Hair spray bottle A hairspray bottle, also known as a hair spray hairspray container, is a common grooming and styling product used to apply hair spray to the hair. Hair spray is a cosmetic product that helps hold hairstyles in place, add shine, and control frizz. The hairspray is typically contained in a pressurized canister, and it is dispensed through a nozzle in a fine mist when you press down on the nozzle. The aerosolized spray allows for even distribution and precise application, making it a popular choice for hairstyling.
