CFCs In Aerosol Sprays

In the 1970s, hairspray, deodorant, and shaving cream cans were all powered by chlorofluorocarbons (CFCs). These chemicals were destroying the ozone layer. Scientists discovered the hole in the ozone layer in 1985, and the Montreal Protocol banned CFCs in 1987. Today, aerosol sprays use safer propellants, and the ozone layer is slowly healing. But back then, we were literally spraying holes in the sky.
