A comb is a tool consisting of a shaft that holds a row of teeth for pulling through the hair to clean, untangle, or style it. Combs have been used since prehistoric times, having been discovered in very refined forms from settlements dating back to 5,000 years ago in Persia. [1]
Weaving combs made of whalebone dating to the middle and late Iron Age have been found on archaeological digs in Orkney and Somerset. [2]
Combs are made of a shaft and teeth that are placed at a perpendicular angle to the shaft. Combs can be made out of a number of materials, most commonly plastic, metal, or wood. In antiquity, horn and whalebone was sometimes used. Combs made from ivory [3] and tortoiseshell [4] were once common but concerns for the animals that produce them have reduced their usage. Wooden combs are largely made of boxwood, cherry wood, or other fine-grained wood. Good quality wooden combs are usually handmade and polished. [5]
Combs come in various shapes and sizes depending on what they are used for. A hairdressing comb may have a thin, tapered handle for parting hair and close teeth. Common hair combs usually have wider teeth halfway and finer teeth for the rest of the comb. [6] Hot combs were used solely for straightening hair during the colonial era in North America. [7]
A hairbrush comes in both manual and electric models. [8] It is larger than a comb, and is also commonly used for shaping, styling, and cleaning hair. [9] A combination comb and hairbrush was patented in the 19th century. [10]
Combs can be used for many purposes. Historically, their main purpose was securing long hair in place, decorating the hair, matting sections of hair for dreadlocks, or keeping a kippah or skullcap in place. In Spain, a peineta is a large decorative comb used to keep a mantilla in place. [5]
In industry and craft, combs are used in separating cotton fibres from seeds and other debris (the cotton gin, a mechanized version of the comb, is one of the machines that ushered in the Industrial Revolution). A comb is used to distribute colors in paper marbling to make the swirling colour patterns in comb-marbled paper. [11]
Combs are also a tool used by police investigators to collect hair and dandruff samples that can be used in ascertaining dead or living persons' identities, as well as their state of health and toxicological profiles. [12]
Sharing combs is a common cause of parasitic infections much like sharing a hat, as one user can leave a comb with eggs or live parasites, facilitating the transmission of lice, fleas, mites, fungi, and other undesirables. Siblings are also more likely to pass on nits to each other if they share a comb. [13]
Stringing a plant's leaf or a piece of paper over one side of the comb and humming with cropped lips on the opposite side dramatically increases the high-frequency harmonic content of the hum produced by the human voice box, and the resulting spread sound spectrum can be modulated by changing the resonating frequency of the oral cavity. [14] This was the inspiration for the kazoo, a membranophone.
The comb is also a lamellophone. Comb teeth have harmonic qualities of their own, determined by their shape, length, and material. A comb with teeth of unequal length, capable of producing different notes when picked, eventually evolved into the thumb piano [15] and music box. [16]
In China, combs are referred to by the generic term shubi (梳篦) or zhi (栉) and originated about 6000 years ago during the late Neolithic period. Chinese combs are referred as shu (梳) when referring to thick-tooth comb and bi (篦) when referred to thin-tooth comb. [17] A form of shubi produced in Changzhou is the Changzhou comb; the Palace Comb Factory, also called Changzhou combs Factory, found in the city of Changzhou started to operate since the 5th century and continues to produce handmade wooden combs up to this day. [5] : 87 Shubi were also introduced in Japan during the Nara period where they were referred by the generic name kushi. [18]
In Japan, combs are referred to as kushi. Indigenous Japanese kushi started to be used by Japanese people about 6000 years ago in the Jōmon era. In the Nara period, Chinese combs from the Tang dynasty were introduced in Japan. [18] Another form of comb in Japan is the Satsuma comb, which started to appear around the 17th century and was produced by the samurai warriors of the Satsuma clan as a side job. [19]
A liturgical comb is a decorated comb with used ceremonially in both Catholic and Orthodox Christianity during the Middle Ages, and in Byzantine Rite up to this day. [20]
