The scalp skin normally changes testosterone to another hormone called dihydrotestosterone. In balding men it seems that the hair follicles become too sensitive to dihydrotestosterone and react by shrinking over time. Normally a single hair should last around 3 years, but as hair follicles shrink, the hairs become thinner and shed more often, until they get so short and thin that they no longer grow out through the skin.
