Decode Label Safety Score
How we got 2.5 ShowHide
Methodology v3.1 (updated 8 Oct 2026) — what changed
The score is capped for a specific safety reason, set out below. This shampoo contains several ingredients of concern, most notably DMDM Hydantoin and Methylchloroisothiazolinone/Methylisothiazolinone (MCI/MI), both formaldehyde-releasing preservatives and potent contact sensitizers. While these are permitted in rinse-off products at restricted concentrations, their presence is a significant concern for individuals with sensitive skin or known allergies to these compounds. The undisclosed 'Fragrance' also presents a risk for those with fragrance sensitivities, as specific allergens are not listed. The primary surfactant, Sodium Laureth Sulfate, can be irritating to sensitive skin and may contain trace amounts of 1,4-dioxane (a manufacturing by-product that IARC classifies as possibly carcinogenic, Group 2B), though levels are typically regulated to be safe in finished products. Given these factors, individuals with sensitive skin, allergies, or those seeking to avoid formaldehyde-releasing preservatives and undisclosed fragrances should exercise caution.

- Guar Hydroxypropyltrimonium Chloride
Contains formaldehyde-releasing preservatives and undisclosed fragrance
The score is capped for a specific safety reason, set out below. This shampoo includes DMDM Hydantoin and Methylchloroisothiazolinone/Methylisothiazolinone, preservatives known to release formaldehyde and cause skin sensitization. It also contains an undisclosed 'Fragrance' blend, which can be problematic for people with fragrance allergies. The main cleansing agent, Sodium Laureth Sulfate, may irritate sensitive skin and could contain a trace impurity called 1,4-dioxane, which is a possible carcinogen.

Watch out for
Presence of multiple potent sensitizing preservatives (DMDM Hydantoin, Methylchloroisothiazolinone, Methylisothiazolinone) increases risk of allergic reactions.
Undisclosed 'Fragrance' can trigger sensitivities in allergic individuals.
Sodium Laureth Sulfate may cause skin irritation, especially for sensitive skin.
Dimethiconol, a silicone, can lead to product build-up on hair over time.
CI 19140 — permitted cosmetic colourant - the EU limits where on the body each may be used.
CI 17200 — permitted cosmetic colourant - the EU limits where on the body each may be used.
CI 42090 — permitted cosmetic colourant - the EU limits where on the body each may be used.
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.

Sources cited below may be Indian (FSSAI) or international (EU, US, WHO, IARC) — an international classification or law is evidence, not an Indian regulatory finding.
Methylisothiazolinone
MI and its chlorinated partner MCI are preservatives and recognised contact sensitisers. After MI replaced parabens in many products, European dermatology clinics recorded a sharp rise in contact allergy to it. Contact allergy, once acquired, is usually long-lasting, so people already sensitised to MI are advised to avoid it. EU rules ban MI from leave-on cosmetics (since 2017) and limit it to 15 ppm in rinse-off products. Whether a particular product causes a reaction depends on the person, the concentration and the contact time, which the label alone cannot show.
Regulatory & scientific authority Source: EU Regulation 2017/1224; SCCS Opinion SCCS/1521/13; British Journal of Dermatology (MI epidemic)
Methylisothiazolinone: regulation, sources and other products →DMDM Hydantoin
DMDM hydantoin slowly releases formaldehyde as a preservative mechanism. Formaldehyde is a known carcinogen (IARC Group 1) and potent sensitiser. It can cause allergic contact dermatitis. The EU restricts its maximum concentration and requires labelling that it releases formaldehyde.
Regulatory & scientific authority Source: IARC; EU Cosmetics Regulation Annex V
DMDM Hydantoin: 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 →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 →Decode Label Analysis
Contains DMDM Hydantoin, a formaldehyde-releasing preservative with carcinogen concerns related to formaldehyde release (EU Reg. 2022/1181).
Contains Methylchloroisothiazolinone and Methylisothiazolinone, potent contact sensitizers prohibited in EU leave-on cosmetics and restricted in rinse-off products (EU Reg. 2016/1198).
Contains Sodium Laureth Sulfate, a primary surfactant that can irritate sensitive skin and may carry a 1,4-dioxane impurity (IARC Group 2B, possibly carcinogenic to humans), though EU SCCS considers ≤10 ppm safe in finished products.
Contains undisclosed 'Fragrance', a common source of allergens, raising transparency concerns as specific allergens are not named (EU Reg. 1223/2009).
Contains Cocamidopropyl Betaine, a mild surfactant but a recognized contact allergen, mostly due to manufacturing impurities.
Combined Effects interactions
The combination of multiple potent sensitizing preservatives (formaldehyde-releasing and isothiazolinones) increases the overall risk of contact sensitization and allergic reactions, especially for individuals already prone to skin sensitivities.
Claim check
1 claim not supported by label dataFront-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 claim of 'UP TO 98% LESS HAIR BREAKAGE*' is a performance claim that requires external testing or clinical data to substantiate, which is not available on the ingredient list.
The term 'Keratin Fillers' is a proprietary or marketing term and cannot be directly matched to a specific ingredient in the provided list, nor is keratin explicitly listed.
The designation 'PROFESSIONAL SHAMPOO' is a product classification or marketing term that 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.
