Hair

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:

    Nobody is saying that these people do not ultimately cease to be. And
    Sometimes their passings are even more painful than ours.
    It is just that so often they live till their hair is white.
    They make excellent corpses, among the expensive flowers. . . .
    Gwendolyn Brooks (b. 1917)

    do not sleep
    he wants to climb out of the toilet when you sit on it
    and make a home in the embarrassed hair do not sleep
    he wants you to walk into him as into a dark fire.
    Anne Sexton (1928–1974)

    Passing away, saith the World, passing away:
    Chances, beauty and youth sapped day by day:
    Thy life never continueth in one stay.
    Is the eye waxen dim, is the dark hair changing to gray
    That hath won neither laurel nor bay?
    Christina Georgina Rossetti (1830–1894)
