Bumble and Bumble Sunday Shampoo
Low-medium concern; shampoo has no functional need for PFAS, with typical brand silence.
This rinse-off liquid shampoo has no waterproofing, grease-resistance, or nonstick function that would drive PFAS use. The brand makes no PFAS claims, which is standard in cosmetics, and the product category carries minimal PFAS risk signals.
We flunk more products than we pass. This one earned its grade. How we grade
Material
aqueous liquid shampoo base (no PFAS-typical coating or treatment function)
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Category baseline
cosmetics is a category where PFAS exposure is more common.
Fragrance allergens (undisclosed composition)
Fragrance is listed as a single ingredient per cosmetic regulations, masking specific component allergens. Individuals with fragrance sensitivity or contact dermatitis history should patch test or review full INCI list on brand website before full use.
Bacterial/microbial growth in liquid formulation
Liquid shampoos rely on preservative efficacy and sealed packaging. Risk is minimal under normal storage but increases if cap left open, water introduced, or product stored in humid bathroom conditions for years.
What’s reassuring
Safe base material
Made from ceramic, mineral, or natural fiber with no PFAS risk.
1,4-dioxane (potential impurity in surfactants)
No published testing or recalls indicate 1,4-dioxane in this product. Rinse-off shampoos carry lower residue risk than leave-on products even if impurity present, due to brief contact time.
Formaldehyde / VOCs
Bumble and bumble does not publicly disclose preservative choice. FDA-compliant limits apply; independent testing by third parties (e.g., EWG, Clean Beauty Council) is not available for this specific product.
Source: ATSDR ↗Heavy metals
Sunday Shampoo is a clear to pale liquid with minimal visible pigmentation, reducing likelihood of intentional colorant use. No contamination reports exist; cosmetic grade materials are regulated but not routine-tested by FDA.

What it's made of and why it matters
Sunday Shampoo is an aqueous liquid formulation typical of premium shampoos: water-based with surfactants, conditioning agents, and fragrance. As a rinse-off product applied briefly to scalp and hair then washed away, dermal absorption is minimal compared to leave-on cosmetics. The liquid format eliminates talc contamination risk and avoids volatile organic compound off-gassing common in powders or aerosols.
The brand's record and disclosure
Bumble and bumble (Estee Lauder-owned) does not publish detailed ingredient transparency reports or third-party certifications like EWG Verified. The brand lists ingredients on packaging in compliance with cosmetic labeling law but does not voluntarily disclose preservative systems, fragrance composition, or heavy metal testing. No recalls or formal safety controversies are on public record for this specific product line.
How it compares in its category
Sunday Shampoo sits in the premium mass-market segment alongside brands like Olaplex and K18. It lacks certification marks (organic, EWG, cruelty-free seals) that some alternatives carry. Formulation approach is conventional rather than reformulated to eliminate traditionally-used preservatives or fragrance allergens, which is typical for this price tier.
If you buy it
Use as directed: wet hair, apply, lather, rinse thoroughly. Store in a cool, dry place to prevent bacterial growth in the liquid formulation. Discontinue if scalp irritation or allergic reaction develops. Replace every 6-12 months depending on usage; liquid shampoos have indefinite shelf life when sealed but can degrade once opened due to exposure.
