Thickening Spray vs OSiS+ Elastic Light Hold Hairspray: which is safer?

Where these two actually differ

• We flag Volatile Organic Compounds (VOCs) from solvents, Fragrance allergens and sensitizers and Propellant-related respiratory irritation on the Bumble and bumble and not on the Schwarzkopf.
• We flag Inhalation of propellant and spray particulates, Volatile organic compounds (VOCs) and formaldehyde releasers in polymeric resins, Fragrance allergens and undisclosed fragrance components and PFAS in propellants or water-resistant additives (per PFAS grade) on the Schwarzkopf and not on the Bumble and bumble.
• The Bumble and bumble is spray formulation (polymers, propellant, solvents) where the Schwarzkopf is aerosol spray (propellant + polymeric resins, typical hairspray formulation), which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
• We are less certain about the Schwarzkopf grade, at 45% confidence against 72%, because it discloses less.
