A hairstyle, hairdo, or haircut refers to the styling of hair, usually on the human head. The fashioning of hair can be considered an aspect of personal grooming, fashion, and cosmetics, although practical, cultural, and popular considerations also influence some hairstyles.

Throughout history, people have worn their hair in a wide variety of ways, largely determined by the fashions of the culture they live in. Hairstyles are markers and signifiers of social class, age, marital status, racial identification, political beliefs and attitudes about gender.

In many cultures, often for religious reasons, women's hair is covered while in public, and in some, such as Orthodox Judaism or European Orthodox communities, women's hair is shaved or cut very short, and covered with wigs. Only since the end of World War I have women begun to wear their hair short and in fairly natural styles.

In ancient civilizations, women's hair was often elaborately and carefully dressed in special ways. Women coloured their hair, curled it, and pinned it up in a variety of ways. They set their hair in waves and curls using wet clay, which they dried in the sun and then combed out, or else by using a jelly made of quince seeds soaked in water, or curling tongs and curling irons of various kinds.

Long hair is a hairstyle. 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 with the same length of hair in some of the same cultures would be said to have long hair.

Scientists view long hair as playing a large part in natural selection among many species, since long, thick and healthy hair or fur is frequently a sign of fertility and youth. As hair grows slowly, long hair reveals several years of a person's health status and reproductive fitness. Hair length is significantly correlated with female attractiveness, as rated by men as well as women. Hair length and quality can act as a cue to especially a woman's youth and health, signifying reproductive potential. The prevalence of trichophilia (hair partialism or fetischism) is 7% in the population, and very long hair is a common subject of devotion in this group.

Ways of life often viewed as more rigid, such as soldiers and religious cultures, often have explicit rules regarding hair length. For example, Buddhist monks shave their heads as part of their order of worship. Even outside religious structures, cultures often associate male long hair with ways of life outside of what is culturally accepted. Subservient cultures, for example, are sometimes detected by their rulers through hair length, as was the case with the Gaelic Irish under English rule and the Moors under Spanish rule in Medieval Spain.
