Hair is a protein filament that grows from the follicles found in the dermis. Hair is one of the hallmarks of mammals. The human body, regardless of the bare areas of the skin, is covered by a follicle that produces thick terminal and fine velvet hair. The most common interests in hair are focused on hair growth, hair type, and hair care, but hair is also an important biomaterial that mainly consists of proteins, especially alpha-keratin.
Attitudes to different hairs, such as hairstyle and hair removal, vary greatly in different cultures and historical periods, but are often used to indicate one's personal beliefs or social position, such as age, gender, or religion.

Ikhtisar
The word "hair" usually refers to two different structures:
- parts under the skin, called hair follicles, or, when pulled from the skin, a bulb. This organ is located in the dermis and retains stem cells, which not only regrow the hair after falling, but also recruited to regrow the skin after the wound.
- axis, which is a hard fibrous part that extends over the surface of the skin. The cross section of the hair shaft can be divided into three zones.
Hair fibers have a structure consisting of several layers, starting from the outside:
- the cuticle, consisting of several layers of flat, thin cells arranged overlap with each other as a shingle roof,
- the cortex, which contains the keratin bundle in a cell structure that remains rough like a stem.
- medulla, irregular and open area at the center of the fiber.

Description
Each strand of hair consists of medulla, cortex, and cuticle. The deepest region, the medulla, is not always present and is an open, unstructured area. The highly structural and organized cortex, or second of three layers of hair, is a major source of mechanical strength and water absorption. The cortex contains melanin, which dyes the fiber based on the amount, distribution and type of grains of melanin. The follicle shape determines the shape of the cortex, and its fiber shape is related to how straight or curly the hair is. People with straight hair have round hair fibers. The oval and other fibers are generally more wavy or curly. The cuticle is the outer cover. Its complex structure is gliding when hair swells and is covered with a single molecular layer that makes hair repel water. The diameter of a human hair varies from 0.017 to 0.18 millimeters (0.00067 to 0.00709 deep). There are two million small tubular glands and sweat glands that produce aqueous fluids that cool the body by evaporation. The glands in the opening of the hair produce a fatty secretion that lubricates the hair.
Hair growth begins inside the hair follicle. The only "live" part of the hair is found in the follicle. The visible hair is a hair shaft, which shows no biochemical activity and is considered "dead". The base of the hair root ("bulb") contains cells that produce hair shaft. Other structures of hair follicles include oils that produce sebaceous glands that lubricate the hair and pili arrector muscles, which are responsible for causing hair to stand. In humans with little body hair, the effect produces goose bumps.
Hair root
The hair root ends with enlargement, the hair bulb , which is whiter in color and softer in the texture of the stem, and lodged in the follicular involution of the epidermis is called the hair follicle. The bulb of the hair layer consists of fibrous connective tissue, glass membrane, external root sheath, internal root sheath consisting of epithelial layer (Henle layer) and granular layer (Huxley layer), cuticle, cortex and hair medulla.
Natural color
All natural hair color is the result of two types of hair pigment. Both of these pigments are a type of melanin, produced in hair follicles and packed into granules found in fibers. Eumelanin is the dominant pigment in brown hair and black hair, while pheomelanin is dominant in red hair. Blond hair is the result of having small pigmentation in hair strands. Gray hair occurs when melanin production decreases or stops, while polyuria is the hair (and often the skin attached to the hair), usually in spots, which never have melanin at all in the first place, or quit for natural genetic reasons , generally, in the first years of life.
Human hair growth
Hair grows everywhere in the external body except mucous membranes and bare skin, as found in the palms, soles of the feet, and lips.
Hair follows a specific growth cycle with three distinct and concurrent phases: anagen, catagen, and telogen phases; all three occur together - while one hair may be in anagen phase, the other may be in the telogen phase. Each has a special characteristic that determines the length of the hair.
The body has various hair types, including vellus hair and androgenic hair, each with its own cellular construction type. Different constructions provide unique hair characteristics, serve special purpose, especially, warmth and protection.
