| 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

Verdict
The front of the bottle reads: fragrance-free and sulfate-free. The ingredient list contains Chamomile Oil, Geranium Oil, and Sodium Laureth Sulfate.
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 another matter.
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, an intense and often triggering squeak in the hands. Next-day scalp itching was also noted.
The rinse was the fastest in the batch. Hair felt smooth immediately after. 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. For a full sensitivity cross-reference across all eight products, see the ingredient sensitivity guide.
