Function of Beauty Wavy Hair Shampoo
Lower concern for PFAS; liquid shampoos rarely require fluorinated additives, but no public disclosure.
Function of Beauty's wavy shampoo is a rinse-off liquid cosmetic with no known PFAS-prone application (no water-repellency, stain resistance, or anti-stick coatings needed). The brand does not publicly disclose PFAS testing or avoidance. No third-party verification or independent lab data is publicly available to confirm absence.

The full breakdown
What it's made of and why it matters
Function of Beauty Wavy Hair Shampoo is a water-based liquid formulation containing standard anionic and amphoteric surfactants (cleansing agents), silicones or polymers (conditioning), humectants, and preservatives. The brand offers customization but does not publish full ingredient disclosure for proprietary blends. Liquid shampoos pose minimal leaching risk compared to bar or solid formats, and water is the dominant solvent, which limits volatile organic compound (VOC) off-gassing.
The brand's record and disclosure
Function of Beauty markets itself as a personalized beauty brand but maintains limited transparent ingredient disclosure; full formulations are not published online. No significant safety recalls, regulatory actions, or third-party certifications (e.g., Cradle to Cradle, EWG Verified) are on record for this product. The brand has not publicly committed to PFAS-free or heavy-metal testing standards, and does not appear on environmental or safety watchlists as of available public records.
How it compares in its category
Function of Beauty sits in the premium direct-to-consumer shampoo market, positioned between mass-market drugstore brands and certified natural lines. Compared to brands with third-party certifications (Sulfate-Free, Paraben-Free claims are common but not independently verified here), this product lacks external validation. The customization model does not itself reduce chemical hazard; ingredient safety depends on the actual formula chosen, which varies by order.
If you buy it
Store in a cool, dry place away from direct heat or sunlight to slow preservative degradation. Use as directed; avoid contact with eyes. If scalp irritation or allergic reaction occurs, discontinue and rinse thoroughly. Because full ingredient lists are not publicly available, individuals with known fragrance or preservative sensitivities should contact the brand directly before purchase to confirm absence of common triggers (e.g., methylchloroisothiazolinone, sodium laureth sulfate).
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.”
Preservative system (1,4-dioxane, formaldehyde releasers)
Water-based shampoos require antimicrobial preservatives; common options include sodium benzoate, phenoxyethanol, or imidazolidinyl urea (a formaldehyde releaser). Function of Beauty does not disclose which preservatives are used. 1,4-dioxane is a known contaminant in shampoos using ethoxylated surfactants but is not an intentional ingredient.
Fragrance allergens and undisclosed fragrance chemicals
Shampoo formulations typically contain fragrance blends, which are protected as trade secrets under INCI labeling rules. Function of Beauty lists 'fragrance' as a single ingredient without disclosure of component chemicals. Individuals sensitive to common fragrance allergens (limonene, linalool, eugenol) cannot verify absence prior to purchase.
Heavy metals in colorants or pigments
No recalls or public reports of lead, cadmium, or antimony contamination in Function of Beauty shampoos. Shampoo formulations contain minimal pigments compared to cosmetics; risk is low but unverified without third-party testing disclosure.
Microplastic microbeads
Function of Beauty shampoo is a liquid formula; microplastic microbeads are primarily found in scrub or exfoliating formats. No evidence of microplastic content in this product line based on available information.
Coating/container leachables (if packaged in plastic)
If the product bottle is polycarbonate or polyvinyl chloride (PVC), long-term storage may result in leaching of BPA or phthalates into the product, particularly if stored warm. Function of Beauty does not specify bottle material composition publicly. Ensure storage in a cool environment regardless of plastic type.
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.
