Long Blond Hairstyles

Long hair is a hairstyle where the 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. In most cultures, it is more typical for women to wear long hair than for men to do so. An exception was however head hair, which was kept to provide thermal insulation of the scalp from the sun, to protect against ultra-violet radiation exposure, and also to provide cooling (when sweat evaporates from soaked hair). The ability to grow long straight hair, has been observed among homo spines sub-groups in less sunny regions further away from the equator. Relative to curly Afro-textured hair, straight hair allows more UV light to pass to the scalp (which is essential for the production of vitamin D, that is important for bone development). 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.
