Some facts about hair loss

Loss of hair does worry people. Hair loss may be a normal temporary response to something you have experienced, such as an operation or a fever, in which case there is nothing to worry about. The loss may also be an inherited trait, so you must do the best you can to compensate for the loss. Or, it may be warning you that there is a medical or nutritional imbalance. Therefore, the sooner you seek help, the better

Hair is mostly composed of proteins. It grows about 1 centimetre per month, which, compared to other tissues of the body, is very fast. However, it is slow if you are waiting for your hair to re-grow . Scalp hair has a life of about four years and grows within indentations in the skin known as hair follicles . There are about 1,20,000 follicles on the scalp. The production centre for the hair is the hair bulb, where cells are constantly dividing, and hence, pushing the cells above in an upward direction. Below the hair bulb is the papilla which serves as the communication link between the hair and the rest of the body. The body’s blood supply circulates through the papilla and provides the nourishment necessary to keep the hair growing. Blood is the means by which many things are transported through the body. Because the blood transports things to and from the hair papilla, the hair itself is influenced by various factors. Indeed, the hair is so sensitive - due to its high rate of growth - that hair loss may be the first sign that something is wrong with you internally. more on hair loss
