What is the common cause of male pattern baldness?

Male pattern baldness, also known as androgenetic alopecia, is primarily caused by a combination of genetic predisposition and hormonal changes. This condition typically arises from the influence of androgens, which are male hormones that regulate hair growth. In individuals genetically predisposed to this type of hair loss, hair follicles become sensitive to these hormones, leading to a shortening of the hair growth cycle. As a result, hair becomes thinner and eventually stops growing.

The genetic aspect indicates that if there is a family history of baldness, the likelihood of developing male pattern baldness increases. Hormonal changes, especially those related to testosterone and its derivative dihydrotestosterone (DHT), play a crucial role in this process by affecting the hair follicles negatively and leading to the cessation of hair production over time.

Thus, the primary cause of male pattern baldness is fundamentally rooted in these genetic and hormonal factors, distinguishing it from other causes that might involve external stressors or lifestyle influences.
