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.

Over my heart, and your hair fall over my breast,
Drowning loves lonely hour in deep twilight of rest....”

“If I be false, or swerve a hair from truth,
When time is old and hath forgot itself,
When waterdrops have worn the stones of Troy,
And blind oblivion swallowed cities up,
And mighty states characterless are grated
To dusty nothing, yet let memory
From false to false among false maids in love
Upbraid my falsehood.”
—William Shakespeare (15641616)
