Long hair
Long hair is a hairstyle where the head hair is allowed to grow to a considerable length. Exactly what constitutes "long hair" can change from culture to culture, or even within cultures. For example, a woman with chin-length hair in some cultures may be said to have short hair, while a man would be said to have long hair.
Long lustrous female hair is generally rated attractive by both men and women across cultures. The prevalence of trichophilia (hair partialism or fetishism) is 7% in the population, and very long hair is a common subject of devotion in this group.
Humans, horses, orangutans, and lions are among the few species of mammals that may grow their head hair or manes very long. Humans are believed to have lost their fur 2.5–3 million years ago as hominids when transitioning from a forest habitat to the open savanna, as an effect of natural selection, since this development made it possible to run fast and hunt animals close to the equator without getting overheated. Head hair was an exception, which was a survival trait because it provides thermal insulation of the scalp from the sun, protects against ultraviolet radiation exposure (UV), and provides cooling (when sweat evaporates from soaked hair). The ability to grow straight hair has been observed among Homo sapiens sub-groups in less sunny regions further away from the equator. Relative to kinked Afro-textured hair, straight hair allows more UV light to pass to the scalp (which is essential for the production of vitamin D, which is important for bone development).
The ability to grow very long hair may be a result of sexual selection since long and healthy hair is a sign of fertility.[need quotation to verify] An evolutionary biology explanation for this attraction is that hair length and quality may act as a cue to youth and health, signifying a woman's reproductive potential. As hair grows slowly, long hair may reveal 2–3 years of a person's health status, nutrition, age, and reproductive fitness. Malnutrition, and deficiencies in minerals and vitamins due to starvation, cause loss of hair or changes in hair color (e.g. dark hair turning reddish).
Anthropologists speculate that the functional significance of long head hair may be adornment, a by-product of secondary natural selection once other androgenic/somatic hair (body hair) had largely been lost. Another possibility is that long head hair is a result of Fisherian runaway sexual selection, where long lustrous hair is a visible marker for a healthy individual. For some groups or individuals, however, short hair is the selected trait.
By seven to nine months, infants can tell the sexes apart based on hair length, vocal pitch, and faces.
Ways of life often viewed as more rigid, such as soldiering and religious discipline, frequently have explicit rules regarding hair length. For example, Buddhist monks shave their heads as part of their order of worship. Similarly, religious men with long hair is exemplified in modern Paganism, among Nazarites in the Hebrew Bible (Samson being a well-known example) and among the Sikhs. Other cultures may view male long hair negatively; historically, some conquering groups have used the long hair of conquered people as a symbol of their imagined "otherness" or inferiority, as was the case with the Gaelic Irish under English rule and the Moors under Spanish rule in Medieval Spain.
East Asian cultures have traditionally associated unkempt hair in a woman with an irresponsible attitude, as women in East Asia were expected to tie up their hair in styles such as the ponytail, plait, or any bun, as a symbol of responsibility.
