Top 10 Longest Hair in The World 2012 May, Girls Having Beautiful Long Hair
Hair is a filamentous biomaterial, that grows from follicles found in the dermis. Hair is one of the defining characteristics of mammals, but is also found in other animals.
All natural hair colors are the result of two types of hair pigment. Both of these pigments are melanin types, produced inside the hair follicle and packed into granules found in the fibers. Eumelanin is the dominant pigment in dark-blond, brown hair, and black hair, while pheomelanin is dominant in red hair.[5] Blond hair is the result of having little pigmentation in the hair strand. Gray hair occurs when melanin production decreases or stops.

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.
