Androgenetic alopecia (”male-pattern baldness,” “female-pattern baldness”)
Everyone loses hair, but men do it better–faster, earlier, and more extensively.
Doctors refer to common baldness as “androegentic alopecia,” which implies that a combination of hormones and heredity (genetics) is needed to develop the condition. (The male hormones involved are present in both men and women.)
Male-pattern baldness
Even men who never “go bald” thin out over the years. Unlike those with reversible telogen shedding, those with common male-pattern hair loss don’t notice much hair coming out; they just see that it’s not there anymore. Adolescent boys notice some receding near the temples as their hairlines change from the straight-across boys’ pattern to the more “M-shaped” pattern of adult men. This normal development does not mean they are losing hair.
