Hair is a filamentous biomaterial, 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 keratin. In many human societies, women predominantly grow the hair on their head long while men cut theirs short.

Famous quotes containing the word hair:
“West Germans are tall, pert and orthodontically corrected, with hands, teeth and hair as clean as their clothes and clothes as sharp as their looks. Except for the fact that they all speak English pretty well, they’re indistinguishable from Americans.”
—P.J. (Patrick Jake)
“... my mother ... piled up her hair and went out to teach in a one-room school, mountain children little and big alike. The first day, some fathers came along to see if she could whip their children, some who were older than she. She told the children that she did intend to whip them if they became unruly and refused to learn, and invited the fathers to stay if they liked and she’d be able to whip them too. Having been thus tried out, she was a great success with them after that.”
—Eudora Welty (b. 1909)
“The moles nested in my cellar, nibbling every third potato, and making a snug bed even there of some hair left after plastering and of brown paper; for even the wildest animals love comfort and warmth as well as man, and they survive the winter only because they are so careful to secure them.”
—Henry David Thoreau (1817–1862)
