Hair loss is a natural daily occurrence. Every hair on your head adheres to a genetically programmed schedule that includes growth, resting and shedding. On the average 50 to 150 hairs are lost each day. But most hair re-grows because the follicle remains. When shedding significantly exceeds growth, baldness occurs. In 95% of patients, hair loss is inherited. Specifically, it’s the genetic coding that hair follicles receive during formation in the womb. These hair loss genes make certain hair follicles sensitive to the hormone dehydroepitestesterone or DHT. When this link is made the follicle begins to shrink. It is first noticed as thinning hair, since the hair follicle begins producing only a very thin, short hair. Eventually the hair follicle dies and permanent baldness occurs.
High levels of stress has been known to cause some hair loss, but it is usually temporary. Autoimmune disease, the use of certain drugs, illness and severe nutritional deficiency may also cause hair loss or promote early male pattern baldness. Trauma to the head accompanied by scarring can cause permanent damage to hair follicles. Even tight hairdos like braids can create tension that can inflame hair follicles, destroying them and stopping hair growth. But %95 of the time it is genetic. |