Texture
Hair is in various textures. The three main aspects of hair texture are curl pattern, volume, and consistency. Hair texture derivation is not fully understood. All mammalian hair is composed of keratin, so makeup hair follicles are not the source of various hair patterns. There are various theories relating to the pattern of hair curls. Scientists have believed that hair shaft forms have an effect on individual hair curls. A highly spherical axle allows less disulfide bonding to be present in the strands of hair. This means the bonds that are present are directly aligned with each other, producing straight hair.
The flatter hair shaft becomes, the more viscous the hair gets, because its shape allows more cysteines to be solidified together resulting in a bent shape which, with each additional disulfide bond, becomes more curlier in shape. Because the hair follicle shape determines the curling pattern, the size of the hair follicle determines the thickness. While the hair follicle circle expands, so does the thickness of the hair follicles. The volume of a person's hair, as a result, can be thin, normal, or thick. Hair consistency can almost be grouped into three categories: smooth, medium, and rough. This property is determined by the volume of hair follicles and the condition of the strand. Smooth hair has the smallest circumference, coarse hair has the largest circumference, and hair is being anywhere between the two others. Rough hair has a more open cuticle than a thin or medium hair that causes it to be the most porous.
System classification
There are various systems that people use to classify their curly patterns. Having knowledge of individual hair types is a good start to know how to take care of someone's hair. There is not only one method to find one's hair type. It is also possible, and it is normal to have more than one type of hair type, for example having a mixture of both 3a & amp; 3b curls.
- Andre Walker System
The Andre Walker Hair Typing System is the most widely used system to classify hair. This system was created by hairdresser Oprah Winfrey, Andre Walker. According to this system there are four types of hair: straight, wavy, curly, curly.
- Type 1 is straight hair, which reflects the most sparkling and also the toughest hair of all hair types. Difficult to damage and very difficult to roll this hair texture. Because sebum spreads easily from the scalp to the tip without curls or kinks to interfere with its pathway, it is the most oily hair texture.
- Type 2 is choppy hair, whose texture and radiance range between straight and curly hair. Wavy hair is also more likely to be curly than straight hair. While type A waves can easily alternate between straight and curly, B and C types Wavy hair is resistant to style.
- Type 3 is a curly hair known to have an S-shape. The curl pattern may resemble the "s", uppercase "S", or sometimes uppercase "Z" or lowercase "z". This type of hair is usually thick, "depending on climate (moisture = curling), and prone to damage." The lack of proper care causes less defined curls.
- Type 4 is curly hair, which has a tight circular curling pattern (or no visible curl pattern at all) that is often brittle with very high density. This type of hair shrinks when wet and because it has fewer cuticle layers than other hair types, these hairs are more susceptible to damage.
- FIA System
This is a method that classifies hair with curl patterns, hair strand thickness and overall hair volume.
Function
Many mammals have feathers and other hairs that work differently. Hair provides heat and camouflage settings for many animals; for others it gives signals to other animals such as warning, marriage, or other communicative display; and for some animal hair provides defense functions and, rarely, even offensive protection. Hair also has sensory function, extending the sense of touch beyond the skin surface. The hair guard gives a warning that can trigger an emptying reaction.
Warmth
While humans have developed clothing and other ways to keep warm, the hair found in the head serves primarily as a source of heat and cooling insulation (when sweat evaporates from wet hair) as well as protection from exposure to ultra-violet radiation. Hair function at other sites is debatable. Hats and coats are still needed during outdoor activities in cold weather to prevent frostbite and hypothermia, but the hair on the human body helps keep the internal temperature under control. When the body is too cold, the pili arrector muscle that is found attached to the hair follicle stands, causing hair in this follicle to do the same thing. These hairs then form a heat trap layer above the epidermis. The process is formally called piloerection, derived from the Latin word 'pilus' ('hair') and 'erectio' ('rose'), but more commonly known as 'have goosebumps' in English. This is more effective in other mammals whose feathers flils up to make air bags between the hair that protects the body from cold. The opposite action occurs when the body is too warm; the arrector muscles make the hair lying on the skin allowing the heat to go away.