Specialized combs such as "flea combs" or "nit combs" can be used to remove macroscopic parasites and cause them damage by combing. [21] A comb with teeth fine enough to remove nits is sometimes called a "fine-toothed comb", as in the metaphoric usage "go over [something] with a fine-toothed comb", meaning to search closely and in detail. Sometimes in this meaning, "fine-toothed comb" has been reanalysed as "fine toothcomb" and then shortened to "toothcomb", or changed into forms such as "the finest of toothcombs". [22] [23]
An Afro pick is a type of comb having long, thick teeth which is usually used on kinky or Afro-textured hair. It is longer and thinner than the typical comb, and it is sometimes worn in the hair. [24] [25]
The history of the Afro pick dates back at least 5,000 years, as a practical tool that may also have cultural and political meaning. [26]
An unbreakable plastic comb is a comb that, despite being made of plastic rather than (more expensive) metal, does not shatter into multiple pieces if dropped on a hard surface such as bathroom tiles, a hardwood floor, or pavement. [27] Such combs were introduced in the mid-twentieth century. [28] Today most plastic combs are unbreakable as technology has reached a point of understanding the causation of brittleness in these products. [29]
Modern artisan combs crafted from a wide variety of new and recycled materials have become popular over recent years. Used skateboard decks, vinyl records, [30] brass, titanium alloy, acrylic, sterling silver, and exotic wood are a few of the materials being used.
A hairstyle, hairdo, haircut or coiffure refers to the styling of hair, usually on the human head but sometimes on the face or body. The fashioning of hair can be considered an aspect of personal grooming, fashion, and cosmetics, although practical, cultural, and popular considerations also influence some hairstyles.
A toothbrush is an oral hygiene tool used to clean the teeth, gums, and tongue. It consists of a head of tightly clustered bristles, atop of which toothpaste can be applied, mounted on a handle which facilitates the cleaning of hard-to-reach areas of the mouth. They should be used in conjunction with something to clean between the teeth where the bristles of the toothbrush cannot reach - for example floss, tape or interdental brushes.
Pediculosis is an infestation of lice from the sub-order Anoplura, family Pediculidae. Accordingly, the infestation with head lice is named pediculosis capitis, while this with body lice, pediculosis corporis. Although pediculosis in humans may properly refer to lice infestation of any part of the body, the term is sometimes used loosely to refer to pediculosis capitis, the infestation of the human head with the specific head louse.
A saw is a tool consisting of a tough blade, wire, or chain with a hard toothed edge used to cut through material. Various terms are used to describe toothed and abrasive saws.
Pottery and porcelain is one of the oldest Japanese crafts and art forms, dating back to the Neolithic period. Types have included earthenware, pottery, stoneware, porcelain, and blue-and-white ware. Japan has an exceptionally long and successful history of ceramic production. Earthenwares were made as early as the Jōmon period, giving Japan one of the oldest ceramic traditions in the world. Japan is further distinguished by the unusual esteem that ceramics hold within its artistic tradition, owing to the enduring popularity of the tea ceremony.
Geta (下駄) are traditional Japanese footwear resembling flip-flops. A kind of sandal, geta have a flat wooden base elevated with up to three "teeth", held on the foot with a fabric thong, which keeps the foot raised above the ground.
A file is a tool used to remove fine amounts of material from a workpiece. It is common in woodworking, metalworking, and other similar trade and hobby tasks. Most are hand tools, made of a case hardened steel bar of rectangular, square, triangular, or round cross-section, with one or more surfaces cut with sharp, generally parallel teeth. A narrow, pointed tang is common at one end, to which a handle may be fitted.
A hairbrush is a brush with rigid or light and soft spokes used in hair care for smoothing, styling, and detangling human hair, or for grooming an animal's fur. It can also be used for styling in combination with a curling iron or hair dryer.
A hair dryer, hairdryer, hairdrier, or blow dryer is an electromechanical device that blows ambient or hot air over damp hair to speed the evaporation of water to dry the hair. Blow dryers enable better control over the shape and style of hair, by accelerating and controlling the formation of temporary hydrogen bonds within each strand. These bonds are powerful but are temporary and extremely vulnerable to humidity. They disappear with a single washing of the hair.
