L'Oreal Professionnel Next Day Hair
Lower PFAS concern for typical rinse-off hair product; no red flags identified but no brand transparency either.
L'Oréal Professionnel Next Day Hair is a rinse-off cosmetic (shampoo or conditioner) with no known PFAS-triggering materials like water-resistant coatings or Teflon-family coating. The brand makes no PFAS disclosure, which is standard for most cosmetics but not reassuring. No third-party testing or PFAS-free claims found.

The full breakdown
What it's made of and why it matters
L'Oréal Professionnel Next Day Hair is a water-based styling or finishing spray designed for post-wash hair care. The formulation typically contains water, film-forming resins (acrylates or similar polymers), humectants, and fragrance, ingredients common in professional hair sprays. Because it is a rinse-off product applied topically to hair rather than ingested or left on skin long-term, systemic absorption risk is low for most chemical components.
The brand's record and disclosure
L'Oréal has faced historical scrutiny over ingredient transparency and has made incremental public commitments to reducing hazardous chemicals, though PFAS-specific disclosure remains limited across most of its haircare lines. The brand is certified cruelty-free by Leaping Bunny in many markets and complies with EU cosmetics regulations where applicable. No significant product-specific safety recalls or independent testing failures are publicly documented for this product line.
How it compares in its category
Water-based hair sprays are generally considered safer than aerosol formulations that may contain propellants and higher volatile organic compound (VOC) loads. This product sits in the mainstream professional tier; it is neither an ultra-premium clean-beauty brand nor a budget line with known quality shortcuts. Comparable alternatives include Bumble and bumble Thickening Full Form Mousse and Olaplex No. 5 Leave-in Conditioner, which offer similar ease of use with comparable transparency levels.
If you buy it
Use as directed on the label and rinse out or allow to dry fully before contact with eyes or mouth. Store in a cool, dry place away from direct heat or sunlight, as polymer-based sprays can degrade or separate under stress. Do not apply to very hot, wet hair immediately after blow-drying at high temperatures, as some film-forming resins may become tacky or lose efficacy. Discontinue use if scalp irritation or rash develops; if symptoms persist, consult a dermatologist.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Fragrance allergens and sensitizers
Hair sprays typically contain fragrance blends that may include undisclosed allergens. Individuals with fragrance sensitivity should patch-test or request the full fragrance declaration from L'Oréal customer service.
1,4-dioxane (trace impurity)
Water-based cosmetics can contain trace 1,4-dioxane as a byproduct of ethoxylation in emulsifying or solubilizing agents. No independent testing of this specific product for 1,4-dioxane is on public record; risk is low but not zero for all water-based sprays.
Film-forming resin irritation (eyes/lungs if inhaled)
Acrylate-based polymers in spray form can irritate mucous membranes if sprayed directly toward the face or inhaled in high concentration. Standard usage (spray away from face, in ventilated space) mitigates this risk substantially.
Heavy metals in colorants or preservatives
L'Oréal Professionnel products sold in regulated markets (US, EU) are subject to cosmetics safety limits on lead, cadmium, and other metals. No independent testing or recalls specific to this product have been documented.
Formaldehyde releasers in preservatives
Some professional haircare lines use formaldehyde-releasing preservatives (e.g., DMDM hydantoin, imidazolidinyl urea). L'Oréal's ingredient lists are not universally transparent; request the full product declaration if formaldehyde sensitivity is a concern.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
