Perm (hairstyle) facts for kids
A permanent wave, commonly called a perm, is the chemical treatment of hair to produce curls.
Perms may be applied using thermal or chemical means. In the latter method, chemicals are applied to the hair, which is then wrapped around forms to produce waves and curls. The same process is used for chemical straightening or relaxing, with the hair being flattened instead of curled during the chemical reaction.
History
The first chemical treatment for curling hair that was suitable for use on people was invented in the year 1906 by the German hairdresser Karl Nessler (1872-1951). He used a mixture of cow urine and water. The first public demonstration took place on October 8, 1906, but Nessler had been working on the idea since 1896. Previously, wigs had been set with caustic chemicals to form curls, but these recipes were too harsh to use on human skin.

A Wireless Permanent-Waving Machine designed by Icall in 1934, in which the heaters were disconnected before applying to the head, known as the "falling-heat" method. The heaters were bulkier so as to store more heat, since they began to cool as soon as applied. The heat was controlled according to the type of hair by a thermostat control.
