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.
