Methodology v3.1 (updated 8 Oct 2026) — what changed
This hair serum offers conditioning benefits primarily from silicones and a cationic polymer, which can help smooth hair and reduce frizz. However, the presence of undisclosed 'Fragrance' is a significant concern for individuals with sensitive skin or fragrance allergies, as it can contain numerous potential allergens not individually listed. While ingredients like Argania Spinosa Kernel Oil, Panthenol, and Tocopheryl Acetate are listed, their trace amounts mean they are not counted as a formulation strength overall efficacy or benefits. The product also contains synthetic colorants and a preservative (Phenoxyethanol) that some consumers may prefer to avoid.

Hair serum with silicones and undisclosed fragrance; trace beneficial oils
This hair serum uses silicones and conditioning agents to smooth hair, but it contains an undisclosed 'Fragrance' blend, which is a common source of allergens for people with sensitive skin or fragrance allergies. While some beneficial oils and vitamins are listed, they are not counted as a formulation strength. It also includes synthetic colorants and a preservative that some users may wish to avoid.

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 42090 — a synthetic colour on our aromatic-amine watch list (impurity risk). A colour-quality caution, not a finding that this product contains a carcinogen.

Watch out for
Undisclosed 'Fragrance' can be a source of allergens for sensitive individuals
Contains synthetic colorants (CI 19140, CI 42090)
Phenoxyethanol is a preservative some consumers prefer to avoid, especially for young children
Beneficial ingredients like Argania Spinosa Kernel Oil, Panthenol, and Tocopheryl Acetate are present only in trace amounts
Propylene Glycol Dicaprylate/Dicaprate — humectant/solvent - occasional skin irritant at higher concentration.
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 →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 →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 →Propylene Glycol (E1520)
Propylene glycol is a widely used humectant and solvent considered safe at normal levels. It can irritate or sensitise a minority of people, mainly in leave-on products on damaged or eczema-prone skin.
Peer-reviewed research Source: Cosmetic Ingredient Review; contact-dermatitis literature
Propylene Glycol: regulation, sources and other products →Decode Label Analysis
Contains 'Fragrance' without specific disclosure of individual fragrance allergens, which are common sensitizers for individuals with sensitive skin or fragrance allergies. EU regulations require specific declaration of known allergens above certain thresholds.
Contains ethoxylated ingredients (PPG-1 Trideceth-6, PEG-40 Hydrogenated Castor Oil) which may carry trace amounts of 1,4-dioxane, a manufacturing impurity classified by IARC as Group 2B (possibly carcinogenic to humans). The EU SCCS considers 1,4-dioxane at or below 10 ppm in finished cosmetics safe.
Contains Phenoxyethanol, a preservative. The French regulator advises caution for use in products for children under 3 years old.
Claim check

Polyglutamic Acid is not listed in the ingredients.
The claim of '17X weightless hydration' is a performance claim that cannot be verified from the ingredient list.
The claim of '100H frizz control' is a performance claim that cannot be verified from the ingredient list.
The term 'Professional Serum' is a product designation and cannot be verified from the ingredient list.

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.
