How A Hair Curler Works
"Curlers in your hair, shame on you!" This was the sentiment expressed in a Clairol commercial to sell their new electric rollers invented in the late 1960s. Funny thing was ... it worked! Though women have been curling their hair by wrapping it around some sort of round tool or roller for centuries, electric hair curlers have become the standard in the beauty industry. Where women used to go out of their houses in droves every morning with their hair wrapped in curlers and covered loosely by a cap or scarf, today most women use rollers heated by electronic components, enabling them to style their hair completely before leaving the house. The convenience and ease of use offered by electric hair curlers, or 'hot rollers,' is something millions of women swear by, and they wouldn't go back to the 'shameful' circumstance of having to go out with those old-fashioned metal or plastic rollers all over their heads. So, why do hot rollers seem to work so much better than their dated counterparts? The answer, simply put, is heat.
History of curlers
Hair curling is the process of wrapping the hair around a round tool, and it's done not just to curl the hair, but also to soften the hair follicle and control frizz. Women changing the look and feel of their hair into curly or wavy styles dates back as far as Egyptian times. Back then, just as today, many women would wear wigs to change the appearance of their hair. Curling the hair became a mainstay in the beauty industry by the 18th century with powdered wigs, and by the 20th century, curling the hair became as common a thing as washing it. In ancient Roman times, women often wore their hair up in tightly wounded curls. Heat has been a component in hairstyling since these ancient times, when many women would use the heat from an oven to make their hair more curly. Even the modern curling iron, which is a heated wand used to wrap the hair around it and thereby curl it, dates back as far as ancient Babylonia and Greece. In these times, women would use a tool fashioned out of metal tongs that were actually heated over an open flame. Needless to say, it was difficult to control the temperature of such a utensil, making this form of hair curling pretty dangerous. The first electric curling iron was invented in 1959 by a company in France that is now owned by the well-known company Conair. Modern curling irons have evolved and are much safer and effective than even those of just a half century ago.
How hair curlers work
Electric curlers, like manual hair curlers, are round rollers that are typically made of plastic. They have an electrical resistor positioned inside them in order to generate heat. As in many electric utensils, a circuit board made of material that does not conduct electricity, is used to hold the electronic components such as capacitors and resistors that hold and manage the electrical charge. Heat transfer elements inside the curlers for conducting heat from the resistors to the cylindrical walls include a heat-sink, a device which transfers heat. This surrounds the resistor and conforms to the inner surface of the hair roller. These electronic components carry the heat of the resistors to the outer wall of the curler. When the curler heats up, the user wraps the hair around each roller and leaves it in for a specified number of seconds or minutes (depending upon the style desired). Curling irons work in much the same way, as they are heated by electronic components that curl the hair that is wrapped around it, usually a section at a time. How tightly the hair sections curl typically is dependent upon the size of the curling iron, with larger curling irons creating softer curls, and smaller models creating tighter curls.
If you're a woman who likes to change up your straighter hair with a curly or wavy style, chances are you're familiar with hair curlers. Though women have been opting for curlier styles for centuries and trying varied means of achieving these, hair curlers that are powered by electricity for heat have been the norm in the beauty industry for decades. Millions of women use hair curlers with electronic components for curling their hair daily, as the convenience of using these has made hair styling that much easier.
