Kérastase Première Repairing Shampoo for Damaged Hair

Sodium cocoyl isethionate is a cleansing surfactant. The Cosmetic Ingredient Review concluded that isethionate salts are safe in current cosmetic use when formulated to be non-irritating, and reviewed reproductive and developmental data did not identify a pregnancy-specific signal.

An anionic surfactant used mainly in gentle cleansers and shampoos. Cosmetic safety reviewers concluded that alkyl PEG sulfosuccinates, including disodium laureth sulfosuccinate, are safe in current practices when formulated to be non-irritating and manufactured with appropriate impurity controls.

A fatty-acid ester used for opacifying, emolliency and texture. Cosmetic safety reviewers concluded that glycol distearate is safe as used; available cosmetic exposure does not identify a pregnancy- or breastfeeding-specific concern.

An anionic surfactant used for cleansing and foam. Cosmetic safety reviewers concluded that sodium lauryl sulfoacetate is safe in current practices. It is distinct from sodium lauryl sulfate, although either surfactant can irritate sensitive skin in a strong cleanser.

An anionic cleansing surfactant. Cosmetic safety reviewers concluded that sodium lauroyl sarcosinate is safe in rinse-off cosmetics and in leave-on products up to 5%, provided it is not used in ways that promote nitrosamine formation or inhalation. No pregnancy-specific concern was identified under those conditions.

Glycerin is a widely used humectant that supports hydration and the skin barrier, with a long safety record and no known pregnancy or breastfeeding concerns in topical cosmetic use.

An ethoxylated fatty alcohol used as an emulsifier or surfactant. Cosmetic safety reviewers concluded that the assessed alkyl PEG/PPG ethers are safe in current practices when formulated to be non-irritating. Manufacturing should control ethylene oxide and 1,4-dioxane residues.

Mild nonionic surfactant used in cleansers and emulsions. Reviewed cosmetic ingredient references support normal topical rinse-off and leave-on use, with no pregnancy- or breastfeeding-specific concern identified; sensitive skin may still react to surfactants.

Mild amphoteric surfactant used in cleansers and shampoos to boost foam and reduce harshness. Reviewed cosmetic safety sources support present cosmetic use, with no pregnancy- or breastfeeding-specific topical signal identified; the main practical caveat is irritation or allergy in some users, sometimes linked to sensitising impurities.

A cleansing and foam-supporting surfactant made from coconut-derived fatty chains. Cosmetic safety reviewers concluded that alkyl betaines, including coco-betaine, are safe in current practices when formulated to be non-irritating. Surfactant-containing products may still sting eyes or irritated skin.

pH adjuster used in small amounts to maintain product stability. Not associated with pregnancy-specific concerns.

pH adjuster used in very small quantities to balance formulations. Not associated with pregnancy-specific concerns.

A large conditioning and film-forming polymer used mainly in hair and cleansing products. Cosmetic safety reviewers concluded that Polyquaternium-7 is safe in current cosmetic use at the reviewed concentrations. Its polymeric nature limits systemic exposure, and no pregnancy-specific concern is identified for normal topical use.

A large cationic cellulose polymer used to condition hair and improve product texture. Cosmetic safety reviewers concluded that Polyquaternium-10 is safe in current cosmetic use; human testing did not indicate irritation or sensitization at reviewed concentrations. No pregnancy-specific concern is identified for normal topical exposure.

Polymer thickener used to create gel textures. Large-molecule ingredient with negligible systemic absorption.

Preservative widely used in foods and cosmetics. Considered safe at regulated concentrations with low systemic exposure from topical use.

Sodium chloride is used to adjust viscosity and texture in formulations; topical cosmetic use is considered low concern with no known pregnancy or breastfeeding risks.

Limonene is a common fragrance component used at low levels in cosmetics; it is not a pregnancy-specific concern in topical use, but it is a recognised fragrance allergen and may trigger irritation or sensitisation in some people, especially if the product oxidises over time.

Propylene glycol is a common solvent and humectant with a long history of use; it is not considered a pregnancy or breastfeeding concern in topical cosmetics, though some individuals may experience irritation in leave-on products.

Preservative acid used to help control microbial growth and support formula stability. Reviewed cosmetic safety sources support current cosmetic use, with no pregnancy- or breastfeeding-specific topical concern identified in the material reviewed; some users may still notice local irritation or stinging, especially on compromised skin.

A hydrolysed plant-protein derivative coupled to a silanetriol group and used mainly for hair conditioning and strengthening. Systemic exposure is expected to be low in rinse-off and hair products. No pregnancy- or reproductive-toxicity signal was identified for normal cosmetic exposure; people with sensitivity to the source protein may still react locally.

Amino acid used as a humectant and skin/hair-conditioning support ingredient. Reviewed cosmetic safety sources support normal topical use, with no pregnancy- or breastfeeding-specific topical signal identified.

An ethoxylated fatty alcohol used mainly as an emulsifier, surfactant or solubiliser. Cosmetic safety reviewers concluded that alkyl PEG/PPG ethers are safe in current practices when formulated to be non-irritating. Manufacturing controls should limit residual ethylene oxide and 1,4-dioxane.

Linalool is a common fragrance component used at low levels in cosmetics; it is not a pregnancy-specific concern in topical use, but it is a recognised fragrance allergen and may trigger irritation or sensitisation in some people, especially if the product oxidises over time.

A lemon-scented mixture of the aldehydes geranial and neral used in fragrance. Citral is a recognised skin sensitiser, but current cosmetic concerns relate to allergy and concentration rather than a pregnancy-specific hazard from normal topical use.
