- High hair a hole in the ozone layer: the 80s - NILU
In the mid-80s, we wore big shoulder pads, parachute pants and had enormous hair – thanks to hairspray Most spray containers at that time contained chlorofluorocarbons, AKA CFCs, substances that were used in many products and industries all over the world CFCs release chlorine radicals while exposed to sunlight
- Whatever happened to the hole in the ozone layer?
