Is Kérastase Genesis Bain Hydra-Fortifiant Shampoo suitable during pregnancy?

MamaSkin currently classifies Kérastase Genesis Bain Hydra-Fortifiant Shampoo as Medium risk, with a stored score of 58/100. This assessment flags concerns that need closer consideration. Review the explanation with a qualified healthcare professional before deciding whether to use this formula during pregnancy.

What does the ingredient evidence show?

The recorded formula includes 4 ingredient entries with risk flags: Sodium Laureth Sulfate (Low risk), Salicylic Acid (Low risk), Benzyl Salicylate (Medium risk), plus others listed in the breakdown. These are ingredient-level flags; they do not replace the stored product assessment or account for every formulation detail.

27 of 27 ingredient entries on this page have a recorded score, evidence summary and source text. That describes documentation coverage, not proof that the finished formula has been clinically tested during pregnancy.

Ingredients

Ingredients with a higher risk flag appear first, followed by the rest of the formula.

Benzyl Salicylate

Medium Risk

Benzyl salicylate is a fragrance ingredient that is also evaluated for potential endocrine activity and sensitisation. SCCS notes some indications for endocrine mode of action, and fragrance allergens are relevant for contact allergy risk; pregnancy-specific human outcome data for topical exposure are limited. The medium-risk signal is endocrine-related uncertainty and sensitisation potential rather than a defined pregnancy-specific toxicity dataset.

Sodium Laureth Sulfate

Low Risk

Sodium laureth sulfate (SLES) is a cleansing surfactant used mainly in rinse-off products. CIR concluded sodium and ammonium laureth sulfate safe in current cosmetics when formulations are non-irritating; skin and eye irritation is the main identified concern. The review does not identify a pregnancy-specific restriction for normal cosmetic use. MamaSkin retains Low Risk, with extra care for sensitive or damaged skin.

Sources: CIR: Final report on sodium and ammonium laureth sulfate https://pubmed.ncbi.nlm.nih.gov/20634505/

Parfum

Low Risk

Umbrella term for an undisclosed fragrance blend. It’s not usually a pregnancy-specific concern at normal cosmetic use levels, but the exact components and concentrations aren’t fully disclosed on the label, so we score it more conservatively. If you prefer maximum transparency (or you’re sensitive to fragrance compounds), choose fragrance-free/unscented products.

Salicylic Acid

Low Risk

Salicylic acid is a beta-hydroxy acid used for exfoliation and as a preservative. Exposure depends on concentration, product category, treated area, frequency, skin condition and inhalation or oral potential. Current SCCS assessments support specified cosmetic uses and restrictions; ordinary limited-area low-strength topical use is not equivalent to a professional peel, large-area leave-on treatment or oral salicylate exposure. MamaSkin retains Low Risk with those route and exposure qualifications.

Water

No Known Risks

Water (aqua) is the purified solvent used as the base of many cosmetics. MamaSkin classifies plain water as No known risks for normal topical use.

Citral

No Known Risks

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.

Xylitylglucoside

No Known Risks

A sugar-derived humectant commonly used with xylitol and anhydroxylitol to support skin hydration. Exact pregnancy-specific topical data are limited. Cosmetic safety assessments of the related saccharide mixture and xylitol did not identify a reproductive or pregnancy-specific concern at cosmetic exposure; available data primarily support local tolerance rather than proving pregnancy safety. No topical contraindication was identified in the reviewed material.

Questions about this assessment

Has every ingredient in Kérastase Genesis Bain Hydra-Fortifiant Shampoo been assessed?

27 of 27 ingredient entries on this page have a recorded score, evidence summary and source text. That describes documentation coverage, not proof that the finished formula has been clinically tested during pregnancy.

Does this assessment apply to the Kérastase Genesis Bain Hydra-Fortifiant Shampoo I have?

Only if the ingredient list on your packaging matches the recorded formula shown here. Formulas can differ by market and change over time. Compare the full list, not just the product name; report a mismatch if it differs.

Does this pregnancy assessment also establish breastfeeding suitability?

No. This page presents a pregnancy-focused product assessment. Do not infer a breastfeeding conclusion from its score or label; breastfeeding requires a separate assessment of the formula and how it is used.

How to use this assessment

The risk band is the primary conclusion. The score adds detail within that band and should not be used to compare products as if a one-point difference were clinically meaningful.

MamaSkin provides pregnancy-focused information, not medical advice. Your midwife, GP, pharmacist or dermatologist should take priority when your circumstances differ from typical cosmetic use.
