Best hair color is the pigmentation of hair follicles due to two types of melanin: EUMELANIN and pheomelanin. In general, if there is more EUMELANIN blonde hair colorsr is darker; if there is les EUMELANIN, hair is lighter. Levels of melanin can vary over time causing a person blonde hair colorsr to change, and it is posible that the hair follicles have more than one color to the same person.Special hair dyes are asociated with ethnic groups. The shades of human brown hair colorr was evaluated by Fischer-SALLER scale. Fischer-SALLER scale, named after Eugen Fischer and Karl Saller, which is used in physical anthropology and medicine to determine the shades of blonde hair colorsr. The scale uses the following indications: (light blonde) B to E (blond), F L (blond) M to O (dark blond), P, T (brown), U to Z (dark brown / black) and Roman numbers I to IV (red) and V to VI (red blonde). See also Martin Schultz scale for eye color. Genetics and Biochemistry blonde hair colorsr Two types of pigment gives best hair colorr: EUMELANIN and pheomelanin. Pheomelanin best hair colorr orange and yellow. All people have some pheomelanin in their hair. EUMELANIN, which has two subtypes black or brown, best hair colorr determines the darknes. A low concentration of brown EUMELANIN results in blond hair, whereas the higher concentration of brown EUMELANIN stained brown hair. High amounts of black EUMELANIN result in black hair, while low concentrations cause gray hair.Pheomelanin is more chemically stable than black EUMELANIN, but les chemically stable than brown EUMELANIN, so it breaks down more slowly when oksidira.To is why bleach gives darker hair reddish hue of the artificial coloring proces. As the pheomelanin has broken down, the hair will gradually orange, then yellow, and finally white.Genetics best hair colorr are not yet firmly anchored. According to one theory, at least two pairs of control gene of human brown hair colorr.One phenotype (brown / blonde) has a dominant brown allele and a recesive blonde allele. A person with a brown allele will have brown hair; a person with no brown alleles will be blond. This explains why two brown-haired parents produce blond hair child. However, this can only be posible if both parents are heterozygous in the best hair colorr which means that they both have one dominant allele brown hair and one recesive allele of blonde hair, but as always dominant win both parents have brown hair. The punnet square is posible to determine the posibility of a particular trait in the offspring.The other gene pair of non-red / red pair, wherein the non-red allele (which inhibits the formation of pheomelanin) and the dominant allele for red hair is recesive. A person with two copies of the red-haired allele will have red hair.Model two gene does not consider all the posible shades of brown, blond or red (for example, platinum blond versus dark blonde / light brown), nor does it explain why brown hair colorr sometimes darkens as a person ages. Several pairs of genes control the light versus dark brown hair colorr in a cumulative effect.The genotype of a person for multifactorial trait can interact with the environment to produce different phenotypes (see quantitative trait locus).Natural blonde hair colorsr Natural blonde hair colorsr can be black, brown, blond, red or white. Black Hair Black hair is the darkest color. It has a large amount of EUMELANIN and is les dense than other brown hair colorrs. This can range from brown-black, blue-black or jet-black. (Edit) Brown hairBrown hair is characterized by higher levels of EUMELANIN and lower levels of pheomelanin. Of the two types of EUMELANIN (black and brown), brown hair people have brown EUMELANIN; but also usually they have a medium-thick strands of hair. Brown-haired girls or women are often known as brunettes. Blond HairBlond (or blond) hair ranges from nearly white (platinum blond strands of hair) on a dark goldgolden blond. Strawberry blond, a mixture of blond and red hair is much rarer species, which contains more than pheomelanin.Blond hair can be almost any proportion of pheomelanin and EUMELANIN, but only a small amount of both. More pheomelanin creates more goldgolden blond color and more EUMELANIN creates ash blond. Many children born with blond hair develop darker hair as they age, while most developing natural blonds best hair colorr in the dark "gunmetal" shade by the time they reach middle age. Pregnancy hormones speed up this proces. Natural blond hair is rare in adulthood, with some reports indicating that only about 2% of the world population naturally blond.Blond hair is most commonly found in the northern and western Europeans and their descendants, but can be found spread acros much of Europe. Blond hair is rare outside of Europe, but can also be found in populations in South America and Avstraliji.Raziskave in 2012 it showed that