Hair spray

[1] Hair sprays consist of the following components: concentrate, plasticizers, luster agents, and fragrances, as well as propellants.

[2] The copolymer mixture is usually adjusted to achieve the desired physical properties (adhesive strength, foaming, etc.

), using plasticizers such as aminomethyl propanol, surfactants such as benzalkonium chloride, and other agents like dimethicone.

In 1968 at the feminist Miss America protest, protestors symbolically threw a number of feminine products into a "Freedom Trash Can."

These included hairspray,[7] which was among items the protestors called "instruments of female torture"[8] and accoutrements of what they perceived to be enforced femininity.

By the 1980s, hairspray’s popularity came back as big hairstyles resurged with the glam metal scene.
