(Redirected from Permanent wave)
A permanent wave, commonly called a perm, is the chemical and/or thermal treatment of hair to produce waves or curls. The use of the word 'permanent' is justified insofar as when the wave is permed, it remains so; however, as the hair grows, the new hair that grows has not been waved, while cutting the hair from the end removes that which is waved, giving the impression that the permanent wave gradually disappears. In cosmetology, it is termed a type of curl reformation.

First Prize won at the Hairdressing Fashion Show London, 1935, using an Icall permanent-waving machine. The hair is shorter even than in the 20's and curls/waves are restricted to the back and sides, revealing the ears and neck. The colours were achieved by adding pigments to the setting lotion.

History
Historically, caucasian women have wished to have wavy or curly hair which seemed more attractive than the more common straight hair. Attempts to curl it by wetting and winding or tying with paper produces only superficial effects. So called water- or finger- waving or setting can be produced by manipulating the wet hair with the fingers, using a viscous lotion (generally made with tragacanth gum) to hold it in place. Washing would immediately destroy the waving. High temperatures were known to be effective for waving hair but impractical unless applied to hair separated from the scalp, which is how wigs were made.
The first person to produce a practical thermal method was Marcel Grateau in 1872. He devised a pair of specially manufactured tongs, in which one of the arms had a circular cross-section and the other a concave one, so that one fitted inside the other when the tongs were closed. The tongs were generally heated over a gas or alcohol flame and the correct temperature was achieved by testing the tongs on a newspaper - if the paper browned slightly it was about right. The waving itself was safe if care was taken to keep the tongs away from the scalp. The procedure was to comb a lock of hair towards the operator moving the comb slowly with one hand to maintain some tension, while with the other hand applying the tongs to the hair successively down the lock of hair towards the point. Each time the tongs were applied, they were move slightly in a direction normal to the lock of hair, thus producing a continuous flat or two-dimensional wave. Skill using the wrist could produce sligh t variations of the wave. Thus, Marcel waving produced a two-dimensional wave, by thermal means only and the change was produced by plastic flow of the hair rather than by any chemical means. Because of the high temperature used, the process tended to degrade the hair. However, in spite of its drawbacks, forms of Marcel waving have persisted until today, when speedy results and low cost are important.
Until the start of the twentieth century, women's hair was not cut, but as the demand for self-determination grew amongst women, it was shortened so that it did not pass the lower end of the neck. This was not only a political gesture but a practical one as women began to take over men's work due to the great shortage of labour during the First World War (see Suffragette). At the same time, electricity which at first had been introduced mainly for lighting and industrial use, began to be used for heating and the application of the electric motor at the small business and domestic level. As shorter hair was improved in appearance by waving even more than long hair, it was only a matter of time before an improved form of waving appeared.

Nessler
An early alternative method for curling hair that was suitable for use on people was invented in 1906 by German hairdresser Charles Nessler (18721951). 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 next to human skin. His method, called the spiral heat method, was only useful for long hair. The hair was wrapped in a spiral around rods connected to a machine with an electric heating device. Sodium hydroxide, a strong alkali, was applied and the hair was heated (212; 100 or more) for an extended period of time. The process used about twelve, two-pound brass rollers and took...(and so on) To get More information , you can visit some products about thinning scissor, synthetic wig, pimple cream, wholesale ice cream, olive oil body lotion, ps2 memory card reader, reach toothbrush, citric acid powder, hair dryer straightener, emu oil acne, .
