Redken Color Extend Magnetics Shampoo
Lower concern; rinse-off cosmetic with no known PFAS triggers, though brand discloses nothing.
Redken Color Extend Magnetics Shampoo is a rinse-off hair product with no typical PFAS risk markers, it lacks water/stain repellency claims, non-stick coatings, or aqueous-film-forming treatment language. The brand makes no PFAS disclosures either way.

The full breakdown
What it's made of and why it matters
Redken Color Extend Magnetics is a surfactant-based aqueous shampoo formulated with silicones and polymers designed to coat and protect color-treated hair. The silicone-polymer system (often dimethicone or amodimethicone variants) is rinse-off and does not accumulate systemically. No known hazardous preservative systems, heavy metals, or restricted dyes are listed in available product disclosures, and the rinse-off nature of shampoos means exposure duration is seconds to minutes.
The brand's record and disclosure
Redken (L'Oreal USA subsidiary) does not publicly disclose PFAS content or commit to PFAS phase-out, though the brand maintains general cosmetic safety compliance. No recalls or established safety controversies specific to this line are on record. Redken provides standard ingredient lists but does not pursue third-party certifications such as EWG Verified or Clean Beauty standards, relying instead on regulatory compliance.
How it compares in its category
This product sits in the mainstream color-care shampoo segment. It is chemically similar to comparable brands (Pantene Gold, Garnier Color Shield) in relying on silicone-polymer conditioning matrices. Unlike sulfate-free or natural-positioned alternatives, it uses standard anionic surfactants, which are safe at rinse-off concentrations but may be drying to some hair types. It does not stand out as a hazard outlier or as exceptionally transparent in safety communications.
If you buy it
Use as directed: small amount (dime-sized) lathered and rinsed thoroughly. No ingestion risk in normal use; accidental eye contact requires water rinse. Store in a cool, dry place to prevent contamination and preserve efficacy. Replace when empty; do not leave opened product in high-humidity bathrooms long-term, as standing water in bottles can promote microbial growth. Discontinue if scalp irritation occurs; patch test if you have known fragrance sensitivities.
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.”
Fragrance allergens and undisclosed fragrance components
Shampoos list 'fragrance' as a catchall ingredient; Redken does not itemize fragrance constituents. Individuals with fragrance sensitivities or contact dermatitis may react. No specific allergen recalls are on record for this line.
Preservative-related irritation or contact sensitization
Standard cosmetic preservatives (typically methylisothiazolinone or parabens in rinse-off products) are used at safe levels and quickly rinsed away. No documented issues with this product specifically, though sensitive scalps may react to any surfactant system.
Silicone and polymer buildup on hair
Repeated use of silicone-heavy formulas can accumulate on hair shafts, requiring periodic clarifying shampoos to remove. This is a cosmetic concern (dullness, weight) rather than a health hazard, but relevant to product performance over time.
Heavy metals in colorants or pigments
No recalls or disclosed heavy metal contamination in Redken Color Extend products. Mainstream U.S. cosmetics are subject to FDA limits on lead and other metals, though testing is not routine for all batches.
1,4-dioxane contamination from surfactant manufacturing
Surfactant-based rinse-off cosmetics may contain trace 1,4-dioxane (VOCCR Group 2B hazard) from ethoxylation processes. Redken does not disclose testing or removal efforts. Exposure is minimal in a seconds-long rinse, but sensitive individuals may prefer brands that certify its absence.
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.
