What makes hair grow naturally in the human body??

Hair is an outgrowth of dead cells from the body and grows only on mammals. Insects and spiders have what looks like hair on the surface of their bodies. These are actually bristles formed from their exo-skeletons.

Each hair cell is formed mostly from a type of protein called "keratin." Like all proteins, keratin is formed of chains of amino acids. Keratin makes the miniature skeleton inside all epidermal cells, hair cells, nail cells and feathers by weaving a type of cell basket around the nucleus. The hair-forming cell is called a follicle.

Humans have head hair and three kinds of body hair:

Lanugo is present only on fetuses.

Vellus hair is the fine, fuzzy hair present on most of the body.

Terminal hair is vellus that has been transformed by testosterone into coarse, curly "adult-type" hair.

Individual hairs have periods of growth and dormancy. While growing, hairs are long and bulb-shaped. During the dormancy period hair growth stops and the base of the hair shrinks. Then a new hair grows from the follicle and the old hair is shed. Head hairs grow for a long time and to more-or-less length. Body hairs grow for shorter periods and to shorter length before being shed.

The proportion of vellus to terminal hair on the body, as well as the texture and number of hairs in the head, is determined by the gender of the person and by the genetic tendency to be hairy inherited from their parents. Hair growth is also affected by age, by disease and by culture.
