Redken Acidic Grow Full System Densifying Conditioner
Lower concern for PFAS; standard rinse-off conditioner with no known PFAS triggers.
Redken's acidic conditioner is a rinse-off cosmetic with typical polymer/silicone conditioning agents. No waterproofing, grease-resistant coating, or nonstick treatment is needed or typical in hair conditioners, so PFAS-containing water-repellent coating chemicals are unlikely.

The full breakdown
What it's made of and why it matters
Redken Acidic Grow conditioner is a water-based emulsion combining silicones (for slip and shine), cationic polymers (for conditioning deposit), and humectants typical of mainstream salon conditioners. The 'acidic' formulation refers to pH tuning to close hair cuticles, not a hazardous acid concentration. No reported use of Teflon-type coating, waxes, or metallic compounds that would trigger acute toxicity concerns in a rinse-off product.
The brand's record and disclosure
Redken is owned by L'Oreal and subject to EU cosmetic ingredient restrictions and voluntary US industry standards, but makes no public commitment to PFAS avoidance or independent third-party testing. The brand has no documented major recalls or chemical controversies specific to this product line. Full ingredient disclosure is available on pack and manufacturer websites, which is standard practice for the category.
How it compares in its category
This product sits in the mainstream premium segment, comparable to other salon-grade conditioners (Pantene Gold Series, SheaMoisture formulas) in composition and hazard profile. Rinse-off conditioners present lower exposure risk than leave-on products because contact time is brief and dilution occurs. No material advantage or disadvantage versus comparable mass-market or prestige alternatives in terms of established safety data.
If you buy it
Apply to damp hair, leave for 1-3 minutes, rinse thoroughly with water. Avoid contact with eyes and mucous membranes; rinse immediately if irritation occurs. Store at room temperature away from direct heat; do not apply to scalp or leave on skin. Discontinue use if rash, itching, or persistent irritation develops and consult a dermatologist.
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 sensitizers
Redken Acidic Grow contains fragrance as listed ingredient; no specific allergen declaration on standard labeling. Individual sensitivity varies; patch testing recommended for those with known fragrance intolerance or sensitive scalp.
1,4-dioxane contamination (residual from synthesis)
Surfactants and emulsifiers used in conditioners can carry trace 1,4-dioxane as manufacturing byproduct. Redken does not publicly disclose testing or removal protocols. Risk is low in rinse-off format, but not independently verified for this specific product.
Formaldehyde releasers
No documented use of formaldehyde-releasing preservatives in current Redken Acidic Grow formulations. Standard industry practice favors safer alternatives; no recalls or alerts on file for this product.
Heavy metals in colorants or opacifiers
Conditioners do not typically employ pigments requiring heavy metal stabilizers. No published data suggests lead, cadmium, or arsenic in this product; regulatory compliance expected for mass-market salon brands.
Microplastic microbeads
Redken Acidic Grow does not list polyethylene or polypropylene microbeads as exfoliants. This is a conditioning emulsion, not a scrub or physical exfoliant product.
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.