Protection
In some mammals, such as hedgehogs and hedgehogs, hair has been modified into thorns or hard spines. It is covered with a thick keratin plate and serves as a protection against predators. Thick hair like a mane of grims and grizzly bears offers protection from physical damage such as bites and scratches.
Touch sensation
The shifting and vibration of the hair shaft is detected by the neural receptors of hair follicles and nerve receptors in the skin. Hair can sense air movement as well as touch by physical objects and they provide a sensory awareness of the presence of ectoparasites. Some strands of hair, like eyelashes, are very sensitive to the presence of potentially harmful material.
Eyebrows and eyelashes
Eyebrows provide moderate protection in the eyes of dirt, sweat and rain. They also play a key role in non-verbal communication by displaying emotions such as sadness, anger, shock and excitement. In many other mammals, they contain more, hairs like whiskers that act as tactile sensors.
Eyelashes grow on the edges of the eyelids and protect the eyes from impurities. Eyelashes for humans, camels, horses, ostriches etc, whiskers for cats; they get used to feeling when dirt, dust, or other potentially harmful objects are too close to the eye. The eyes are reflexively closed as a result of this sensation.
Evolution
Hair comes from the ancestors of mammals, synapses, about 300 million years ago. It is currently unknown at what stage synapses acquired the characteristics of mammals such as body hair and mammary glands, since fossils rarely provide direct evidence for soft tissue. The impression of the abdominal skin and the lower tail of the pelycosaur, possibly Haptodus shows the stock of the basal synapse synopsid bore across the rectangular line, similar to that of a modern crocodile. The very well-preserved skull of Estemmenosuchus, a therapsid of Upper Permian, shows smooth and hairless skin with what appears to be gland depression, although as semi-aquatic species may not be very useful. to determine the integument of terrestrial species. The undisputed oldest fossils that are known to show unambiguous hair trails are the Callovian (late Jurassic) Castorocauda and some haramiyidan and contemporary, both near mammal cammodonts. More recently, research at the Permian Russian coprolites terminal may indicate that the non-mammalian synapsids of that era have feathers. If this is the case, these are the remains of the oldest known hair, indicating that the feathers occur as far as the latest Paleozoikum.
Some modern mammals have special glands in front of each orbit used to offend feathers, called the hardened glands. Traces of this structure are found in small early mammal skeletons such as Morganucodon , but not in their cynodont ancestors such as Thrinaxodon .
The feathers in modern animals are all connected to the nerves, and the feathers also serve as transmitters for sensory input. Feathers can evolve from sensory hair (whiskers). The signals from this sensory device are interpreted in the neocortex, a brain chapter that develops significantly in animals such as Morganucodon and Hadrocodium . The more advanced therapsids can have a combination of bare skin, mustache, and scute. Full propellants may not evolve until therapsid-mammal transitions. The more advanced and smaller therapsids can have a combination of hair and scales, a combination still found in some modern mammals, such as rodents and opossums.
Do not have human hair
The loss of human hair in general compared to related species is probably due to loss of function in pseudogene KRTHAP1 (which helps produce keratin) in the human bloodline about 240,000 years ago. Individually, mutations in the HR gene can cause complete hair loss, although this is not typical in humans. Humans can also lose their hair due to hormonal imbalance due to drugs or pregnancy.
To understand why humans are essentially hairless, it is important to understand that mammalian body hair is not only aesthetic characteristics; protects the skin from wounds, bites, heat, cold, and UV radiation. In addition, it can be used as a communication tool and as a camouflage. For this purpose, it can be concluded that the benefits derived from loss of human body hair must be large enough to exceed the loss of these protective functions with nudity.
