Genetics and baldness
New studies and a more through understanding of the human genome confirm that male and female pattern baldness is a complex genetic trait.
There is evidence that [male and female pattern baldness] is genetically based, but we the precise inheritance pattern is not yet known (2007 data). It is not likely to be due to one gene or one gene mutation: it's likely to be due to multiple genes.
To understand male and female pattern baldness, it helps to understand the hair growth cycle, which is divided into three phases: the growth phase, the involution, or regression, phase and the resting phase. In hair loss, the sleeping phase gets longer and the growing phase gets shorter until it goes to sleep. This is mediated, in part, by increasing amounts of, and/or increasing sensitivity to, active male hormone, dihydrotestosterone (DHT). As a result of this altered growth cycle, hair shafts become shorter and thinner, a process called follicular miniaturization.
It's unclear what is happening genetically to bring about miniaturization.
