Model-based grades, not lab tests. We flunk more than we pass. How grading works
PFAS in Shampoo, Which Brands Grade Best and Worst
Based on available materials and data reviewed for this guide Puracy Public Goods Shampoo Refill and Credo Beauty Roz Salt Scalp Scrub currently sit at the top of our shampoo database, each with a model-based estimate of 100/100 and an overall grade of Excellent. Both formulations show no evidence of PFAS found in reviewed sources, a distinction from a lab-verified claim, and both are worth a look if you're trying to reduce exposure to fluorinated compounds in daily hair care.
This guide compares fifteen graded shampoo and scalp-care products, ranking from Excellent-tier formulas with high scores to Excellent-tier formulas with more moderate scores, so you can see how brand claims, ingredient disclosure, and our model's estimates line up. No product on this list is labeled "PFAS-free" as a matter of fact; instead we describe grades as lower concern or higher concern based on available materials, not as certainty from a laboratory.

The Top Tier, 100/100 Estimates
Puracy Public Goods Shampoo Refill
Materials, Positioned as a plant-derived, refill-format cleanser. Brand claims, Puracy markets this line around simple, non-toxic ingredient sourcing; these are brand-stated claims, not independent lab verification. Pros, Highest score in our shampoo database, refill packaging may appeal to sustainability-minded buyers, no evidence of PFAS found in reviewed sources. Cons, A high model score reflects available disclosure and materials data, not a guarantee that every batch or every ingredient supplier is chemically identical over time.
Credo Beauty Roz Salt Scalp Scrub
Materials, A salt-based scalp scrub rather than a traditional liquid shampoo, sold through Credo's curated clean-beauty retail model. Brand claims, Credo requires vendors to meet an internal restricted-ingredient list, a brand and retailer-level claim rather than a third-party lab certification for this specific SKU. Pros, Ties with the top score in our database, retailer-level ingredient screening adds a layer of scrutiny beyond the manufacturer alone. Cons, Scalp scrubs serve a different function than daily shampoo, so this may be a supplement to, not a replacement for, your regular wash routine.
Strong Runners-Up, 90/100 Estimates
Puracy Puracy Natural Shampoo
Materials, A fragrance-free, dye-free formula frequently recommended for sensitive scalps. Brand claims, Vanicream markets the product as free of common irritants like dyes, masking fragrances, and certain preservatives; again, brand-stated rather than independently lab-confirmed for PFAS specifically. Pros, Strong score, minimalist ingredient philosophy generally correlates with fewer undisclosed additives. Cons, Minimalist formulas can sometimes underperform on styling or fragrance experience compared to more heavily formulated competitors.
A large group of familiar drugstore and salon-brand shampoos, including multiple Head & Shoulders variants, several Olaplex No.4 listings, and the Aussie Miracle Moist and Total Miracle lines, land at 75/100. This is still graded Excellent in our system, but it sits meaningfully below the 90 to 100 tier.
Materials, These are conventional mass-market formulations with more complex ingredient lists (silicones, synthetic conditioning agents, fragrance blends) than the minimalist entries above. Brand claims, Procter & Gamble (Head & Shoulders) and Olaplex both publish general ingredient transparency pages, but none of the listed products carry a specific third-party PFAS-free certification in the materials we reviewed. Pros, Widely available, dermatologically tested for dandruff or bond-repair claims, no evidence of PFAS found in reviewed sources at the time of grading. Cons, Lower score than the top tier suggests less available disclosure or more complex synthetic content, which our model weights conservatively. Score differences between near-identical product names (for example, the two separate Olaplex No.4 listings) likely reflect differences in disclosed formulation data available at the time each was reviewed, not necessarily a real-world safety gap.
