Lower concern. No typical PFAS vector, but no public testing confirms safety.
This rinse-off conditioner has no waterproofing, stain resistance, or nonstick coating needs. The brand hasn't made PFAS claims or sought verification, and no public lab data exists to confirm PFAS absence.

What No 5 Olaplex Bond Maintenance Conditioner is made of, ingredients and materials
No. 5 is a rinse-off aqueous conditioner containing silicones (for slip and shine), Olaplex's proprietary bis-aminopropyl diglycol dimaleate bonding polymer (claimed to repair hair structure), and standard conditioning emollients. The formula is water-based and designed to be removed after application, which limits skin absorption and systemic exposure compared to leave-on products. Silicones themselves are inert in cosmetic-grade formulations and do not bioaccumulate.
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.
Fragrance/fragrance allergens
No. 5 contains fragrance compounds (not fully disclosed by ingredient name); individual sensitization is possible but prevalence is low in rinse-off formats. Patch testing is recommended for those with fragrance allergies or sensitive scalp.
Silicone bioaccumulation on scalp
Repeated use of silicone conditioners can build up on hair and scalp over time, potentially causing dullness or irritation in sensitive individuals. This is a cosmetic concern rather than a toxicological one; rotating products or periodic clarifying treatments mitigate it.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
1,4-dioxane as cosmetic impurity
Dioxane can form as a trace byproduct in ethoxylated ingredients during manufacturing. No public testing or recalls of Olaplex No. 5 for dioxane are on record; risk is theoretical and typical of the product category unless specified otherwise by brand.
Heavy metals
Olaplex does not use azo dyes or antimony-based colorants typical of textiles. Standard cosmetic-grade preservatives and UV absorbers carry minimal heavy-metal contamination risk if sourced from reputable suppliers, and no incidents are documented for this product.
Source, FDA ↗Formaldehyde / VOCs
Modern conditioners typically avoid formaldehyde-releasing preservatives due to regulatory pressure and brand positioning. No evidence suggests Olaplex No. 5 uses imidazolidinyl urea or DMDM hydantoin; this hazard is not established for this product.

The brand's record and disclosure
Olaplex publishes ingredient lists and markets itself as a clean beauty brand, though it does not independently verify PFAS content or publish third-party safety testing. The brand has faced no major safety recalls or regulatory actions related to this product line. Transparency on sourcing and manufacturing is typical for prestige hair care but not exceptional; Olaplex does not disclose supply-chain audits or cosmetic impurity monitoring.
How it compares in its category
Olaplex No. 5 is a mid-to-premium conditioner; its safety profile is consistent with mainstream salon and drugstore silicone-based conditioners. It carries no known hazards that differentiate it negatively from competitors (Kerastase, Bumble and bumble, drugstore brands). The bonding polymer is proprietary but not flagged in regulatory literature as a concern; rinse-off format further reduces risk compared to leave-on treatments or styling products.
If you buy it
Use as a standard rinse-off conditioner, apply after shampooing, leave on for 1-3 minutes, rinse thoroughly. Do not ingest and avoid contact with eyes. Store in a cool, dry place away from direct sunlight to prevent packaging degradation. Replace every 6-12 months after opening or if consistency changes. If scalp irritation or allergic reaction occurs, discontinue and consult a dermatologist; do a patch test first if you have sensitive skin or known fragrance allergies.
