What OSiS+ Session Label Strong Hairspray is made of, ingredients and materials
OSiS+ Session Label Smooth Strong is an aerosol hairspray combining alcohol (solvent and fast-drying agent), film-forming resins (typically acrylate or vinyl-based polymers for hold), and a propellant (likely hydrocarbon gas or compressed air). The resin coating on hair is designed to be temporary and washable. Alcohol content evaporates quickly, minimizing skin exposure 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.
Inhalation of propellant and volatile compounds
Aerosol hairsprays release hydrocarbon or compressed-gas propellants and alcohol vapors during use. Chronic inhalation in poorly ventilated spaces may cause respiratory irritation; acute over-exposure is unlikely in normal application.
Fragrance allergens
Like most styled hairsprays, this product likely contains fragrance compounds. Individuals with sensitivity to cosmetic fragrances may experience scalp or respiratory irritation; full fragrance ingredient list is not publicly disclosed.
Resin buildup and scalp irritation
Repeated application without adequate washing can lead to polymer residue accumulation on hair and scalp, potentially causing dryness or mild irritation. This is a usage issue, not a formulation toxicity concern.
Eye contact risk
Aerosol spray misdirection or user error can deliver product to the eye; alcohol and resin solvents cause stinging and temporary discomfort. Standard caution label applies.
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 established data indicates Schwarzkopf OSiS+ Session Label contains formaldehyde releasers. Hairsprays typically use alternative preservatives, but product-specific ingredient disclosure from Schwarzkopf would confirm.

How it compares in its category
Aerosol hairsprays are a mature product category with consistent formulation approaches across brands. OSiS+ Session Label sits in the mid-to-premium segment; it is chemically similar to drugstore and professional alternatives in propellant type, resin chemistry, and alcohol load. No distinctive safety profile separates it from competitors.
If you buy it
Apply in a well-ventilated area to minimize inhalation of alcohol vapors and propellant. Avoid spraying near eyes or open flames. Do not puncture or incinerate the aerosol can. Store upright at room temperature away from heat. Wash hair regularly to remove resin buildup; no special skin precautions needed for normal use.
