Well let’s start with a little History:

The creator of the product we have coined a “Perm” was Garrett Augustus Morgan,Sr. He was born in Paris, Kentucky on March 4, 1877. Garrett was a natural born inventor. Among his creations was the three-position traffic signal, a traffic management device that greatly improved safety along America’s streets and roadways. Morgan’s technology was the basis for the modern-day traffic signal and was a significant contribution to development of what we now know as Intelligent Transportation Systems.

Why do you care about all of this? Because he invented the hair relaxer! While working in his workshop attempting to invent a new lubricating liquid for the machine needle, it is widely believed that Morgan wiped his hands on a wool cloth, returned the next day, found the woolly texture of the cloth had “smoothed out”, and set out to find how the liquid chemical had changed the texture as it had. He experimented on an Airedale dog, known for their curly textured hair, and the effect was successfully duplicated.

Morgan then tried his lubricating liquid invention on himself, called it a “hair refining cream”, and thus patented the first chemical hair straightener. He founded a personal grooming products company which included hair dying ointments, curved-tooth pressing combs, shampoo, hair pressing gloss, and the one that started it all: the “G.A. Morgan’s Hair Refiner Cream” (advertised to “Positively Straighten Hair in 15 Minutes”).
