Decode Label Safety Score
How we got 5.0 ShowHide
Reviewed 10 times · Methodology v3.1 (updated 8 Oct 2026) — what changed
This shampoo contains Sodium Laureth Sulfate, a primary surfactant that can be irritating for some individuals, particularly those with sensitive scalps. The presence of 'Fragrance' along with several disclosed fragrance allergens like Limonene, Linalool, and Hexyl Cinnamal, indicates a high potential for sensitisation for those with fragrance allergies or contact dermatitis. While it offers conditioning agents, the overall formulation prioritizes cleansing and lather, which may not be ideal for very dry or sensitive hair types.

Contains irritating surfactant and multiple fragrance allergens; not for sensitive skin.
This shampoo uses Sodium Laureth Sulfate, a common cleansing agent that can cause irritation for sensitive skin or scalps. It also includes an undisclosed 'Fragrance' blend alongside several known fragrance allergens, increasing the risk of allergic reactions for susceptible individuals. While it cleanses effectively, those with sensitivities should approach with caution.

What's good
Includes multiple conditioning agents (Guar Hydroxypropyltrimonium Chloride, Dimethicone, Amodimethicone) to help detangle and smooth hair.
Contains mild co-surfactants (Cocamidopropyl Betaine, Coco-Betaine) to balance the cleansing action.
Includes Salicylic Acid and Glycolic Acid, which can be beneficial for scalp health and exfoliation.
Watch out for
High potential for fragrance-related irritation or allergic reactions due to undisclosed 'Fragrance' and multiple listed allergens.
Sodium Laureth Sulfate can be irritating for sensitive scalps.
Silicones (Dimethicone, Amodimethicone) may lead to build-up on hair over time for some users, requiring clarifying shampoos.
Ingredient Concerns safety database
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.
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.

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 →Decode Label Analysis
Contains 'Fragrance' (Parfum) which is an undisclosed blend of chemicals, a common source of skin irritation and allergic reactions. This product also explicitly lists several known fragrance allergens (Hydroxycitronellal, Limonene, Linalool, Hexyl Cinnamal) which are part of the EU-26 list of substances most frequently associated with contact allergy.
Sodium Laureth Sulfate (SLES) is a primary surfactant that can be irritating to the skin and scalp, particularly for individuals with sensitive skin or conditions like eczema. While milder than SLS, it can still strip natural oils and cause dryness or irritation.
Combined Effects interactions
Cocamidopropyl Betaine and Coco-Betaine are often used to mitigate the potential irritation of stronger anionic surfactants like Sodium Laureth Sulfate, creating a milder overall cleansing system.
The combination of an undisclosed 'Fragrance' blend with multiple individually declared fragrance allergens significantly increases the overall potential for allergic reactions and skin sensitization, especially for individuals with fragrance sensitivities.
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.
Present in trace amounts
Listed near the end of the ingredient list, so present in small quantities — not counted as a headline benefit.

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.