naturally blond hair Melanesians cause recesive mutation in the tyrosinase-related protein 1 (TYRP1). In the Solomon Islands, 26% of the population carry the gene; However, absent outside of Oceania.Auburn Hair Auburn hair is moved along the spectrum of light to dark red-brown shades. Chemicals that cause Auburn hair are EUMELANIN (brown) and pheomelanin (red), with a higher proportion of red caused by pheomelanin, as found in a typical brown hair. It is most often found in individuals from Northern and Western European origin.Chestnut Hair Chestnut hair best hair colorr is reddish shade brown hair. In contrast to Auburn hair, a reddish chestnut shade is darker. Chestnut hair is common among native peoples of North, Central, Western and Eastern Europe. Red HairRed hair ranges from light strawberry blond shades to Tiziana, copper and les often "true" red. This causes changes in gene Mc1r and is recesive. Red hair has the highest amounts of pheomelanin, around 67%, and generally low levels of EUMELANIN. 1-2% of the population, is the least common brown hair colorr in the world. It is found most prominently in Scotland, Ireland and England.Scotland has the highest proportion of redheads; 13 percent of the population has red hair and approximately 40 percent carries the recesive redhead gene. Gray and white hair Gray or white blonde hair colorsr dialog sometimes called "salt and pepper" when it is "seasoned" acros the dark hair that really gray or white pigment does not cause, but due to lack of pigmentation and melanin. Clear coat appear as gray or white because of the way light is reflected from the hair. Grey brown hair colorr typically occurs naturally with age (see "Aging or achromotrichia" below). For some people this can happen in a very young age (for example, at the age of 10). The same is true for children with white hair, caused by albinism.In some cases, gray hair is caused by deficiency of the thyroid, Waardenburg syndrome, or vitamin B12 deficiency. At some point in the life cycle of human cells, which are located in the base of hair follicles slow and eventually stop producing pigment. Piebaldism is a rare autosomal dominant disorder is the development of melanocytes, which can cause congenital white plug.White people will start off in their twenties and early thirties, while Asian people start graying in their late thirties, but the majority of African people keep their original blonde hair colorsr until their mid-forties. People with albinism have white hair may be due to the low amounts of melanin. Conditions affecting brown hair colorr Aging or achromotrichiaChildren born with certain hair dyes may find it gradually darkens as they grow. Many blond, light brown or red hair babies to experience it. This is due to genes is turned off and in early childhood and puberty.Changes in blonde hair colorsr typically occur naturally with age, eventually changing hair gray and then white barve.To called achromotrichia. Achromotrichia usually begins in early to mid-twenties in men and women in their late twenties. More than 60 percent of Americans have some gray hair by age 40. The age at which graying begins seems to be almost entirely due to genetics. Sometimes people are born with gray hair because they inherited the trait.The order in which the graying occurs, it is usually: nose hair, the hair on the head, beard, body hair, eyebrows.It seems to be responsible for the aging proces of the two gene BCL 2 and Bcl-w is a change in blonde hair colorsr when melanin ceases to be produced in the hair root and new hairs grow in without pigment. Stem cells are at the bottom of the hair follicles producing melanocytes, the cells that produce and store pigment in hair and skin. Death of melanocyte stem cells cause aging. It is still unclear why the stem cells may one hair follicle also die more than a decade before those in neighboring follicles les than a millimeter apart.Hair graying can be triggered by the accumulation of hydrogen peroxide.Abnormally low levels of the enzyme catalase, which breaks down hydrogen peroxide and relieves oxidative stres in patients suffering from vitiligo. Since vitiligo can cause eyelashes to turn white, the same procedure believed to be involved in the hair on his head (and elsewhere) as a result of aging.Imatinib anticancer drugs recently shown to reverse the proces of aging. However, it is too expensive and can have a serious and deadly side effects, so that it is not practical to be used for changing the color of the person las.Vendar if it can detect the mechanism of action of imatinib on melanocyte stem cells, it is posible to be used to develop a safer and les expensive substitute drugs. It is not yet known whether the imatinib effect on catalase, or if the reverse the proces of aging due to something else. StresAnecdotes report that stres, both chronic and acute, may cause