Kanzashi are hair ornaments used in traditional Japanese hairstyles. The term kanzashi refers to a wide variety of accessories, including long, rigid hairpins, barrettes, fabric flowers and fabric hair ties.
The treatment of human lice is the removal of head lice parasites from human hair. It has been debated and studied for centuries. However, the number of cases of human louse infestations has increased worldwide since the mid-1960s, reaching hundreds of millions annually. There is no product or method that assures 100% destruction of the eggs and hatched lice after a single treatment. However, there are a number of treatment modalities that can be employed with varying degrees of success. These methods include chemical treatments, natural products, combs, shaving, hot air, and silicone-based lotions.
A headband or hairband is a clothing accessory worn in the hair or around the forehead, usually to hold hair away from the face or eyes. Headbands generally consist of a loop of elastic material or a horseshoe-shaped piece of flexible plastic or metal. They come in assorted shapes and sizes and are used for both fashion and practical or utilitarian purposes.
Head lice infestation, also known as pediculosis capitis, is the infection of the head hair and scalp by the head louse. Itching from lice bites is common. During a person's first infection, the itch may not develop for up to six weeks. If a person is infected again, symptoms may begin much more quickly. The itch may cause problems with sleeping. Generally, however, it is not a serious condition. While head lice appear to spread some other diseases in Africa, they do not appear to do so in Europe or North America.
A toothcomb is a dental structure found in some mammals, comprising a group of front teeth arranged in a manner that facilitates grooming, similar to a hair comb. The toothcomb occurs in lemuriform primates, treeshrews, colugos, hyraxes, and some African antelopes. The structures evolved independently in different types of mammals through convergent evolution and vary both in dental composition and structure. In most mammals the comb is formed by a group of teeth with fine spaces between them. The toothcombs in most mammals include incisors only, while in lemuriform primates they include incisors and canine teeth that tilt forward at the front of the lower jaw, followed by a canine-shaped first premolar. The toothcombs of colugos and hyraxes take a different form with the individual incisors being serrated, providing multiple tines per tooth.
Hairstyling tools may include hair irons, hair dryers, hairbrushes, hair rollers, diffusers and various types of scissors.
Pediculosis pubis is an infestation by the pubic louse, Pthirus pubis, a wingless insect which feeds on blood and lays its eggs (nits) on mainly pubic hair. Less commonly, hair near the anus, armpit, beard, eyebrows, moustache, and eyelashes may be involved. It is usually acquired during sex, but can be spread via bedding, clothing and towels, and is more common in crowded conditions where there is close contact between people.
The Changzhou comb is a type of hand-painted comb produced in Changzhou, Jiangsu, China. In China, combs are called shubi (梳篦). The combs were originally made for use by royalty and have been in production for over 2000 years.
The sublingua ("under-tongue") is a muscular secondary tongue found below the primary tongue in tarsiers and living strepsirrhine primates, which includes lemurs and lorisoids. Although it is most fully developed in these primates, similar structures can be found in some other mammals, such as marsupials, treeshrews, and colugos. This "second tongue" lacks taste buds, and in lemuriforms, it is thought to be used to remove hair and other debris from the toothcomb, a specialized dental structure used to comb the fur during oral grooming.
According to the Mahāparinibbāṇa Sutta, after attaining parinirvana, the body of Buddha was cremated and the ashes divided among his lay followers.
Shubi, also called as zhi, is a generic term used for Chinese combs in China, which includes thick-teeth comb shu and thin-teeth comb bi. Shubi originated about 6000 years ago in China during the late Neolithic period. Some Chinese combs dating from the Shang dynasty were found in the Tomb of Fuhao. In ancient China, Chinese combs had a high special status, a high artistic value, was an important form of hair ornament in Chinese history. Chinese comb also had and continues to hold unique cultural meaning and emotional value. Chinese combs in China were not used only for grooming purposes, they were also used holding and decorating hair. Both Chinese men and women wore decorative combs in their hair in ancient China. Chinese women often wore combs and fine-tooth combs in their hair buns. Chinese comb-making was also an important form of traditional Chinese art and business industry.
