declined in the 1970s as hairstyles became predominantly worn straight and loose. By the 1980s, hairspray’s popularity came back as big hairstyles resurged with the glam metal scene. Prior to 1979, the most popular propellants in hairsprays were CFCs. Owing to environmental concerns, they were replaced. Hair spray can be used for things other than hair. For example in the beauty world one might spray some hairspray on the leg and on the inside of the dress so that the dress won't ride up and stay in place.
