hairspray

Hairspray is a cosmetic product designed to hold hair in place after styling. It is typically applied as an aerosol or pump spray and forms a thin film over the hair to maintain shape and reduce frizz.

Most formulations rely on a film-forming polymer dissolved in a volatile solvent. Common polymers include polyvinylpyrrolidone (PVP) and various acrylate copolymers. The active film dries quickly as the solvent evaporates, leaving a flexible or, in stronger formulas, a rigid film. Propellants such as butane, propane, or isobutane are used in aerosol sprays; non-aerosol variants use pump mechanisms. Many products also contain alcohol (ethanol or isopropyl) or water, conditioning agents, fragrances, and occasional plasticizers to adjust flexibility and texture.

Hold levels range from light to extra strong, with some products marketed as humidity resistant. The user can layer products in thin coats for firmer hold, allowing each pass to dry before applying more.

Usage and care: Hold the can upright, 20–30 cm from the head, and apply in short bursts from a distance to avoid saturation. Allow each layer to dry before styling further. Residue can be brushed out, but heavy buildup may require washing.

Safety and environmental notes: Hairsprays are flammable due to hydrocarbon propellants and solvents, so they should be kept away from heat or flames. Prolonged inhalation or eye contact can cause irritation; some individuals may be sensitive to fragrances or alcohol. Overuse can lead to hair stiffness or dryness, tangling, and buildup on hair and scalp. Sustainable formulations seek to reduce VOCs.

History: Hairspray became widely used in the mid-20th century, offering a quick means to fix hairstyles and enable more elaborate looks.