Humans are the only species of primate that has experienced significant hair loss and about 5000 species of mammal that still exist, only a handful that is effectively not hairy. The list includes elephants, rhinoceros, hippopotamus, walrus, several species of pigs, whales and other cetaceans, and naked mole rats. Most mammals have light skin covered with feathers, and biologists believe that ancestral human ancestors also began this way. Dark skin may evolve after humans lose their body hair, as bare skin is susceptible to strong UV radiation as described in the Out of Africa hypothesis. Therefore, evidence of time when human skin becomes dark has been used to date the loss of human body hair, assuming that dark skin is needed after the fur is gone. It is hoped that dating with the splitting of an ancestral human louse into two species, head lice and pubic lice, will date the loss of body hair on human ancestors. However, it turns out the human genital louse does not descend from the ancestral human lice, but from the gorilla louse, deviating 3.3 million years ago. This shows that humans have lost body hair (but still have head hair) and develop thick pubic hair before this date, living in or near the forest where the gorillas live, and obtaining pubic lice from gorillas that slaughter or sleep in their nests. The head lice evolution of head lice, on the other hand, puts the date of clothing much later, about 100,000 years ago.
Sweat glands in humans can evolve to spread from the hands and feet when body hair changes, or hair changes can occur to facilitate perspiration. Horses and humans are two of the few animals that are capable of sweating in most of their bodies, yet larger horses and still have fully developed feathers. In humans, the skin's hair lies flat in hot conditions, because the pull pili muscles relax, preventing heat trapped by the air layer between the hair, and increasing heat loss by convection.
Another hypothesis for thick body hair in humans suggests that the runaway sexual selection of Fisher plays a role (as well as in the selection of long head hair), (as well as the type of hair and vellus hair), and a much larger role of testosterone in men. Sexual selection is the only theory so far that explains the sexual dimorphism seen in male and female hair patterns. On average, men have more body hair than women. Men have more terminal hair, especially on face, chest, abdomen, and back, and women have more hair, less visible. Stopping hair growth in the adolescent stage, velus hair, will also be consistent with neoteny seen in humans, especially in women, and thus they can occur at the same time. This theory, however, has significant ownership in current cultural norms. There is no evidence that sexual selection will continue to a very drastic level more than a million years ago when a full and fertile hair is likely to indicate health and is therefore more likely to be chosen for for , not against , and not all human populations today have sexual dimorphism in body hair.
The next hypothesis is that human hair is reduced in response to ectoparasites. The explanation of "ectoparasites" about the nakedness of modern humans is based on the principle that hairless primates will have fewer parasites. When our ancestors adopted a group-living social arrangement of about 1.8 mya, the burden of ectoparasites increased dramatically. Early humans became the only one of the 193 primate species that have fleas, which can be attributed to the near-life arrangement of a large group of individuals. While primate species have communal sleeping arrangements, these groups are always on the move and thus tend to have no ectoparasites. Therefore, selection pressure for early humans will support the decline of body hair because those with thick coats will have more deadly ectoparasites and will have lower levels of fitness.
Another view was suggested by James Giles, who tried to explain impartiality as evolving from the relationship between mother and child, and as a consequence of bipedalism. Giles also connects romantic love with hairless hair.
Another hypothesis is that the use of fire by humans causes or initiates a reduction in human hair.
Evolutionary variation
Evolutionary biologists claim that the genus Homo appeared in East Africa about 2.5 million years ago. They are designing new hunting techniques. Higher protein diets lead to the evolution of larger body and brain sizes. Jablonski postulates that increasing body size, in conjunction with intensive hunting during the day at the equator, raises a greater need to quickly dispense heat. As a result, humans evolved the ability to sweat: a process facilitated by the loss of body hair. The main problem with this theory, however, is that it does not explain why men are bigger, hairier, and more active in hunting than women. The male-female size difference among other closely related primates is much greater than among humans, and therefore decreases during human evolution. Other primates have sweat glands in their human-functioning armpits, and thus the possibility that human sweat glands evolved from the same distribution, spread to more areas of the body, than occurred through the evolution of new traits. It is not known whether increased distribution of sweat glands occurs before, during, or after, changes in body hair, or even whether they are related developments. Horses are also sweaty, and they are bigger, hairier, and spend more energy flowing than human men, so there may be no connection between the ability to sweat and the fragility of humans.
