Hair coloringHair coloring, or hair dyeing, is the practice of changing the hair color. The main reasons for this are cosmetic: to cover gray or white hair, to alter hair to create a specific look, to change a colour to suit preference or to restore the original hair color after it has been discolored by hairdressing processes or sun bleaching. Hair coloring can be done professionally by a hairdresser or independently at home. Hair coloring is very popular, with 50-80% of women in the United States, Europe, and Japan having reported using hair dye.
HairstyleA hairstyle, hairdo, haircut or coiffure refers to the styling of hair, usually on the human head but sometimes on the face or body. 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. The oldest known depiction of hair styling is hair braiding which dates back about 30,000 years. Women's hair was often elaborately and carefully dressed in special ways, though it was also often kept covered outside the home, especially for married women.
ShavingShaving is the removal of hair, by using a razor or any other kind of bladed implement, to slice it down—to the level of the skin or otherwise. Shaving is most commonly practiced by men to remove their facial hair and by women to remove their leg and underarm hair. A man is called clean-shaven if he has had his beard entirely removed. Both men and women sometimes shave their chest hair, abdominal hair, leg hair, underarm hair, pubic hair, or any other body hair. Head shaving is much more common among men.
HairHair is a protein filament that grows from follicles found in the dermis. Hair is one of the defining characteristics of mammals. The human body, apart from areas of glabrous skin, is covered in follicles which produce thick terminal and fine vellus hair. Most common interest in hair is focused on hair growth, hair types, and hair care, but hair is also an important biomaterial primarily composed of protein, notably alpha-keratin.
