The article highlights a once-popular invention from the 1950s that many people no longer recognize: the permanent wave machine, used for giving perms. Invented by Marjorie Joyner, who patented the device, it featured a round top with cords and attachments to curl hair. Common in beauty salons at the time, it promised faster perms, but it had flaws such as tangled hair and the risk of burns if left on too long. While revolutionary during its era, these imperfections led to its decline, and today, few remember this significant beauty innovation.
