Schwarzkopf Osis+ Session Extreme Hold Hairspray
Avoid until the brand discloses or independent testing confirms safety; hairsprays historically rely on fluorinated polymers.
Schwarzkopf offers no public statement on PFAS in this aerosol product. Hairsprays commonly incorporate fluorinated acrylate or Teflon-family coating resins for hold and water resistance.

What Schwarzkopf Osis+ Session Hold Hairspray is made of, ingredients and materials
Osis+ Session is a polymer-resin aerosol suspension (typical for hold hairsprays) propelled by butane/isobutane mix. The resin binder creates the hold effect but is typically a Teflon-family coating or acrylic-based film former; Schwarzkopf does not publicly specify which, raising PFAS uncertainty. Aerosol propellants themselves are not toxic at use distances, but the polymer matrix and any volatile co-solvents (alcohols, water) are the primary inhalation concern during application.
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.
Volatile organic compounds (VOC) and propellant inhalation
Butane/isobutane propellants and solvent alcohols in hairsprays are known respiratory irritants with acute inhalation risk during application. No specific testing published for this product, but category-wide concern in aerosol formulations.
PFAS
Schwarzkopf does not specify whether the hold-resin is fluorinated (PFAS-containing) or acrylic-based. Teflon-family coating are common in aerosol hairsprays for hold durability; absence of claim to non-fluorinated status suggests potential PFAS presence.
Source, ATSDR ↗Fragrance allergens and undisclosed ingredients
Hairsprays often contain fragrance blends that can trigger contact sensitivity or scalp/respiratory irritation in sensitive individuals. Schwarzkopf does not break down fragrance components on the label, typical of the category.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Formaldehyde / VOCs
No independent testing or brand disclosure found linking Osis+ Session to formaldehyde releasers. Aerosol formulations typically use alternative preservatives (phenoxyethanol, parabens) rather than formaldehyde donors.
Source, ATSDR ↗Heavy metals
This is a clear/colorless or light-tinted aerosol; pigment-based heavy metals (lead, cadmium in dyes) are not a typical concern for colorless hairsprays. No recalls or testing flagged this hazard.

The brand's record and disclosure
Schwarzkopf (Henkel subsidiary) maintains minimal public disclosure on PFAS content in hair-care products and has not signed transparency pledges common among competitors (e.g., ZDHC Gateway, Cradle to Cradle). The brand has no recent recalls or safety controversies tied to this specific product, but absence of disclosure is itself a red flag in a category where fluorinated polymers remain industry standard. Parent company Henkel has faced PFAS scrutiny in industrial contexts but has not proactively addressed cosmetic/personal-care PFAS.
How it compares in its category
Aerosol hairsprays occupy a higher-risk position than pump-spray or gel alternatives because inhalation exposure is harder to control. Osis+ Session is mid-market priced; competitors like Tresemme or drugstore aerosols face identical PFAS uncertainty, while premium brands (e.g., Bumble and bumble, some salon brands) occasionally disclose non-fluorinated polymers. No hairspray aerosol in this segment has definitively claimed PFAS-free status with third-party backing.
If you buy it
Use in well-ventilated spaces (bathroom exhaust on, window open) to minimize polymer and propellant inhalation. Apply at arm's length (8-12 inches from scalp) in short bursts rather than continuous spraying; do not inhale during or immediately after application. Replace every 6-12 months or when spray pattern weakens (sign of propellant loss or clog). Consider switching to pump-spray or gel hold products if concerned about aerosol inhalation exposure; contact Schwarzkopf directly to request PFAS disclosure or testing results.
