Redken Frizz Dismiss Shampoo
Lower concern for PFAS with no known water-repellent or nonstick treatment.
This rinse-off shampoo has no functional need for PFAS since it requires no waterproofing or nonstick treatment. Redken has not voluntarily verified PFAS-free status, and exposure from a rinse-off product would be minimal.

What Redken Frizz Dismiss Shampoo is made of, ingredients and materials
Redken Frizz Dismiss Shampoo is a water-based formulation containing silicones (likely dimethicone or similar) and conditioning agents designed to coat and seal the hair cuticle. Silicones in rinse-off products are not absorbed into skin or systemically, and are rinsed away with water, making exposure minimal. The formula also includes surfactants and preservatives typical of mainstream shampoos; these are regulated ingredients at approved concentrations.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
1,4-dioxane (contaminant in ethoxylated surfactants)
Water-based shampoos may contain trace 1,4-dioxane as a byproduct of ethoxylation in surfactants. Redken does not publicly disclose 1,4-dioxane testing or removal on this product; the concentration, if present, is typically below 10 ppm and is not a documented recall trigger for mainstream shampoos.
Preservative sensitization (methylchloroisothiazolinone and related)
Mainstream shampoos including Redken products commonly use preservatives such as methylisothiazolinone. Rare allergic contact dermatitis has been documented in sensitive individuals; incidence is low but not zero. Patch testing or ingredient checking is advisable if scalp reactions develop.
Silicone accumulation on hair
High silicone content in rinse-off shampoos can deposit on hair over repeated use, especially in fine or thin hair, leading to buildup and weight. This is a cosmetic concern rather than a health hazard, but may necessitate periodic clarification or switching products for long-term users.
Fragrance allergen undisclosure
The product contains fragrance listed as a single ingredient without breakdown of components. Fragrance blends can include known allergens such as limonene, linalool, or cinnamyl alcohol; individuals with fragrance sensitivity should perform a patch test or request full fragrance composition from the manufacturer.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Heavy metals
No documented concerns or recalls involving heavy metals in this shampoo formulation. Cosmetic colorants in shampoos are regulated, and Redken is subject to FDA oversight; no specific testing has flagged contamination in this product line.

The brand's record and disclosure
Redken is owned by L'Oreal and operates under cosmetic industry standards but does not publish detailed ingredient sourcing or third-party safety certifications on this product. The brand has no documented recalls or major safety controversies tied to this shampoo line. Ingredient transparency is limited to the standard label; L'Oreal-owned brands generally comply with FDA and EU cosmetic regulations but do not voluntarily exceed them.
How it compares in its category
Frizz Dismiss Shampoo is a mainstream conditioning shampoo with a silicone-heavy profile, typical of mass-market anti-frizz products. It does not carry eco or clean-beauty certifications and sits in the conventional segment rather than natural or hypoallergenic tiers. For users with silicone sensitivity or preference for silicone-free formulas, alternatives exist; for general use, safety profile is consistent with comparable drugstore brands.
If you buy it
Use as directed, wet hair, apply, lather, rinse thoroughly with water. No special precautions are needed; the product is designed for rinse-off and poses no heat or storage hazards. If scalp irritation or hair buildup occurs after weeks of use, consider switching to a clarifying shampoo occasionally or testing a silicone-free alternative. Store in a cool, dry place and replace when empty or if separation occurs.
