#18: Perms
Originating in the 1950s, perms became iconic in the 70s and 80s. At hair salons, women got their hair curled for around $25 ($230 today), reflecting a distinctive style popularized during that era.
The extensive procedure combined chemicals, heat, and curlers to craft the famed look, embraced by pin-up girls and Hollywood’s finest. However, the trend’s downfall was due to the significant hair damage caused by these harsh chemicals.
