Hair Loss Overview
Hair loss is a part of the process of natural hair renewal and is usually seen on the head. Hair loss in different parts of the body is generally unnoticed and they have a different genetic program than scalp hair.
Hair loss is seen both in man and women but is more commonly observed in men. 25 % of men over the age of 25 suffer from this problem, while this rate increases to 50 % in men over 50.
The cause of hair loss has become more clear especially in the last few years.
The determining factor in natural hair loss is hair growth cycles. Each hair is genetically programmed to go through the phases of anagen growing phase, catagen transitional phase and telogen resting or shedding phase. Losing approximately 100 hairs a day is quite normal and as long as hair follicles continue to function, these hairs keep growing.
There are countless reasons for hair loss has. Excessive stress, connective tissue disorders, the use of certain medications, chronic diseases, malnutrition and problems related to the hormones could trigger hair loss. Hair loss is also seen in body parts which have been subject to physical trauma.
Genetic hair loss is the most commonly seen type of hair loss both in men and women. Hair follicles are genetically coded in the womb. Baldness genes make certain hair follicles sensitive to testosterone and follicular activities start to reduce.
This is first noticed when the hairs get thinner. Through the course of time, the follicular activity stops completely and baldness becomes a permanent state. This type of baldness has many names, including androgenetic alopecia, androgenetic hair loss, male-type hair loss, male-pattern baldness and male baldness.
