But the company insists that the tape, a supposed "Hollywood secret," works by "employing the basic principle of fitness to the muscles of the face. Your face needs a trip to the gym, too. An ad for the Star Vibrator from a issue of "Hearst's International. Meanwhile, Victorians believed that vibrations could cure everything from constipation to headaches to "female hysteria.

Max Factor left and his assistants analyze a woman's face in Modern Mechanix has uncovered several other disturbing s and '40s beauty devices, including Isabella Gilbert's metal brace that could dig those smiley dimples right into your face and a vacuum procedure that claimed to suck the wrinkles right out of your skin.

The Glamour Bonnet, which inventor Dr. Ackerman asserted could improve one's complexion by reducing air pressure around the skin, looked more like the equivalent of putting a plastic bag over your head. But, hey, hucksters offered other ideas for getting full breasts.

Why not inflate them like balloons? All you need is more breathing capacity, right—because your lungs are in your boobs? That's what the ads for the Breathing Balloon and Psycho-Expander suggest. If that doesn't work, there was always the Star Vibrator. A ad claims this device will "enlarge the chest to its full beauty. When it comes to hairstyles, the fashion consensus about what kind of hair is most lovely has swung wildly between curly and straight. That's why you have women wrapping their hair in Coke cans one decade, and then flattening their locks with clothing irons the next.

A point winding is almost two dimensional, rather like the spring of a watch spiral. A root winding is three-dimensional much like a spiral staircase or, more properly, a helix.

Thus point winding tends to produce more of a curl, but both produce waved hair when pulled slightly. Point produces a thicker winding and so heat takes longer to penetrate the core of the winding. Root winding is heated over a greater length and the thickness of the winding will depend on the overlap between turns.

Bari-Woollss was probably instrumental in introducing a new factor-redox reduction. In chemistry, this is the opposite of oxidation and can mean the removal of oxygen or, in this case, the addition of hydrogen, which by breaking the bonds of the keratin in the hair, allowed waving to take place more easily. This resulted in addition of a sulfite, bisulfite or metabisulfite to Icall reagents, sulfur dioxide , a reducing agent, being evolved on heating.

The only alternative to sulfites at the time would have been mercaptans which are unpleasant to use. However, later alternatives were found which led to the development of cold-waving.

Bari-Woollss left Icall in about to take over the editorship of an encyclopedic volume on women's hairdressing. By , the process of permanent-waving was well established and its importance can be gauged if one considers that the majority of middle-class women, at a rough estimate, had their hair set once a week and permed perhaps once every three months as new hair replaced the waved hair. Meanwhile, hairdressers sought to improve the process and reduce the work involved; this meant savings at the lower end of the market and yet more women getting their hair permed.

This was also stimulated by pictures of the rich and famous, particularly film stars, who all had their hair permed. This resulted in many copies of the original equipment being made by reputable firms in some cases with innovations of their own:. The manner in which reagents worked when applied to the hair and heated, was not only due to the chemicals they contained, but also the effect of the water. However, this evaporated the water, and it was found that by wrapping the windings with aluminium foil, the hair stayed moist for longer, and also kept the windings upright, facilitating the addition of the heaters.

A further advance was the use of so-called "sachets", a misnomer, because they were small absorbent pads containing certain chemicals, attached to foil or other waterproof material, such as vegetable parchment. These were popular with hairdressers as a labour-saving device, and with manufacturers, as they were only used once and some 20 would be used for a head of hair. There were also changes in the equipment. Icall pioneered the use of plastics in hairdressing equipment, specifically a thermosetting plastic, Bakelite which was used not only because of its electrical properties in the windings of motors and heaters, but in the outer coverings of the heaters.

They were less affected by corrosion and were less likely to burn the fingers of the hairdresser. Icall also used Bakelite for the outer casings of hand-held hair-dryers and also for the large linings of pedestal hair-dryers. It can be imagined that at a time when electrical installations were not to today's standards and at one time were not even grounded, the application of electrical windings to wet hair resulted in enough accidents to worry women.

Icall developed what was called the "wireless" system, in which the electric lead to the heater was replaced by a cord that took the weight of the heater, and the heater was heated by plugging into a socket in the chandelier. Outwardly, the machine looked similar to the earlier model, but at no time was there an electric potential near the head. Also during this time, in the United States a machine-less method that applied preheated clamps over the wrapped rods was invented, In , at the Midwest Beauty Show in Chicago, Ralph L.

Evans and Everett G. McDonough showed a heatless system for the first time. Their method used bi-sulfide solution and was often applied at the salon , left on while the client went home and removed the next day, leading it to be called the overnight wave. With the outbreak of World War II in , all production of such equipment stopped in Europe and hardly recovered afterwards, being replaced either by home heater kits or cold-waving methods.

In , Arnold F. Willatt invented the cold wave, the precursor to the modern perm. The hair was wrapped on rods and a reduction lotion containing ammonium thioglycolate was applied. This chemical breaks open the disulfide linkages between the polypeptide bonds in the keratin; the protein structure in the hair. The disulfide bonds give hair its elasticity, and can be reformed with chemicals.

Next, an oxidation lotion—hydrogen peroxide—was applied to close the disulfide bridges again, and the hair was reformed to the shape of the rod. The entire process took 6—8 hours at room temperature. In the s, acid perms were invented. These ammonia-free acid perms, sometimes called buffered waves, use glyceryl monothioglycolate in the place of ammonia. Acid perms, or buffered wavers, are slower but gentler to the hair.

Heat is usually added by placing the client under a dryer, after covering the wrapped head with a plastic cap. The reaction is endothermic and the additional heat causes the pH to rise from 6. Perms today use this method with sodium thioglycolate instead of ammonium thioglycolate, at a pH of 8 to 9. Perming hair with the sodium thioglycolate method takes only 15—30 minutes of exposure to the sodium thioglyclolate solution before a neutralizer solution is applied to bring the pH back to normal and re-bond the hair.

The permanent relaxer straightens the hair instead of curling it. The same chemical methods can be used for this, but the hair is not wrapped around rods. Other types of modern perms include exothermic perms, which are self timing and self heating; and neutral, or low pH, thioglycolate free perms. Digital perms were introduced in the 21st century and in use especially in modern Asian cultures.

The process was patented and invented by a Japanese company, Paimore Ltd. There are two parts to a perm: the physical action of wrapping the hair, and the chemical phase. Both of these can affect the result. Important physical variables involved are what type of rod is used, how the hair is wrapped and how end papers are used.

Perm (hairstyle) - Wikipedia

The two most common types of rods are straight and concave; each giving a different curl effect. The wrapping method is either spiral or croquinole, and various types and the positioning of end papers can be used with any combination of the above. Generally, smaller rods will produce smaller, tighter curls and increase the appearance of shortening the hair.

The chemical solution used in the perming process is determined by the client's hair type and the pH of the solution. Classic alkaline perms are used for stronger, coarser hair. They work at room temperature and usually contain ammonium thioglycolate in the pH range of Acid perms are used on more delicate or thinner hair.

They require outside heat application and usually contain glycerol monothioglycolate in the pH range of 6. Due to the harsh nature of the chemicals, it is important that contact with the skin be minimized. Modern chemicals are less irritating, but measures should still be taken to reduce contact with anything other than hair.

A poorly performed permanent wave will result in breakage of the disulfide bonds through chemical reduction, because it fails to fix the newly formed bonds. This results in hair that is no longer elastic and flexible, but brittle and fragile.