achromotrichia earlier in people than it would otherwise have had. Proponents point to the survivors of disasters such as Titanic survivor Harold Bride, or high-level politicians such as Bill Clinton and Barack Obama to support this view. There is some evidence of chronic stres causes premature achromotrichia, but no definite link has been established. It is known that the stres hormone cortisol accumulates in human hair ahead of time, but whether it affects brown hair colorr has not yet been resolved.Medical conditions Albinism is a genetic abnormality in which it found little or no pigment in human hair, eyes and skin.Hair is often white or pale blond. However, it may be red, dark blond, light brown, or rarely, even dark brown.Vitiligo is the patchy los of hair and skin color that may occur as the result of an autoimmune disease. In the previous study, in 2013, researchers addresed accumulation of hydrogen peroxide, which causes this light activates the pseudo-catalase. This produces significant media coverage that further investigation someday lead to an overall treatment of non-dye the gray hair.Malnutrition is also known to cause hair becomes lighter, thinner and more fragile. Dark hair may turn reddish or blondish due to the decrease in production melanina.Pogoj is reversible with proper nutrition.Werner syndrome and pernicious anemia can also cause premature aging.2005 uncontrolled study found that people 50-70 years of age with dark eyebrows but gray hair is much more likely to have type II diabetes than those with both gray eyebrows and hair. Artificial factors1996 Study of the British Medical Journal shows that smoking tobacco could cause premature aging. Smokers were found to be four times more likely to begin graying prematurely, compared to nonsmokers.Gray hair may temporarily darken after inflammatory proceses, after electron-beam-induced alopecia, and some chemotherapy regimens. Much remains to be learned about the physiology of human aging.There are no special diets, nutritional supplements, vitamins, nor proteins that have been shown to slow down, stop, or in any way affect the graying proces, although many were marketed in recent years. However, French scientists treat patients with leukemia with a new cure for cancer noted an unexpected side effect: some hair dyes patient was restored to their pre-gray. Changes after deathHair color mummies or buried bodies can be changed. Hair contains a mixture of black and brown and yellow and red EUMELANIN pheomelanin. EUMELANIN is les chemically stable than pheomelanin and breaks down faster when oxidized. It is for this reason that the Egyptian mummies reddish hair. Hair color changing faster in extreme conditions. This is changing slowly in dry conditions oxidants (such as, for example, in the graves in the sand or ice), as in the wet reducing conditions (such as funerals of wood or plaster coffins). best hair colorring Hair color can be changed by a chemical proces. Hair coloring is clasified as "permanent" or "semi-permanent".Permanent best hair colorr means that the structure of the hair is chemically changed until the end of the cut. This does not mean that the synthetic color remains permanent. During the proces, the natural color remove one or more shades and synthetic color is put in its place. All pigments wash off with cuticle.Natural color stays in a lot longer and fade the fastest man-made (depending on the color and shape of the molecules of pigments for coloring)Permanent brown hair colorr gives maximum flexibility, since they can hair lighter or darker, as well as modifying the tone and color, but there are negatives. Continuous (monthly or six-weekly) maintenance is esential to match the new hair growing in the rest of the hair, and the elimination of disappearing. Monochrome permanent dye creates a flat, uniform color throughout the head, which can look unnatural and harsh, especially in a fair shade. To combat this, the modern trend is to use more colors - usually one color as base with added highlights or lowlights in other colors.Semi-permanent color washes over a period of time - usually four to six weeks, so root regrowth is les noticeable. The final color of each strand depends on its original color and porosity, so the subtle variations in color over your head - a more natural and les harsh than a permanent dye. This means that the gray-white hair will not dye to the same color as the rest of the head (in fact, some white hair does not absorb any color) .Nekaj gray and white hairs blend sufficiently, it is not noticeable, but they have become more widespread, it will come to the point where semi-permanent in itself will not be enough. The transition to 100% permanent color can be delayed by using the semi-permanent as a base color with highlights ongoing.Semi-permanent best hair colorr can not lighten hair. Hair can be mitigated