Causes of hair loss in men

The cause of male pattern baldness is not completely understood, but some factors include genetics, testosterone, and environmental factors. The medical term androgenic alopecia refers to the fact that testosterone (a type of androgen) is always found in the hair follicles of patients experiencing hair loss.

Genetics – androgenic alopecia runs in the family. Several genes (i.e. androgen receptor gene) may play a role in causing male baldness.

Natural aging is a normal cause of hair loss. Almost all men over the age of 80 experience some form of male pattern baldness.
