About long hair

Long hair is a hairstyle where the head hair is allowed to grow to 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 with the same length of hair in some of the same cultures would be said to have long hair.Long lustrous female hair is generally rated attractive by both men and women across cultures.[1][2] In most current cultures, it is more typical for women to wear long hair than for men to do so. An American study shows significant correlation between hair length and age, which indicates that younger women tend to have longer hair than older women. A significant correlation was also found between women’s hair length and hair quality. Moreover, hair quality was correlated with the women’s perceived physical health. Consistent with principles of evolutionary psychology, these results indicate that hair length and quality can act as a cue to a woman’s youth and health, signifying reproductive potential. The correlation between the woman’s hair length and marital status, or number of children, was however not more than to be expected from the correlation between hair length and age.[6]
Biological significance

Scientists also view the ability to grow very long hair as a result of sexual selection, since long and healthy hair is a sign of fertility and youth.[5][need quotation to verify] An evolutionary biology explanation for this attraction is that hair length and quality can act as a cue to youth and health, signifying a woman’s reproductive potential.[6] 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 causes loss of hair or changes in hair color (e.g. dark hair turning reddish)