only by the use of chemical lighteners such as bleach. Bleaching is always constant because it removes the natural pigment."Purging" are a form of temporary blonde hair colors r is typically used for hair to shampoo and rinse again the next time the hair is washed. Black hair is the darkest and most common of all colors human hair world. It is a dominant genetic trait, and this can be found in people of all backgrounds and nationalities. It has a large amount of EUMELANIN and is les dense than other brown hair colorrs. Sometimes very dark brown (black, brown) hair is mistaken for black. In English, the black hair is sometimes described as "soft-black", "black raven" or "jet-black". The range of skin colors asociated with black hair is big, from the palest white skin tones on black skin. Black-haired people may have dark or bright eyes. Distribution Outside Europe, most people have black hair. This is probably the original brown hair color r Homo sapiens, and in its largest distribution in Africa, Asia, and pre-Columbian America. Black hair is particularly common in humans Asia, southern Europe and parts of South America and Africa, irrespective of ethnolinguistic affiliation. This is mainly concentrated among the Celtic peoples of Europe. For example, the west of Ireland is particularly known for their curly hair, very dark brown to jet-black hair in combination with either dark (such as brown) or light (such as green, gray or blue) colored eyes. Irish people with these characteristics are sometimes known as "Black Irish". Although this feature can be seen in people acros the UK to become more common in parts of central, southern and eastern Europe in particular.Dark hair people, ranging from dark brown and deep brown to black in color, or dark or light colored eyes can be seen between Indo-European and non-Indo-European ethnic groups in Iran, Caucasus, Central Asia, Afghanistan, and Northern India. Black hair is the least frequent in the Baltic coast, which is really blond hair is believed to have originated. Brown hair is the second most common human best hair color, the black hair. This varies from light brown to almost black hair. It is characterized by higher levels of the dark pigment EUMELANIN and lower levels of the pale pigment pheomelanin. Its strands are thicker than those of fair hair, but not as much as those red hair. Girls and women with brown or black hair is often referred to as a brunette, which in French is a feminine form of Brunet, who is diminutive beams (brown, brown-haired or dark-haired).Brown hair is common among the population in the Western world, especially among those from Central Europe, Southern Europe, the United States and some populations in the broader Middle East, where it transitions smoothly to black hair. Brown hair is common among Australian Aborigines and Melanesians. Etymology and grammarBrunette literally means "little brown-haired girl" or "young brown-haired woman," but in modern English usage, losing diminutive meaning and usually refers to any brown or black-haired girl, or woman, or related brown hair colorr. Merriam-Webster defines "Brunet" as "a person who has brown or black hair" -with which can be a "relatively dark complexion, written Brunet, when applied to a boyfriend or husband, and usually brunettes, when applied to a girl or a woman. "Although Brunet\'s version of the popular men\'s diminutive format that is used to describe a boy or young man, with brown hair, Brunet use is rare in English. One is more likely to say that a man or boy, "He has brown hair" or "He\'s a brown-haired", as he says, "He\'s a brunette" (or Brunet) .Izraz brunette is the feminine form of the French word Brunet, who Brun is a diminutive form meaning "brown / brown-haired", the woman he beams. All of these conditions ultimately derived from the Proto-Indo-European root * bhrn- \'brown, gray. " The form "logs" (pronounced / Brun /) is still widely used in Scotland, especially in rural areas.Lighthter or darker shades of brown hair may be referred to as the "brunette bright" or "dark brunette", although in such cases, one generally refers only to brown hair colorr, do not use the term as a metaphor for the person; one would be likely to say: "She is bright brunette." Instead, you could say: "She has light brown hair."Geographical distribution Brown-haired individuals are present throughout Europe. In the northern part of Central Europe, and medium to light brown shades are the most common, while darker tones dominate the rest of the continent, such as the Iberian Peninsula, where the transition to black hair. Brown hair, mainly medium to light brown shades, they are also dominant in Australia, Canada and the United States among descendants of northern, central and eastern Europe (British, German, Scandinavian, Polish and Rusian) immigrants.Like the blonde hair, brown hair, usually