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

This shampoo uses Ammonium Lauryl Sulfate, a harsh primary surfactant known for its potential to strip the skin barrier, which may be irritating for individuals with sensitive scalps. While it contains beneficial ingredients like Niacinamide and Salicylic Acid, the presence of 'Fragrance' and multiple declared fragrance allergens (Limonene, Hexyl Cinnamal, Coumarin, Benzyl Alcohol, Linalool, Amyl Cinnamal) means it carries a high sensitisation risk for those with fragrance allergies or contact dermatitis. The formulation also includes Cocamidopropyl Betaine, a mild surfactant that can still be a contact allergen due to manufacturing impurities. Overall, it is a functional rinse-off shampoo, but those with sensitive skin or fragrance sensitivities should exercise caution.

Harsh surfactant and high fragrance allergen load for sensitive scalps

This shampoo contains Ammonium Lauryl Sulfate, a strong cleansing agent that can be irritating and strip the scalp's natural oils, similar to SLS. It also includes 'Fragrance' and several individually declared fragrance allergens, which increases the risk of allergic reactions for people with sensitive skin or fragrance allergies. While it has some beneficial ingredients like Niacinamide, the primary concerns are related to potential irritation and sensitisation from its cleansing system and fragrance components.

Ammonium Lauryl Sulfate

ALS is the ammonium salt of lauryl sulfate and behaves much as SLS does: a powerful anionic detergent that lifts oils aggressively and can leave the skin barrier disrupted, tight and reactive. It is a common primary cleanser in cheaper shampoos and body washes. Those with eczema, rosacea or already-sensitised skin do better with a syndet or amino-acid surfactant system.

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.

Fragrance Allergens (EU-listed)

These are individual fragrance components that are known contact allergens. EU rules require them to be named on the label when present above 0.001% (leave-on) or 0.01% (rinse-off), because "parfum" alone would hide them. Limonene and linalool are especially common and become more allergenic as they oxidise on exposure to air. This is a risk for people who are sensitised, not a general-population hazard.

Salicylic Acid

Salicylic acid is a keratolytic acne and dandruff active. EU rules cap it (3% in leave-on products) and bar it from leave-on products for children under three years except shampoos, because it is absorbed through the skin and is chemically related to aspirin. Dermatologists commonly advise limiting high-strength use in pregnancy.

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.

Benzyl Alcohol

Benzyl alcohol is both a preservative (permitted up to 1% in the EU) and one of the fragrance substances the EU requires to be named on a label because it can cause contact allergy in sensitised people. It is information for someone who knows they react to it, not a general hazard.

Decode Label Analysis

Contains Ammonium Lauryl Sulfate, a harsh primary surfactant known for its potential to strip the skin barrier and cause irritation, especially for sensitive skin. This is a significant concern for a rinse-off product.

Contains 'Fragrance' (undisclosed blend) and multiple declared fragrance allergens (Limonene, Hexyl Cinnamal, Coumarin, Benzyl Alcohol, Linalool, Amyl Cinnamal). This high load of fragrance components increases the risk of sensitisation and allergic reactions for individuals with sensitive skin or fragrance allergies.

Contains Cocamidopropyl Betaine, a mild surfactant that is a recognised contact allergen, primarily due to manufacturing impurities.

Contains Salicylic Acid, an exfoliating active. While generally safe in rinse-off products, it is not recommended for leave-on use on children under 3 and should be used with caution during pregnancy.

Combined Effects interactions

Sodium Benzoate Citric Acid

While less of a concern in rinse-off products, the combination of Sodium Benzoate and Citric Acid (a source of Vitamin C) can potentially form benzene, a known carcinogen. However, this interaction is highly dependent on concentration, pH, and temperature, and is generally mitigated in cosmetic formulations, especially rinse-off ones.

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.

?
"6 micrograms per 100 ml" Can't verify

The label states '6 micrograms per 100 ml' but does not specify which ingredient this concentration refers to, making it unverifiable.

?
"BREAKING, FALLING HAIR" Can't verify

The claim 'BREAKING, FALLING HAIR' describes a hair concern the product aims to address, but it is a benefit claim that cannot be verified from the ingredient list alone.

✓
"FORTIFYING CONCENTRATE with rosemary oil + niacinamide" Checks out

The ingredient list includes 'ROSMARINUS OFFICINALIS LEAF OIL / ROSEMARY LEAF OIL' and 'NIACINAMIDE', confirming the presence of both ingredients.

ROSMARINUS OFFICINALIS LEAF OIL / ROSEMARY LEAF OIL NIACINAMIDE

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.
