Verb Dandruff Shampoo
Lower concern; typical liquid shampoo with no known PFAS pathway, but brand offers no transparency.
Verb Dandruff Shampoo is an aqueous cosmetic with no inherent need for PFAS (not a water-resistant, stain-resistant, or nonstick product). Liquid shampoos rarely contain PFAS, though some cosmetics use fluorinated UV filters or film-forming polymers.

The full breakdown
What it's made of and why it matters
Verb Dandruff Shampoo is an aqueous surfactant-based formulation designed to address scalp flaking via anti-dandruff actives (likely zinc pyrithione or salicylic acid, common in this category). The product contains standard cosmetic preservatives and emulsifiers typical of mass-market liquid shampoos. Aqueous solutions present minimal risk for leaching or degradation compared to solid formulations or those with volatile components.
The brand's record and disclosure
Verb is a consumer haircare brand without major publicly documented recalls or safety controversies on record. The brand does not actively promote third-party certifications (e.g., EWG verification, cruelty-free badges) or publish detailed ingredient sourcing and safety data sheets. Product labeling includes a standard ingredient list but lacks extended transparency statements on preservative systems or heavy metal testing, which is typical, though not exceptional, for the category.
How it compares in its category
Dandruff shampoos vary widely in active-ingredient choice and preservative robustness. Verb's formulation sits in the mainstream commercial tier, neither premium (with third-party testing) nor budget basement (with higher contamination risk historically). Competitors like Head and Shoulders and Nizoral have more extensive safety documentation; indie brands sometimes offer cleaner preservative profiles but less regulatory oversight.
If you buy it
Use as directed on the label, typically 2-3 times weekly; avoid leaving concentrate on scalp for extended periods to minimize irritation risk. Store in a cool, dry place away from direct sunlight to preserve preservative efficacy. Discontinue use if rash, burning, or unusual flaking develops and consult a dermatologist. Replace bottle if seal is compromised or product shows visible discoloration or separation.
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 (preservative contaminant)
Liquid shampoos sometimes contain trace 1,4-dioxane as a byproduct of ethoxylated surfactants, though modern manufacturing controls limit this. No specific test results for Verb Dandruff Shampoo are publicly available; typical commercial shampoos show minimal to undetectable levels if well-manufactured.
Formaldehyde releasers
Some preservative systems (e.g., imidazolidinyl urea, dmdm hydantoin) release small amounts of formaldehyde. Verb's ingredient list would need to be cross-checked; many mainstream brands have phased these out in favor of gentler systems, but absence of public disclosure prevents certainty here.
Heavy metals in pigments or colorants
Shampoos typically contain minimal added pigments; dandruff shampoos are usually opaque white or light yellow from actives and suspended minerals, not synthetic colorants. No specific contamination reports exist for Verb products in this category.
Fragrance allergens
Shampoos include fragrance compounds to mask the odor of actives and preservatives. Verb does not disclose fragrance ingredient breakdown on typical retail labeling. Individuals with fragrance sensitivity or scalp inflammation should perform patch testing before full use.
Scalp irritation from active ingredients
Dandruff shampoo actives (zinc pyrithione, salicylic acid) are well-established but can cause drying, burning, or contact dermatitis in sensitive individuals. This is a known category risk, not specific to Verb, but worth monitoring during initial use.
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.
