Hair rollers (hair curlers) are tools used for hair curling. They are made of solid materials (plastic, ceramic) or polymeric foam. Rollers can be used on dry or wet hair, and in some cases, for a more permanent effect, they can be heated before or after the hair is wrapped around them.
Curlers were used in hair styling since antiquity. Ancient Egyptians wrapped locks of hair around wooden sticks and heated them with the sun for a long-lasting effect. Noble people in Ancient Rome also used rollers to turn their long hair or wigs into tight curls. Ancient Greeks made hollow metal rods and heated them in wooden ashes before using them as curlers.
The hair rollers became especially popular in the 18th century when perfectly shaped and powdered wigs conquered public fashion. However, improvised and undeveloped tools were still used for curling.
The first patented system for long-lasting curls appeared only in 1906, in Germany. The hair stylist Karl Neslar introduced curlers connected with heating machine, operating on the principle of electrical resistance. The curlers stayed away from the scalp by weights, preventing it from burning. Before use, hair was smeared with caustic soda. The whole process took about 6 hours.
The invention of Neslar gave birth to numerous falsifications in the US up to 1915. That motivated him to open a beauty salon in New York and to re-patent the system, but this time improved and consistent with US law. In 1930 the inventor of Afro-American origin, Solomon Harper presented the first rollers without heating. Shortly after that, the first entirely plastic and still popular, hair curlers appeared.
Modern curlers are lighter and vary in shape, length and material, depending on the desired effect in the hairstyle. The wider the diameter of the rollers is, the greater the curls will be. And the shape of the curls changes depending on the way the rollers are placed. Some hair curlers should be worn overnight or for several hours, and other- for a very short time.
The selection of curlers is determined by the hair specifics. Specialists in hairdressing salons will surely know what type to use, but if you decide to buy a kit for home use, try different options until you achieve the desired effect.
