Biolage ColorLast Shampoo Matrix
Lower concern for PFAS; no obvious red flags in typical shampoo formulation.
Biolage ColorLast Shampoo is a rinse-off liquid cosmetic with no disclosed water-resistance, stain-resistance, or coating treatments that would typically require PFAS. Standard shampoo surfactants are not known to contain PFAS, though the brand does not publicly address PFAS content.

The full breakdown
What it's made of and why it matters
Biolage ColorLast is a water-based shampoo formulated with surfactants (likely sodium lauryl sulfate or similar), conditioning polymers, and pigment-protection agents designed to extend color vibrancy. The aqueous base means no volatile solvents or high-temperature stability concerns typical of aerosol or oil products. Its active ingredients target color longevity rather than deep cleansing, which reduces reliance on harsh stripping agents that can destabilize other formulations.
The brand's record and disclosure
Matrix (owner: L'Oreal) maintains ingredient transparency on product labels and safety data sheets but does not publicly champion third-party certifications like EWG Verified or Leaping Bunny. No major recalls or formal safety violations on record for Biolage ColorLast specifically. The brand's PFAS stance is silent, consistent with industry norm for shampoos; no evidence of intentional PFAS inclusion in aqueous formulas.
How it compares in its category
ColorLast sits mid-range in the color-protection shampoo market. Functionally comparable to drugstore sulfate-free alternatives (e.g., Carol's Daughter, SheaMoisture) but marketed at salon price. No structural or chemical advantage over lower-cost competitors; positioning is largely brand and conditioning performance rather than hazard differential.
If you buy it
Use as directed on damp hair; no special precautions required beyond standard shampoo safety (avoid eye contact, rinse thoroughly). For color-treated hair, pair with a sulfate-free conditioner if scalp sensitivity occurs. Replace every 6-12 months depending on frequency of use or if performance visibly degrades. Store in a cool, dry place; do not expose to extreme heat or sunlight, as this may affect preservative efficacy and color-agent stability.
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
Biolage ColorLast contains fragrance (ingredient list includes 'parfum'); specific fragrance compounds not publicly disclosed. Individuals with contact dermatitis or fragrance sensitivity should patch-test or choose fragrance-free alternatives.
1,4-dioxane (non-intentional contaminant)
Aqueous shampoos can harbor trace 1,4-dioxane as a byproduct of ethoxylation in surfactant or emulsifier production. No published testing of ColorLast for this contaminant; risk is industry-wide and typically at parts-per-million levels below regulatory concern.
Preservative sensitivity
Aqueous shampoos require preservatives (likely methylchloroisothiazolinone or parabens, unconfirmed on label). A small percentage of users report scalp irritation or contact dermatitis from preservative systems; risk depends on individual skin reactivity, not product defect.
Heavy metals in colorants
No recalls or public testing data indicating lead, cadmium, or arsenic in Biolage ColorLast pigments. Liquid color-protecting shampoos typically do not concentrate inorganic colorants at levels of concern in cosmetics.
Formaldehyde-releasing preservatives
No evidence that Biolage ColorLast uses formaldehyde releasers (DMDM hydantoin, imidazolidinyl urea, dioxolan) based on industry standard; aqueous shampoos typically avoid these in favor of alternative preservatives.
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.