appears between the Australian Aborigine and Melanesian population.Dark brown hair is dominant in Latin America and the Middle East. BiochemistryPigment EUMELANIN gives brown hair its distinctive color. Brown hair has more EUMELANIN as blond hair, but is also much les than rna.Obstajata EUMELANIN two types, which differ from one another by their pattern of polymer bonds. Both are black and brown EUMELANIN EUMELANIN. Black EUMELANIN is the darkest; Brown EUMELANIN is much easier than black. Black EUMELANIN prevalent in non-Europeans, while brown EUMELANIN is mostly present in Europeans and non-Semitic people of the Middle East, and is rarely found in people of other nationalities. A small amount of black EUMELANIN in the absence of other pigments causes gray hair. A small amount of brown EUMELANIN in the absence of other pigments causes yellow (blond) color hair. Often, naturally blond or red hair darkens to brown color over time. Brown-haired people have medium-thick strands of hair.Brown-haired people are thought to produce more skin-protecting EUMELANIN and are asociated with a more even complexion. The range of skin colors asociated with brown hair is big, from the palest skin tones to olive complexion. Brunettes can be dark or light eyes. Varieties brown hairBrown hair comes in various shades from very darkest brown (almost black) to light brown shows slight signs of blondism.Shades of brown hair include: deepest brunette: the darkest brown color, which can be very dark chestnut; Sometimes, it appears that the black start distance. dark brown milk chocolate brown dark chestnut brown light chestnut medium brown: Standard brunette comparable to Ruset_ (color) Brown Walnut Brown: warmer variant medium brown, comparable with a light chestnut medium goldgolden brown: brown with yellowish ton.svetlo goldgolden brown light ash brown: almost blond hair lightest brown: light brown to blonde comes in the middle of the sun maple brown: dark goldgolden brown, like maple syrup cinnamon brown: light reddish brown color lighter than Auburn chestnut brown: reddish brown color darker than light brown bordo: dark brown with a deep reddish hue Culture Cultural connotationsIn western popular culture, a common stereotype is that brunettes stable, serious, smart and sophisticated. A British study into best hair color r and the intensity of attraction showed that 62 percent of the men participating in the study related brown-haired woman with the stability and capacity. Brunettes were described as independent and self-sufficient for 67 per cent of men and 81 percent for the intelligent. According to Allure magazine, in 2005, 76 percent of American women believed to have first woman president of the United States of brown hair. Modern fictionAnita Loos, author of the novel and the play Gentlemen Prefer Blondes, wrote a continued entitled A Gentlemen Marry brunette. Film about was done, gentlemen Marry brunettes, starring Jane Rusell and Jeanne Crain. Art and fictionLady of Shalott by Lord Tennyson poem is depicted as a brunette in most images. Leonardo Da Vinci\'s most famous painting Mona Lisa is also a brunette. In the French folk song "Au Clair de la Lune" cute brunette Lubin visited their neighbor to the proposal Pierrot is. In the Irish song "Star County Down" the narrator falls in love with a woman with "nut-brown" hair, which is called Rose McCann.Doktor, the eponymous character of a doctor who is able to regenerate his body and has brown hair in seven of its incarnations, including the first three doctors who have appeared in the revived series. Rivalry with blondesIn popular culture, it may appear as a brunette in rivalry or competition with a blonde woman. Rivalry may take the form of competitive sport or as part of a love triangle in which a blonde and brunette woman compete for the affection of man. Blond hair color is the hair color characterized by low levels of the dark pigment EUMELANIN. The resultant visible hue depends on various factors, but always has a yellow color. The color can range from very light blonde (with patchy, scarce distribution of pigment-induced) to reddish "strawberry" blond colors or goldgolden-brown ("sand"), blond color (the latter with more EUMELANIN). In the Fischer-SALLER comprises blond color ranges from A to J (blond brown) in. Etymology, spelling and grammar The word "blonde" is the first confirmed in English in 1481 and comes from the old French blund, blont meaning "middle color between goldgold and light brown \'. This gradually eclipsed by native term "fair" in the same sense from the old English fer, causing a "fair" later became a generic term for "light-complexioned". This prior use "fair" survives in its own name Fairfax, from Old English fer-feahs means "blonde hair".The French (and thus also in English) word "blonde" has two posible origins. Some linguists say that originates