title: Blond text: many children's blond hair turns light, medium, dark brown or black before or during their adult years. Because blond hair tends to turn brunette with age, natural blond hair is rare in adulthood; according to the sociologist Christie Davies, only around five percent of adults in Europe and North America are naturally blond. A study conducted in 2003 concluded that only four percent of American adults are naturally blond. Nonetheless, a significant majority of Caucasian women (perhaps as high as three in four) dye their hair blond, a significantly higher percentage than for any other hair color. Blond hair is title: Human hair color text: is found in average brown hair. It is most commonly found in individuals of Northern and Western European descent. Red hair ranges from light strawberry blond shades to titian, copper, and completely red. It is caused by a variation in the "Mc1r" gene and is recessive. Red hair has the highest amounts of pheomelanin, around 67%, and usually low levels of eumelanin. At 1–2% of the population, it is the least common hair color in the world. It is most prominently found in the British Isles. Scotland has the highest proportion of redheads; 13 percent of the population has red title: Human hair color text: of both. More pheomelanin creates a more golden or strawberry blond color, and more eumelanin creates an ash or sandy blond color. Many children born with blond hair develop darker hair as they age, with the majority of natural blonds developing a hair color of a dark blond hue by the time they reach middle age. Pregnancy hormones hasten this process. Natural light blond hair is rare in adulthood, with claims of the world's population ranging from 2% naturally blond to 16% in the US. Blond hair is most commonly found in Northern and Western Europeans and their descendants but title: Red hair text: Red hair Red hair (or ginger hair) occurs naturally in one to two percent of the human population, appearing with greater frequency (two to six percent) among people of northern or western European ancestry and lesser frequency in other populations. It is most common in individuals homozygous for a recessive allele on chromosome 16 that produces an altered version of the MC1R protein. Red hair varies in hue from a deep burgundy or bright copper (auburn) to burnt orange or red-orange to and strawberry blond. Characterized by high levels of the reddish pigment pheomelanin and relatively low levels of the title: Blond text: Blond Blond or fair hair is a hair color characterized by low levels of the dark pigment eumelanin. The resultant visible hue depends on various factors, but always has some yellowish color. The color can be from the very pale blond (caused by a patchy, scarce distribution of pigment) to reddish "strawberry" blond or golden-brownish ("sandy") blond colors (the latter with more eumelanin). Because hair color tends to darken with age, natural blond hair is generally very rare in adulthood. Naturally-occurring blond hair is primarily found in populations of northern European descent and is believed to have evolved to enable
