Male baldness is a sensitive topic even for the most burly and health myths about what actually causes it do not help. According to the American Hair Loss Association, approximately 80 percent of men experience some level of hair loss by the age of 50. For women, that figure is closer to 50 percent.
So what it is that actually causes 85 percent of the male American population to deal with hair loss? Genetics. Androgenetic alopecia or common male pattern baldness is the result of your genes. For most men, hair loss is caused by hair follicles with a genetic sensitivity to Dihydrotestosterone (DHT).
Dihydrotestosterone is an endogenous androgen sex steroid and hormone. It is derived from testosterone and is a sex hormone that contributes to the development of male sex characteristics such as body hair, a deep voice and muscle mass.
Hair loss occurs when hair follicles that are sensitive to DHT begin to miniaturize, shortening their lifespan which eventually leads to the follicle shrinking. Hair around the top and crown of the head are usually the first affected, leaving a horseshoe ring of hair around the sides and back. However, that hair too, can be affected by DHT.
While inherited genetics are the most common reason for hair loss, other factors such as disease, medication and in rare cases, stress, can also lead to the loss of hair.
For women who practice the 100-strokes per night, hair professionals warn against it, saying that although it won’t cause your hair to fall out, that much brushing can lead to cuticle damage and hair breakage.