Another factor in human evolution that also occurs in prehistoric times is the preference choice for neoteny, especially in women. The notion that adult humans exhibit certain traits (teenagers), is not revealed in great apes, about a century ago. Louis Bolk made a long list of such traits, and Stephen Jay Gould published a short list on Ontogeny and Phylogeny. In addition, paedomorphic characteristics in women are often recognized as desirable by men in developed countries. For example, vellus hair is a characteristic of teenagers. However, while men develop longer terminal hair, more rough, thicker, and darker through sexual differentiation, women do not, leaving their vellus hair visible.
Texture
Curly hair
Jablonski insists that head hair is evolutionarily advantageous for pre-humans to maintain because it protects the scalp as they walk upright in intense UV (equatorial) light. While some may argue that, by this logic, humans should also express furry shoulders because these body parts are suspected to be exposed to the same conditions, head protection, brain chairs that allow mankind to become one of the most successful species. on the planet (and also very vulnerable at birth) is arguably a more urgent problem (axillary hair in the armpit and crotch is also preserved as a sign of sexual maturity). Sometimes during the gradual process whereby Homo erectus begins the transition from the hairy skin to the bare skin expressed by Homo sapiens, the texture of hair is putatively gradually changed from straight hair (the condition of most mammals, including the closest cousin human) --chimpanzees) to Afro-textured or 'curly' hair (ie rolled tight). This argument assumes that curly hair is better in blocking the path of UV rays to the body relative to straight hair (curly or circular hair would be very beneficial for light-skinned hominids living on the equator).
This is evidenced by the findings of Iyengar (1998) that UV rays can enter the roots of human hair directly (and thus into the body through the skin) through the hair shaft. Specifically, the results of this study indicate that this phenomenon resembles a portion of light through a fiber-optic tube (which does not work as effectively as bent or sharply curved or curled). In this sense, when the hominids (ie Homo Erectus) gradually lose their straight body hair and thus expose the skin which initially pale under the feathers into the sun, straight hair will become an adaptive obligation. With reverse logic, then, as humans travel further from Africa and/or the equator, straight hair may (initially) evolve to aid the entry of UV rays into the body during the transition from UV-protected dark skin to more pale skin.
Some people believe that the shriveled hair that grows into a typical Afro formation will greatly reduce the ability of the head and the brain to become cold because although African hair is much denser than its counterparts in Europe, under intense sunlight, 'wool hats' the resulting hair like that would be detrimental. However, anthropologists such as Nina Jablonski opposed the debate about this hair texture. In particular, Jablonski's statement indicates that the adjective "wool" refers to Afro-hair is mistaken in the high heat insulation connotation of the true wool of the sheep. Conversely, the relatively rare Afro-hair density, combined with the chewy coils actually yields a vacuum-like structure that in turn, Jablonski argues, is more likely to facilitate an increase in the circulation of cold air to the scalp. Furthermore, wet Afro hair does not stick to the neck and scalp unless it is completely soaked and instead tends to maintain a basic springy swelling because it is less easy to respond to moisture and sweat than straight hair. In this case, such properties can increase comfort levels in intense equatorial climates over straight hair (which, on the other hand, tend to naturally fall in the ear and neck to levels that provide a slightly improved comfort level in cold climates relative to close hair circular).
