Causes of hair loss

Everyone loses hair, little by little, up to 100 strands every day of their lives. However, if your hair loss exceeds your body’s production of new hair, you may already fear the worst. For ages, hair loss in women and male pattern baldness was blamed on lifestyle and improper hair treatment. Several few years ago, scientists pinpointed hormonal and genetic factors as being the principal cause of balding. Once you know the details of your own physical make-up you can take steps to slow or stop hair loss. For many people with severe genetic predispositions, little short of surgical hair transplantation will cover extensive balding.

It’s All About the Genes and Hormones

Heredity, aging, and levels of testosterone in the body all contribute to hair loss in women and to male pattern baldness. More than 90 percent of all male and female pattern hair loss is attributed to genetics. Female pattern baldness affects 20 million women in this country and is directly related to inherited characteristics. Male pattern baldness affects some 40 percent of American males and is directly linked to hormonal disposition. Researchers claim that the real culprit is the hormonal byproduct DHT (dihydrotestostrone). DHT in the body causes hair to thin out and stop growing. DHT also blocks renewal of active hair follicles in the scalp.

Other Factors Play a Role

Hormonal changes in the body as a result of birth control pills or thyroid disease can accelerate hair loss, as can excessive blow drying and shampooing. Stress, from life’s experiences or from illnesses can also hasten balding. People who braid or pull their hair can also contribute to their early hair loss.
