How we got 5.0 ShowHide
Methodology v3.1 (updated 8 Oct 2026) — what changed
This shampoo provides effective cleansing with a blend of mild and stronger surfactants. However, the presence of an undisclosed 'Fragrance' blend means potential allergens are not individually listed, which is a key concern for individuals with sensitive skin or fragrance allergies. While the formulation includes some conditioning agents, the beneficial ingredients like Shea Butter, Lysine HCl, and Arginine are present in trace amounts, limiting their impact. The product is generally suitable for most users, but those with known sensitivities should exercise caution due to the undisclosed fragrance and potential for irritation from Sodium Laureth Sulfate.

Shampoo with undisclosed fragrance and potential irritants
This shampoo contains Sodium Laureth Sulfate, a common surfactant that can irritate sensitive skin, and an undisclosed 'Fragrance' blend, which may contain allergens not listed individually. While it cleanses effectively, individuals with sensitive skin or fragrance allergies should be cautious. Other beneficial ingredients are present in very small amounts, limiting their overall impact.

Concern breakdown
Score out of 10 · higher = fewer concernsHow this product performs on each concern we check for haircare. This is a breakdown of the same evidence behind the score above — not a separate verdict.
Triggered by CI 19140, CI 17200 — a synthetic colour on our aromatic-amine watch list (impurity risk). A colour-quality caution, not a finding that this product contains a carcinogen.

Synthetic colorants (CI 19140, CI 17200)
PEG-45M — ethoxylated ingredient - quality depends on removal of manufacturing impurities.
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.

Sodium Benzoate: regulation, sources and other products →Sodium Laureth Sulfate
SLES is a cleansing agent that is milder than SLS but can still irritate very sensitive or compromised skin. Separately, because it is made by ethoxylation, it may carry a residue of 1,4-dioxane, which IARC classifies as possibly carcinogenic to humans (Group 2B). The ingredient list cannot show whether any is present or how much. The EU SCCS considers 1,4-dioxane at or below 10 ppm in a finished cosmetic to be safe, and manufacturers reduce it by vacuum stripping.
Regulatory & scientific authority Source: FDA; EU SCCS
Sodium Laureth Sulfate: regulation, sources and other products →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.
Regulatory & scientific authority Source: EU Regulation 1223/2009 Annex V (max 1.0%); SCCS opinion SCCS/1575/16; ANSM recommendation (2012)
Phenoxyethanol: regulation, sources and other products →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.
Regulatory & scientific authority Source: EU Regulation 2023/1545; IFRA
Fragrance: regulation, sources and other 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.
Peer-reviewed research Source: American Contact Dermatitis Society - Allergen of the Year 2004; contact-dermatitis literature
Cocamidopropyl Betaine: regulation, sources and other products →Synthetic Cosmetic Colourants (CI)
These Colour Index (CI) numbers are colourants on the EU list of permitted cosmetic colours, each with conditions on where it may be used (for example, some are allowed only in products that do not stay in contact with mucous membranes). A listed colour in a product used as directed is not a finding of harm; the colour serves only to colour the product, and this is information for anyone who prefers to avoid synthetic dyes.
Regulatory & scientific authority Source: EU Regulation 1223/2009 Annex IV (permitted colourants); SCCS opinions on colourants
Synthetic Cosmetic Colourants (CI): regulation, sources and other products →Polyethylene Glycols (PEGs)
PEG ingredients are made by ethoxylation, which can leave traces of ethylene oxide (IARC Group 1) and 1,4-dioxane (IARC Group 2B) unless removed. Good manufacturing removes them, so the ingredient itself is not a hazard, but the label cannot tell you whether it was done well. PEGs should not be applied to broken skin.
Regulatory & scientific authority Source: IARC Monographs Vol. 100F (ethylene oxide) and Vol. 71 (1,4-dioxane); Cosmetic Ingredient Review
Polyethylene Glycols (PEGs): regulation, sources and other products →Decode Label Analysis
Contains 'Fragrance', an undisclosed blend of chemicals that is a common source of allergens and sensitizers. Specific fragrance allergens are not individually listed.
Sodium Laureth Sulfate, a primary surfactant, can be irritating to sensitive skin and may carry a 1,4-dioxane impurity (IARC Group 2B, possibly carcinogenic to humans), though levels are typically controlled in finished products.
Cocamidopropyl Betaine is a recognized contact allergen, primarily due to manufacturing impurities.
Phenoxyethanol is a common preservative; French regulators advise caution for use in products for children under 3 years.
Synthetic cosmetic colorants (CI 19140, CI 17200) are present. While permitted, some individuals may have sensitivities to these.
Combined Effects interactions
Both ingredients are known irritants/sensitizers. Their combined presence may increase the overall potential for skin or scalp irritation and allergic reactions, especially in sensitive individuals.
Claim check
Front-of-pack marketing claims checked against this product's actual ingredients and nutrition. "Can't verify" means the label does not provide enough information to check the claim — it is not the same as the claim being false.
The term 'professional shampoo' is a designation that cannot be verified from the ingredient list or other label information.
The claim 'for unmanageable, frizzy hair' describes a product benefit that cannot be objectively verified from the ingredient list or other label information.
The claim '96 HOURS FRIZZ CONTROL' is a performance claim that cannot be verified from the ingredient list or other label information.
The ingredient list includes Lysine HCl and Arginine, which are amino acids, and Butyrospermum Parkii (Shea) Butter, which is shea butter.
Read straight from the back-of-pack photo — quantities, sections and any disguised terms, so the small print can’t hide behind the marketing.

About this analysis: Based on declared label information and available evidence. Decode Label does not independently laboratory-test products, and a score is not a regulatory determination or medical advice.
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.
