Prose Reduces Breakage Non-Stripping Shampoo
Lower-concern product; typical aqueous shampoo has no inherent PFAS trigger, but brand makes no public commitment.
Prose's breakage-reducing shampoo is a liquid cosmetic with no known high-risk PFAS vectors (nonstick, water-repellency, stain resistance). No public PFAS disclosure or testing data exists.

The full breakdown
What it's made of and why it matters
Prose's breakage-reducing shampoo is a water-based liquid formula, the lowest-risk delivery system for personal care products. The 'non-stripping' claim suggests gentler surfactants (likely sulfate-free or mild amphoteric types) and conditioning agents such as silicones, proteins, or oils to coat and protect hair. Water-based liquids do not concentrate synthetic chemicals the way powders or solid formats do, and the rinsing step removes the product entirely after use, limiting skin absorption.
The brand's record and disclosure
Prose does not publish a full ingredient list or safety data sheet publicly; the brand markets customized formulations but offers no third-party certifications (e.g., EWG Verified, Leaping Bunny, or NSF) and has not made explicit commitments to PFAS avoidance or disclosure. No major recalls or safety controversies are on record for this product line. The silence on ingredient sourcing and testing is typical of prestige haircare brands but represents a gap in transparency.
How it compares in its category
Liquid shampoos are inherently safer than solid bars or powders because dilution in water reduces hazard density and ensures removal via rinsing. Prose positions itself as a premium, custom alternative to mass-market brands; comparable products from Olaplex, Briogeo, or Mielle typically disclose more ingredients and some hold third-party certifications. Prose's opacity is a minor disadvantage but does not indicate elevated risk relative to mass-market sulfate-free shampoos.
If you buy it
Use as directed and rinse thoroughly to ensure complete removal from hair and scalp. Store in a cool, dry place away from direct heat or sunlight to prevent formulation separation or degradation. If irritation develops, discontinue and rinse well; shampoos are leave-in-free, so contact time is brief. Replace the bottle if separation, odor change, or visible discoloration appears, indicating possible microbial growth or oxidation.
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.”
1,4-dioxane (synthetic contaminant)
Dioxane is a common byproduct of ethoxylation in mild surfactants used in sulfate-free formulas. Prose does not disclose supplier screening or contaminant testing; the risk is low but not ruled out without third-party verification.
Fragrance allergens and undisclosed components
Prose uses fragrance blends but does not list individual fragrance ingredients, preventing allergy-sensitive consumers from identifying potential triggers. Typical haircare fragrance concentrations are low-risk, but lack of transparency limits informed assessment.
Formaldehyde releasers in preservatives
Preservatives such as DMDM hydantoin or imidazolidinyl urea (both common in shampoos) release small amounts of formaldehyde over time. No public disclosure of Prose's preservative choices; risk is standard for the category but unverified for this brand.
Heavy metals in colorants or trace impurities
No recalls or reports of cadmium, lead, or arsenic in Prose shampoo. Water-based formats do not concentrate metals as easily as pigmented powders or pressed solids; risk is minimal.
Microbial contamination if seal is compromised
Liquid shampoos are aqueous and can support bacterial or mold growth if stored in humidity or if the bottle seal is damaged. Standard risk for any liquid personal care; use normal hygiene and storage practices.
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.