Furthermore, some people interpret Charles Darwin's ideas which show that some traits, such as hair texture, are so arbitrary to human survival that the role of natural selection played is trivial. Therefore, they argue in favor of his suggestion that sexual selection may be responsible for these traits. However, the tendency toward "trivial adaptive" hair textures may be rooted in the assessment of certain cultural values ​​rather than objective logic. In this sense it is likely that the texture of hair may play a significant role adaptively can not be completely eliminated from consideration. In fact, while the sexual selection hypothesis can not be ruled out, the asymmetric distribution of this trait guarantees environmental influences. Specifically, if hair texture is merely the result of arbitrary human aesthetic preferences, one would expect that the global distribution of hair textures would be quite random. In contrast, Afro hair distribution is highly inclined towards the equator.
Furthermore, it should be noted that the most pervasive expression of hair texture can be found in sub-Saharan Africa; a region of the world that has abundant genetic and paleo-anthropological evidence, is a relatively new starting point (~ 200,000 years) for modern humanity. In fact, although genetic findings (Tishkoff, 2009) show that sub-Saharan Africa is the most genetically diverse group of continents on Earth, Afro-textured hair is approaching ubiquity in the region. This suggests a strong long-term selective pressure, which contrasts strongly with most of the sub-Saharan group genomes, leaving little room for genetic variation in the locus that determines. Such patterns, again, do not seem to support the sexual aesthetics of humans as the sole or primary cause of this distribution.
EDAR focus
A recent study has shown that the genetic pattern at the EDAR locus, a modern human genome region that contributes to hair texture variation among most individuals of East Asian descent, supports the hypothesis that straight hair (East Asia) may be developed in this. branch of the modern human lineage after the original expression of natural afro hair wrapped tightly. In particular, the relevant findings indicate that the EDAR mutation encoding coarse straight hair textures in East Asia is 'rough' appearing within the ~ 65,000 year period, which is the time frame that includes from the beginning of 'Out of Africa' migration to the present.
Disease
Ringworm is a fungal disease that targets the hairy skin.
Premature gray hair is another graying condition before the age of 20 in white, before 25 years in Asia, and before 30 years in Africa.
Hair care
Hair care involves hygiene and hair makeup including hair on scalp, face, genitalia and other body hair. Hair care routines differ according to individual culture and physical characteristics of a person's hair. Hair can be tinted, trimmed, shaved, picked, or thrown away with treatments such as waxing, sugaring, and threading.
The removal practice
Revocation is the removal of hair from the surface of the skin. This can be achieved through methods such as shaving. Feather shaving is the removal of all strands of hair, including parts of hair that have not yet left the follicle. A popular way to shave hair is through waxing.
Shave
Shaving is done with bladed instruments, such as razors. The blades are brought close to the skin and caressed over the hair in the desired area to cut the terminal hair and make the skin feel smooth. Depending on the growth rate, one can begin to feel the hair grow back within hours of shaving. This is especially evident in men who develop shadows five hours after shaving their faces. This new growth is called stump. The stump usually appears to grow back thicker because the hair is shaved blunt rather than tapered at the end, although the hair never really grows back thicker.
Waxing
Waxing involves the use of sticky wax and paper or fabric to pull hair from its roots. Waxing is an ideal hair removal technique to keep hair-free areas for long periods of time. It can take three to six weeks for the wax-painted hair to reappear. Hair in previously waxed areas is also known to grow back smoother and thinner, especially compared to hair that has been shaved with a razor.
Laser deletion
Laser hair removal is a cosmetic method in which a small laser beam selective heat pulse on dark target material in an area that causes hair growth without damaging skin tissue. This process is repeated several times for months to years with hair growing less frequently until it finally stops; this is used as a permanent solution for waxing or shaving. Laser removal is done in many clinics along with many products at home.
Cut and Cut
Because the hair on the head is usually longer than other body hair types, cut with scissors or scissors. People with longer hair will most often use scissors to cut their hair, while short hair is maintained using a trimmer. Depending on the desired length and overall hair health, periods without cutting or cutting hair may vary.
A haircut can be used in a wig. Global hair imports in 2010 are worth US $ 1.24 billion.
