Is it suitable during pregnancy?
MamaSkin rates the recorded formula for Kérastase Première Repairing Shampoo for Damaged Hair as Low risk (72/100). Review the ingredient context and any manual-review explanation before deciding.
Why this rating?
The recorded formula includes 4 ingredient entries with risk flags: Parfum/Fragrance (Low risk), Amodimethicone (Low risk), Salicylic Acid (Low 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.
36 of 37 ingredient entries on this page have a recorded score, evidence summary and source text. 1 entry does not have all of those fields. Unmatched or unrated entries are marked Not assessed in grey; missing evidence does not establish safety.

Ingredient ratings and evidence
Higher-risk flags first. Open an ingredient for evidence.
Parfum/Fragrance
Low risk
An exact label variant for an undisclosed fragrance blend. Fragrance is not usually a pregnancy-specific concern at normal cosmetic levels, but the precise components and concentrations are not fully disclosed, so MamaSkin scores the umbrella term conservatively. People sensitive to fragrance may prefer fragrance-free products.

Phenoxyethanol
Low risk
Phenoxyethanol is a preservative permitted in EU cosmetics up to 1.0%. The SCCS concluded it is safe for cosmetic use at that level, including when considering higher cosmetic exposure scenarios in infants and young children. Main practical concern is irritation/stinging on very sensitive or compromised skin rather than a pregnancy- or breastfeeding-specific risk.
Sources: SCCS/1575/16: Phenoxyethanol opinion https://health.ec.europa.eu/publications/phenoxyethanol_en
Amodimethicone
Low risk
This ingredient is a silicone polymer included in CIR's dimethicone, methicone and substituted-methicone family assessment. CIR concluded the reviewed ingredients safe as used when formulated to be non-irritating to skin and eyes. This is family-level cosmetic evidence, not ingredient-specific human pregnancy evidence for every derivative. MamaSkin therefore retains Low Risk without claiming negligible absorption for this individual ingredient.

Salicylic Acid
Low risk
Salicylic acid is a beta-hydroxy acid (BHA) used for acne, exfoliation and preservation. Common over-the-counter acne strengths are 0.5-2%, including 0.5%, 1% and 2%; the FDA lists this acne-treatment range. Pregnancy guidance distinguishes these topical products from oral salicylates and strong peels. MotherToBaby reports that ACOG allows over-the-counter topical salicylic acid during pregnancy when needed. Only a small amount of topical acne treatment usually reaches the bloodstream through intact skin; exposure can increase with damaged skin, frequent use or treatment of large areas. Direct salicylic-acid-specific pregnancy data remain limited. MamaSkin's Low Risk rating is a dose-and-use precaution, not evidence that ordinary low-strength skincare causes fetal harm or a recommendation to avoid every BHA product. Use as directed on limited areas of intact skin. Discuss strengths above 2%, chemical peels, wart/corn removers, large-area treatment or use under occlusion with your clinician before use during pregnancy. The American Academy of Dermatology specifically advises discussing and limiting higher-strength salicylic acid above 2%. Percentage alone does not establish safety: formulation, area, frequency and skin condition also matter. General cosmetic-use limits are not pregnancy-specific safety thresholds.

Cocamidopropyl Betaine
No known risks
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.

Coco-Betaine
No known risks
A cleansing and foam-supporting surfactant made from coconut-derived fatty chains.

Questions about this assessment
Why does Kérastase Première Repairing Shampoo for Damaged Hair have a Low risk rating?
The recorded formula includes 4 ingredient entries with risk flags: Parfum/Fragrance (Low risk), Amodimethicone (Low risk), Salicylic Acid (Low 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. Incomplete ingredient documentation does not establish safety; see the coverage answer and grey entries below.
Has every ingredient in Kérastase Première Repairing Shampoo for Damaged Hair been assessed?
36 of 37 ingredient entries on this page have a recorded score, evidence summary and source text. 1 entry does not have all of those fields. Unmatched or unrated entries are marked Not assessed in grey; missing evidence does not establish safety.
Does this assessment apply to my Kérastase Première Repairing Shampoo for Damaged Hair?
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.
