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:

    With girls, everything looks great on the surface. But beware of drawers that won’t open. They contain a three-month supply of dirty underwear, unwashed hose, and rubber bands with blobs of hair in them.
    Erma Bombeck (20th century)

    O Time and Change!—with hair as gray
    As was my sire’s that winter day,
    How strange it seems, with so much gone
    Of life and love, to still live on!
    Ah, brother! only I and thou
    Are left of all that circle now,—
    The dear home faces whereupon
    That fitful firelight paled and shone.
    John Greenleaf Whittier (1807–1892)

    But if a woman have long hair, it is a glory to her: for her hair is given her for a covering.
    —Bible: New Testament St. Paul, in 1 Corinthians, 11:15.
