Prose Alcohol-Free Conditioner
Lower concern; liquid hair care lacks typical PFAS vectors but brand offers no transparency.
As a rinse-off liquid conditioner, this product doesn't need coating, waterproofing, or nonstick treatments where PFAS commonly appear. Prose provides no PFAS disclosure or third-party verification.

What Prose Alcohol-Free Conditioner is made of, ingredients and materials
Prose Alcohol-Free Conditioner is an aqueous (water-based) rinse-off product, meaning it sits on hair briefly before washing away, limiting absorption and systemic exposure. As a liquid conditioner without heat-applied coatings or sustained skin contact, it avoids hazard vectors common to cookware, textiles, or leave-on cosmetics. The formulation is customized per user but typically relies on emollients, silicones, and conditioning agents rather than problematic preservatives or heavy-metal pigments.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Fragrance allergens
Prose does not publicly disclose fragrance components or allergen warnings. Rinse-off contact limits risk, but sensitive scalps may react to undisclosed fragrance mixtures.
1,4-dioxane from surfactant ethoxylation
Liquid conditioners often use ethoxylated emulsifiers (e.g., ceteth compounds) which may contain trace 1,4-dioxane; Prose does not commit to dioxane-free sourcing.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Formaldehyde / VOCs
No evidence Prose uses formaldehyde donors (e.g., DMDM hydantoin) in this product line, but the brand does not confirm preservation systems publicly.
Source, ATSDR ↗Heavy metals
If this product contains colorants, lead or cadmium contamination is theoretically possible; Prose does not publish metal testing data for conditioners.
Source, FDA ↗Microbial contamination if stored improperly
Aqueous products are susceptible to mold or bacterial growth if exposed to moisture; proper closure and storage prevent this, not a Prose-specific failure risk.
How is this PFAS grade calculated?
The brand's record and disclosure
Prose markets personalized hair care and emphasizes clean formulations but does not publish full ingredient transparency or third-party safety certifications on its website. No major safety recalls or regulatory actions against Prose conditioners are on record. The brand is silent on PFAS, fragrance allergen disclosure, and heavy-metal testing in pigments (if colorants are used), which is common but unhelpful for consumers seeking full transparency.
How it compares in its category
Rinse-off conditioners are among the lowest-risk personal care products because contact time is short and ingestion is accidental. Prose's alcohol-free formulation has lower concern for drying hair and scalp irritation compared to alcohol-containing alternatives. The brand sits mid-market for transparency; luxury brands like Aveeno publish allergen statements more openly, while mass-market brands rarely do better than Prose.
If you buy it
Use as directed and rinse thoroughly to minimize residue buildup. If scalp irritation or allergic reaction occurs, discontinue and patch-test on a small area first. Store below 25°C to avoid separation or degradation. No heat risk (unlike leave-on serums); no special maintenance needed. Replace when empty or if product separates visibly.
