Kerastase Nutritive Beautifying Detangling Blow Dry Mist (5.1 oz) - Hydration, Detangling, and Heat-Proofing in a Single Mist
Skip until Kérastase discloses PFAS status; heat-proofing sprays commonly contain fluorinated water-repellents.
This spray-on styling product markets heat-protection and water resistance, two properties historically achieved with PFAS in the beauty industry. Kérastase has not publicly disclosed PFAS content or committed to eliminating them. No third-party lab testing or certifications are available to confirm either presence or absence.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 42% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