Social roles
Hair has a great social significance for humans. Can grow in most external areas of the human body, except in the palms of the hands and soles of the feet (among other areas). Hair is most visible to most people in a small area, which is also the most commonly trimmed, picked, or shaved part. These include the face, ears, head, eyebrows, legs, and armpits, as well as the pubic area. The highly visible difference between a man's and a woman's body and facial hair is a prominent secondary feature of sex.
The longest hair is documented in the world of Xie Qiuping (China), at 5.627 m (18 ft5.4 in) when measured on May 8, 2004. He has grown his hair since 1973, from the age of 13.
Status indication
Healthy hair shows health and youth (important in evolutionary biology). Hair color and texture can be a sign of ethnic ancestry. Facial hair is a sign of puberty in men. White hair is a sign of age or genetics, which may be disguised with hair dye (not easy for some), although many prefer to consider it (especially if it is a characteristic of poliosis since childhood). Male pattern baldness is a sign of age, which may be hidden by wigs, hats, or religious and cultural jewelry. Although medicines and medical procedures exist for the treatment of baldness, many bald men just shave their heads. In early modern China, the queue was a male hairstyle worn by Manchu from central Manchuria and Han Chinese during the Qing dynasty; the hair on the front of the head is shaved out above the temples every ten days, mimics male baldness, and the rest of the hair is braided into long pigtails.
Hairstyles can be an indicator of group membership. During the British Civil War, followers of Oliver Cromwell decided to cut their hair near their heads, as an act against the curls and curls of kings. This led to a Parliamentary fraction dubbed the Roundheads. Recent isotopic hair analyzes help explain more about sociocultural interactions, providing information on food procurement and consumption in the 19th century. Bob hair has been popular among flappers in the 1920s as a sign of rebellion against a traditional role for women. Female art students known as "cropheads" also adopted the style, especially at Slade School in London, England. Regional variations in hirsutism lead to the practice of hair on different arms and legs. Some religious groups may follow certain rules about hair as part of religious obedience. The rules are often different for men and women.
Many subcultures have hairstyles that can indicate unofficial membership. Many hippies, metalheads and Indian sadhu have long hair, as well as many older indie children. Many crooks wear hairstyles known as mohawk or other spiked and dyed hairstyles; skinheads have heads that are cut short or completely shaved. Long-style bangs are very common for emos, scene kids and young indie children in the 2000s and early 2010s, among people of both sexes.
Heads were shaved in concentration camps, and head shaving had been used as a punishment, especially for women with long hair. Shaved heads are common in military haircuts, while Western monks are known for their tone. Conversely, among some Indian saints, her hair is very long.
During Confucius (5th century BC), the Chinese grew his hair and often tied it, as a symbol of devotional devotion.
Regular hair stylist in some cultures is considered a sign of wealth or status. Rastafari movement gamal was humiliated at the beginning of the movement's history. In some cultures, cutting a person's hair can symbolize liberation from one's past, usually after trying time in one's life. Cutting hair can also be a sign of mourning.
Hair that is rolled tightly in its natural state can be used in Afro. This hair style has been used among African Americans as a symbol of racial pride. Given that the circular texture is a natural state of some African American hair, or considered more "African", this simple style is now often seen as a sign of self-acceptance and affirmation that the norms of beauty (eurocentris)) Dominant culture is not absolute. It is important to note that African Americans as a whole have a variety of hair textures, as they are not a homogeneous ethnic group, but ad-hoc from a mixture of different races.
The Easy Rider film (1969) included the assumption that the two main characters could have their long hair shaved with razor razors when imprisoned, symbolizing the intolerance of some conservative groups against members of the counter. At the end of Oz's obscenity test in Britain in 1971, the defendants had shaved their heads by the police, causing public outrage. During the appeal hearing, they appear on the dock wearing a wig. A case in which a 14-year-old student was expelled from school in Brazil in the mid-2000s, allegedly because of his mock haircut, sparked a national debate and legal action that resulted in compensation.
