Comb

, Kerala 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 and tortoiseshell 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. 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. Hot combs were used solely for straightening hair during the colonial era in North America. A hairbrush comes in both manual and electric models. It is larger than a comb, and is also commonly used for shaping, styling, and cleaning hair. A combination comb and hairbrush was patented in the 19th century. ==Uses ==

– Woman Combing Her Hair (1865) 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. 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. Hygiene Sharing combs is a common cause of parasitic or lice 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. 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. 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 and music box. == Types ==
