  • In androgenetic alopecia, hormones related to testosterone (also called androgens) cause hair follicles to have a shorter than normal growth phase, resulting in hair shafts that are abnormally short and thin. 
  • Genetics also appears to play a role in the risk for androgenetic alopecia in women, although other factors (some of which remain unknown) may also be important 
  • All hair follicles are present at birth; throughout the lifetime each follicle grows and sheds single hairs in a repetitive cycle. 
  • At the end of this time, growth ceases and the follicle enters a resting phase. 
  • After three to four months in the resting phase, the hair is shed and the next growth cycle begins.
