A modern plastic comb.

A comb is a toothed device used for styling, cleaning and managing hair and scalp. Combs are among the oldest tools found by archaeologists,[1] having been discovered in very refined forms from settlements dating back to 5,000 years ago in Persia.[2]

Description

Combs consist 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. Combs made from ivory[3] and tortoiseshell[4] were once common but concerns for the animals that produce them have reduced their usage. When made from wood, combs are largely made of boxwood, cherry wood or other fine-grained wood. Good quality wooden combs are usually handmade and polished.[5]

Combs can vary in shape according to function. Hairdressing combs may have a thin, tapered handle for parting hair and close teeth. Common hair combs usually have wider teeth half way 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, is also commonly used for shaping, styling and cleaning hair.[9] A combination comb and hairbrush was patented in the 19th century.[10]

Uses and types

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 locking; or keeping a kippah or skullcap in place. In Spain, a peineta is a large decorative comb to keep a mantilla in place.[11][12]

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 the Industrial Revolution). A comb is used to distribute colours in paper marbling to make the swirling colour patterns in comb-marbled paper.[13]

Combs are also a favorite spot for 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, toxicological profiles, and so forth.[14]

Making music

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.[15]

This was the inspiration for the kazoo. Moreover, 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[16] and musical box.[17]

Afro pick

This type of comb has loose teeth and is usually used on kinky or Afro-textured hair. It is sometimes worn in the hair.[18][19]

Nit comb

A Stone Age nit comb.

Specialized combs such as "flea combs" or "nit combs" can be used to remove macroscopic parasites and cause them damage by combing.[20] 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 "search [something] 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".[21]

Hygiene

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 so it is advisable to buy each separate child their own comb.[22]

Unbreakable plastic comb

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 a pavement.[23] Such combs were introduced in the middle of the twentieth century.[24] Today most plastic combs are unbreakable as technology has reached a point of understanding the causation of brittleness in these products.[25]
