Frizz Ease Miraculous Recovery Shampoo — ingredient safety report

• Hormone disruption:Classified as toxic to reproduction (CMR 1B); banned in the EU since March 2022.
• Allergy risk:Well-documented fragrance sensitizer.

The lily-of-the-valley scent 'Lilial', banned in EU cosmetics in 2022 after being classified as presumed toxic to human reproduction. Still legal in some other markets — check older or imported products.

• Cancer concern:Slowly releases formaldehyde, an IARC Group 1 carcinogen.
• Allergy risk:Frequent cause of preservative contact dermatitis.

A formaldehyde-releasing preservative used in creams, shampoos and wipes. The slow formaldehyde release preserves the product but exposes skin to a known carcinogen and allergen.

• Allergy risk:Fragrance is the single most common cause of cosmetic contact allergy.
• Irritation:Frequent trigger of stinging and redness on reactive skin.

An umbrella term that can hide dozens of undisclosed scent chemicals. Fragrance is the leading cause of allergic contact dermatitis from cosmetics, and dermatologists routinely advise fragrance-free products for eczema, babies and sensitive skin.

• Irritation:Milder than SLS but still drying for compromised skin.

The gentler cousin of SLS used in most mainstream shampoos and washes. Its manufacturing can leave trace 1,4-dioxane, which reputable makers strip out — an issue of quality control rather than the ingredient itself.

• Pore-clogging:Rates high on comedogenicity scales.

An emulsifier that scores relatively high for pore-clogging potential in classic comedogenicity testing.

• Allergy risk:EU-declarable allergen; oxidized linalool is a common patch-test positive.

A floral scent molecule found in lavender and many essential oils. It oxidizes on air exposure into strongly sensitizing compounds, which is why it must be declared on EU labels.

• Allergy risk:EU-declarable allergen; oxidation products are potent sensitizers.

The citrus-peel scent molecule. Like linalool, it becomes allergenic mainly after oxidizing in opened products.

• Allergy risk:Named Allergen of the Year 2004; impurities (amidoamine) drive most reactions.

A mild coconut-derived surfactant in countless 'gentle' cleansers. Most allergy is caused by manufacturing impurities, so quality varies by brand.

• Allergy risk:One of the 26 EU-declarable fragrance allergens.
• Irritation:Mild irritation possible at higher concentrations.

A preservative and fragrance component that must be declared on EU labels because it can trigger contact allergy in a small share of users.

• Allergy risk:EU-declarable fragrance allergen.

A common jasmine-scented ingredient in fine fragrance and skincare, declared as an allergen on EU labels.

A longer-chain paraben with measurable (though weak) estrogenic activity, prompting the EU to reduce its allowed concentration and Denmark to ban it in products for children under 3.

• Environmental impact:Not biodegradable; accumulates in the environment via wash-off.

The workhorse silicone — inert and non-sensitizing on skin (even FDA-approved as a skin protectant), with persistence in the environment as its main criticism.

• Environmental impact:Poorly biodegradable; can remobilize heavy metals in waterways.

A metal-binding stabilizer that is safe on skin at the tiny amounts used; its criticism is environmental persistence.
