Methodology v3.1 (updated 8 Oct 2026) — what changed

This shampoo offers a gentle cleansing experience with mild surfactants, making it suitable for most hair types. However, the presence of undisclosed 'Fragrance' is a notable concern for individuals with sensitive skin or fragrance allergies, as it can contain various unlisted allergens. While several botanical extracts and oils are included, their trace amounts mean they are not counted as a formulation strength. Overall, it's a well-formulated rinse-off product for general use, but those with fragrance sensitivities should exercise caution.

Gentle shampoo with mild surfactants, but contains undisclosed fragrance

This shampoo uses a mild surfactant system that is generally well-tolerated, making it suitable for daily use. The main concern is the inclusion of 'Fragrance' without specific disclosure of its components, which can be problematic for people with sensitive skin or fragrance allergies due to potential hidden allergens. Several botanical ingredients are present but in very small amounts, so their benefits are likely minimal.

Okay for: Most adults without fragrance sensitivities

Why the score is capped

Undisclosed fragrance (allergens not named)

Rule PC-CAP-06

What's good

Uses a blend of mild surfactants (Sodium Lauroyl Sarcosinate, Caprylyl/Capryl Glucoside, Sodium Methyl Cocoyl Taurate) which are less irritating than harsh sulfates.

Contains multiple conditioning agents (Cetrimonium Chloride, Guar Hydroxypropyltrimonium Chloride, Polyquaternium-10) to help detangle and smooth hair.

Includes humectants like Glycerin and Sodium PCA for hydration.

Watch out for

The presence of 'Fragrance' without specific allergen disclosure is a significant transparency concern and a potential irritant for sensitive individuals.

Phenoxyethanol is present as a preservative, with regulatory caution advised for young children.

Cocamidopropyl Betaine can be a contact allergen for some users due to impurities.

Several botanical extracts and oils are listed but appear in trace amounts, suggesting minimal functional benefit to the formulation.

Disodium EDTA — disodium EDTA is a chelating agent that keeps a product stable and clear. It has been flagged in some studies for potential endocrine-disrupting properties; regulatory consensus is not yet established, so it is noted as a low-level concern rather than a confirmed hazard.

Sodium Benzoate (E211)

Benzoates are permitted preservatives with an established acceptable daily intake. Two documented concerns: in acidic drinks that also contain ascorbic acid (vitamin C) they can slowly form small amounts of benzene, especially with heat and light (US FDA beverage survey, 2006); and sodium benzoate was one of the additives in the Southampton study mixtures associated with hyperactivity in children. It can also trigger reactions in some people with asthma or urticaria.

Phenoxyethanol

Phenoxyethanol is the most widely used paraben-free preservative. The EU limits it to 1% in cosmetics (SCCS has confirmed this is safe for adults), and the French regulator ANSM advised in 2012 against leave-on products containing it for the nappy area of children under three and recommended a lower concentration for them. It can irritate sensitive skin.

Fragrance

"Fragrance" or "parfum" is a catch-all term that can conceal a blend of hundreds of undisclosed chemicals, including known allergens, sensitisers, and potential endocrine disruptors. The EU now mandates disclosure of 82 specific fragrance allergens. People with fragrance sensitivity, asthma, or contact dermatitis should prefer fragrance-free products.

Cocamidopropyl Betaine

Cocamidopropyl betaine is the usual "gentle" co-surfactant in shampoos, face washes and baby washes. It was named Allergen of the Year by the American Contact Dermatitis Society in 2004; the reactions are attributed mainly to impurities (amidoamine, DMAPA) and are uncommon, but it is a common cause of surfactant allergy in people with eczema.

Decode Label Analysis

Contains 'Fragrance' (Parfum), an undisclosed blend of chemicals that is a common source of allergens and sensitizers. Individuals with sensitive skin or fragrance allergies should exercise caution. EU regulations require specific declaration of certain fragrance allergens above a threshold, which is not met by a generic 'Fragrance' listing.

Phenoxyethanol is present as a preservative. While generally safe at permitted concentrations (capped at 1%), the French regulatory body advises caution for use in products intended for children under 3 years old.

Cocamidopropyl Betaine, a mild surfactant, is a recognized contact allergen for some individuals, primarily due to manufacturing impurities.

Combined Effects interactions

Sodium Benzoate Fragrance

While Sodium Benzoate can form benzene in the presence of Vitamin C, this product does not list Vitamin C. However, both Sodium Benzoate and undisclosed 'Fragrance' are potential sensitizers, which could cumulatively increase the risk of irritation or allergic reaction for highly sensitive individuals, especially given the lack of transparency for 'Fragrance'.

Claim check

Trace amounts: some named ingredients appear in token quantities or low in the list. At these concentrations a meaningful benefit is unlikely, and their front-of-pack prominence may not reflect their level in the formulation.

In label order — normally largest quantity first. Select a row for the full write-up and sources.

Fragrance allergens are substances EU cosmetics rules require to be named on the label (such as Limonene and Linalool). Fragrant botanicals such as essential oils are grouped with them because they can naturally contain such substances, but they are not on that list. They matter mainly for people with fragrance allergies or already-sensitive skin — not a general-population safety issue. Each named allergen takes a small deduction from the ingredient score, and a high count can cap it; fragrant botanicals take none. Naming them on the label is a transparency positive.

Disclaimer: Safety scores are Decode Label-generated assessments based on publicly available regulatory data (FSSAI, WHO, EFSA, IARC) and peer-reviewed research. They are not a substitute for professional medical advice, and they are not a regulatory determination, a laboratory safety certification or a medical diagnosis. Ingredient safety can vary by individual health conditions, concentration, and usage context. Decode Label is an independent information service and scores every brand by the same rules. No brand pays for or influences its score. Our founder also founded the personal-care brand Botani Bestie (see our story); its products are scored exactly like everyone else's. Data limitations: This assessment is based on the information declared on the product label and the evidence sources above — Decode Label does not independently laboratory-test this product. Ingredient concentrations, sourcing and manufacturing can vary between batches and are not always disclosed. A finding that is not shown here means it was not identified from the available label information, not that it has been ruled out.
