Bumble and Bumble Strong Finish Hairspray
Avoid until clarification provided; hairspray propellants are a PFAS concern vector with no public disclosure.
Bumble and bumble hasn't disclosed PFAS content for this aerosol hairspray. Hairsprays commonly use hydrocarbon or fluorocarbon propellants, with fluorocarbon raising PFAS concerns.

What Bumble and Bumble Strong Finish Hairspray is made of, ingredients and materials
Bumble and Bumble Strong Finish is an aerosolized polymer-based hairspray using propellant gases to atomize film-forming resins that coat hair fibers. The propellant system is the primary unknown, conventional hairsprays rely on hydrofluorocarbon (HFC) or hydrocarbon propellants, some of which contain PFAS compounds or PFAS-derived surfactants to improve aerosol stability. The polymer matrix itself (typically acrylates or copolymers) poses minimal direct hazard once dried on hair, but inhalation of the aerosolized mist during application is the relevant exposure route.
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.
PFAS
Aerosolized propellants (HFC, hydrocarbons) can irritate airways with repeated or unventilated exposure. Individual sensitivity varies; asthmatics and people with compromised lungs face higher risk.
Source, ATSDR ↗Fragrance allergens (if present)
Bumble and bumble products are fragrance-forward and this spray likely contains fragrance compounds that may trigger contact dermatitis, respiratory sensitivity, or migraine in susceptible individuals. Full fragrance ingredient disclosure is not required on product labels in the U.S.
PFAS
Aerosol hairsprays are a known propellant vector for PFAS. Bumble and bumble's lack of disclosure combined with industry-standard HFC/hydrocarbon propellant use suggests possible PFAS-derived surfactants. Exact risk tier depends on propellant supplier and formulation details the brand does not share.
Source, ATSDR ↗What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Polymer film residue on scalp and hair
Acrylate-based polymers in hairspray are designed to remain on hair as cosmetic film. No systemic toxicity established at topical cosmetic use levels; scalp irritation or buildup is possible with daily use without clarifying shampoos.
Formaldehyde / VOCs
No public information identifies formaldehyde in Bumble and bumble Strong Finish. Hairsprays rarely contain this preservative; if present, would be disclosed on ingredient list. Check label for any alcohol-based preservatives that may generate trace formaldehyde under storage heat.

The brand's record and disclosure
Bumble and bumble does not publicly disclose propellant composition, PFAS content, or third-party safety testing on their website or product labels. The brand has no known certifications from organizations that verify PFAS-free formulations (e.g. No recalls or regulatory warnings have been issued for this specific product. The silence on propellant chemistry is consistent with industry-wide lack of transparency; most major hairspray brands do not voluntarily reveal PFAS-adjacent chemistry.
How it compares in its category
Strong Finish is a premium-priced aerosol hairspray in a category where solid-stick and pump-spray alternatives exist with lower PFAS exposure potential. Most aerosol hairsprays from major brands (L'Oreal, Schwarzkopf, TRESemmé) share the same propellant transparency gap. Bumble and bumble's positioning as a luxury salon brand does not correlate with better chemical disclosure than mass-market competitors. Dry texture sprays and wax-based pomades avoid the aerosol inhalation route entirely.
If you buy it
Apply in well-ventilated spaces (open window or bathroom fan running) to minimize inhalation of aerosolized polymers and propellants. Keep spray distance 8-12 inches from scalp and hair to reduce direct mist exposure. Do not use in enclosed bathrooms without ventilation. If using regularly (daily or multiple times per week), rotate with non-aerosol styling products or consider switching to pump-spray or stick formulas to lower cumulative propellant exposure, especially if pregnant or immunocompromised.