from medieval Latin blundus, which means "yellow", from Old Frankish blund that could relate to the Old English-blond feax means "gray-haired" from blondan / blandan meaning "mixed" (cf. mixture ). Even the old English beblonden mean "colored" as they were found an old Germanic warriors dying their hair.However, linguists favoring Latin origin of the word to say that the medieval Latin blundus vulgar pronunciation of Latin flavus, also means yellow. Most authorities, particularly the French, confirm the origin frankovski.Beseda was again in the English language in the 17th century from the French, and it was some time during the French; in French, "blond" is female adjective; He describes a woman with blond hair."Blond", with its further use-differed between the sexes, is one of the few adjectives in written English, feeding separate male and female grammatical genders. Each of the two formats, and is pronounced the same. The American Heritage Book of Angleina Usage propounds that as far as "blonde" is used to describe a woman rather than a man who has just said that the blond (e) the hair, such as the term is "sexist stereotype [which] are women primarily defined by their physical properties. "Oxford English Dictionary (OED) found that the term" big blond beast "used in the 20th century, specifically relating to men \'Nordic type" (ie, blond hair). In Oed also records Blond as an adjective applies with particular reference to women, in which case it is likely to be spelled "blonde", citing three Victorian usage of the term. The men\'s version is used to describe the amount in the "blonds European race" in the quote from the 1833 Penny cyclopedia that distinguishes genuine blondnes as Caucasian function differs from albinism.In the early 1990s, "blonde moment" or "dumb blonde", came in everyday language means "an instance of a person, esp. Women\'s silly ... but scatter-brained." Another blonde hair colorsr word of French origin, Brunet (te) (from the same Germanic root that has given "brown"), operates in the same way in orthodox angleini.OED gives "Brunet" in the sense of "dark-complexioned" or " dark-complexioned person, "the comparative use of Brunet and blond Thomas Henry Huxley, if I say" present contrast blonds and brunets existed between them. " You can "Brunette" is used, however, as the "blond", which describes the people of mixed gender. OED cites Grant Allen, "a nation that is being led ... sometimes blonde, sometimes brunette.""Blond" and "blond" are also sometimes used to refer to objects that have a color reminiscent of fair hair. Examples include pale wood and lager beer. For example, the OED records its use in the 19th century poetic to describe the flowers, "a variety of clay ironstone coal measures", "color raw silk", and breed ray.Varieties Various sub-blond hair was defined to describe someone with blond hair more accurately. Common examples include the following: blond / Lanen: when it differs from other varieties, "blond" itself refers to the light, but not without a trace whitish blond red, goldgold, or brown; This color is often described as "Flax". yellow: yellow-blue ("yellow" can also be used to refer to hair that is dyed yellow).Platinum blond or towheaded: whitish-blond; Almost all platinum Blonds have children. Even though the people in the Northern Europe. "Platinum Blonde" is often used to describe the bleached hair, while "towheaded" generally refers to the natural blonde hair colorsr. sandy blond gray-hazel or cream-colored blond. Gold Blonde: the darker the rich, goldgolden blond. Strawberry blond, Venetian blond or honey blond: blond or reddish blond.umazano dishwashing blond: blond with dark patches of goldgolden blond and brown. ash-blond: ashen gray or blond. bleached blond, bottle blond or peroxide blond terms used to refer to artificially dyed blond hair. Evolution blond hairNatural lighter hair dye is the most frequently occurring in Europe and les in other areas. In northern European populations, the emergence of blond hair is very common. Hair color gene MC1R has at least seven variants in Europe giving the continent a wide variety of hair and eye colors. Based on recent genetic research carried out at three Japanese universities, the date of the genetic mutation that resulted in blond hair to insulate Europe from about 11,000 years ago during the last ice age.The typical explanation found in the literature for the development of light hair is asociated with a request for the synthesis of vitamin D deficiency and seasonal Northern Europe is sunlight. Lighthter skin due to the low concentration of the pigmentation, thereby more sunlight to trigger the production of vitamin D.In this way, the high frequency of the light in the hair as a result of the Northern light adaptation of the skin to the lower levels of sunlight, which is a decreasing prevalence of rickets with