Need A Perm? Reconsider
Before the coming of present-day hairstyling machines like blow dryers and anything that they use for perms nowadays, humankind had things like this. Clearly, this is the way one got a perm during the modern insurgency. These machines were designed by a person called Charles Nessler in 1906 and were called extremely durable wave machines (we know, not generally so snappy as perm contraption 1000). These enormous machines were entirely well-known until around the 1940s.
