Answer 2

Hair forms in a pouch-like structure below the skin called a hair follicle. What we see as hair is actually the hair shaft, which is the keratinized, hardened tissue that grows from this follicle.

Humans have more hair follicles per square inch of skin than most higher primates, including chimpanzees and gorillas. Because most of this hair is fine and pale (called vellus hair), it usually isn't visible to the naked eye. Consider this: the forehead has more hair follicles than any other part of the body. The thicker, fully pigmented hair most people consider "real hair" is called terminal hair. This hair is found on scalp, eyebrows, legs, backs, underarms, and genital areas. This is the hair the Light Sheer diode laser treats.

Answer 3

Hair outside of your head and body is indeed dead. This is because there is no longer a stream of nutrients leading to it and keeping the cells alive, nor are these cells reproducing. However, hair grows through the reproduction of the cells from within the skin and under where you see it, pushing the older cells out of the body.

Answer 4

Hair is a product of the hair follicles which produce hair cells at the root of the hair shaft. As the new cells are formed they push the older cells out of the follicle which causes the older cells to die and this is what becomes the hair we see - the hair we see therefore is never 'alive'
