Human hair along with the nails is the only nonliving tissue in the human body. Hair like nails is composed mainly of a fibrous protein known as keratin, its composition chemically is nearly identical to that of the material making up the fingernails and nails on the feet. New hair is continuously sprouting as keratin builds up in the scalp, the health of hair is maintained by a plentiful supply of essential nutrients from the nutrient-rich blood which reaches the hair follicles along the scalp via numerous blood vessels-follicles are areas from which hair sprouts anew. The growth of hair is a continuous process and taken on average, the human hair grows approximately half an inch in a single month-this corresponds to the growth of nails. When hair falls off, another new growth usually replaces it, though it is not rare for people to shed up to a hundred hairs in a given day-people with hair loss problems can lose much more hair in a day then the replacement and baldness may result in such individuals. Normally hair problems begin when the hair becomes dry or brittle due to problems with the scalp, it can stop growing back altogether-in some cases, hair can become flecked with a lot of dead skin from the scalp called dandruff. This common phenomenon is brought about by the excessive flaking and shedding of skin on the scalp due to various reasons.Hair Problems |