vitamin D deficiency causes. Darker pigmentation at higher latitudes in certain ethnic groups such as the Inuit can be explained by the higher proportion of seafood in their diet. Because seafood is high in vitamin D, vitamin D deficiency would not create a selective presure for lighter pigmentation in this populaciji.Alternativna hypothesis presented a Canadian anthropologist Peter Frost, who claims blond hair very quickly developed into a special room at the end of the last ice age by sex selection. According to Frost, the appearance blond hair and blue eyes, and in some northern European women that they stand out from their competitors at a time of fierce competition for scarce males.The theory was defined by history and geography of human genes (1994), he says, blond hair became dominant in northern Europe, beginning about 3000 BC, the area now known as Lithuania, the recently arrived language Proto-Indo-European immigrants ( the Kurgan hypothesis), and the property has rapidly expanded during sexual choice in Scandinavia. As mentioned above, the theory asumes that showed men women with blond hair more attractive.Now is the hypothesis that the researchers that blond hair evolved more than once. Posted May 2012 in science, the study of people from the Solomon Islands in Malaysia noted that the change of amino acid in TYRP1 produces blonde hair. Relation to ageBlond hair is most common in light-skinned infants and children, so much so that the term "child blond" is often used for very light brown hair colorr. Babies can be born with blond hair even among groups where adults rarely have blond hair, although a natural hair usually falls out quickly. Blond Hair usually turn darker with age, and many children\'s blond hair turns light, medium, dark brown or black before or during adulthood.As blond hair usually turn brunette with age, natural blond hair rare and represents approximately 2% of the world population. Geographical distribution Europe Blond hair is most common in Scandinavia and the Baltic countries, where it is really blondism believed to have originated. Pigmentation both hair and eyes is the easiest of the Baltic Sea, and these regularly and almost concentrically increases around this region with countries such as England, Scotland, Sweden, Norway, Denmark, Netherlands, Germany, Finland, Estonia, Latvia, Lithuania, Poland, Belarus, Ukraine, Rusia, etc. generally have a higher proportion blond people from countries further south in Europe.In France, according to the source, published in 1939, blondism is more common in Normandy, and les frequently in the Pyrenees and the Mediterranean seashore; 26% of the French population has blond or light brown hair. 2007 Study of French women showed that until then was about 20% blonde, but half of those blondes completely fake.Approximately ten per cent of French women natural blondes, of which 60% bleach their hair a lighter shade of blond.In Portugal, 11% of the population shows traces blondism, peaking at 14.3 to 15.1% in Povoa de Varzim, Northern Portugal. In northern Spain, 17% of the population is blond, but in southern Spain, is only 2% of the blonde. In Italy, the geneticist 20th century Biasutti, 12% of Italians show different shades of blond, but regional contrasts are pronounced with increasing phenomenon in the northern and central regions (Veneto, Friuli, Valle d\'Aosta and Bolzano), where the figure can reach 15% - 20% and reduce the phenomenon of the south as in Sardinia, where only 1.7% exhibited blondism and, with the exception of Benevento and its surroundings, where blondism reaches 10 to 14.9%, as compared to other southern regions, where the average is about 2-7% . Africa Blondism is also a common phenomenon among the Berbers of North Africa, particularly in the Rif region and the Kabyle region. Blondism frequency differs among the Berbers of 1% between Jerban Berbers, 4% between Mozabite Shawia Berbers and Berbers, up to 11% of the Kabyle Berbers. In South Africa, an important population of WhiteWhites, mostly from the Dutch and English descent, blondes may represent 3-4% of the population of South Africa.Number blond naturally mummified bodies of ordinary people (ie not correctly mummies) dating Roman times was found in FAG el-Gamous cemetery in Egypt, "Of those whose hair was maintained 54% were blondes or redheads, and the percentage grows to 87 % if added light brown brown hair colorr. " Excavations have been ongoing since 1980. burials seem to be collected with brown hair colorr.Oceania Aboriginal Australians, particularly in the west-central parts of the continent, have a high frequency of natural blond to brown hair, because that 90-100% of children with blonde hair in some areas. Attribute the Australian natives is primarily asociated with children. The maturity of the hair usually turns darker brown, sometimes it remains blond.
