I found this study from a few years ago which demonstrates the importance of catching your hair loss (by using Finasteride) early: http://www.hairlosstalk.com/hair-loss-news/Article299.php
"Starting treatment earlier than 30 months should prevent irreversible collagen changes which can lead to loss of normal blood supply, miniaturization of the follicles, and disruption in the normal growth resting cycles" .......... "The result of this study is that any treatment of Androgenetic Alopecia is recommended to start earlier than 30 months from first signs of Androgenetic Alopecia. This should prevent irreversible collagen changes associated with "Fibrotic incapsulation" of most anagen HF in involved areas, which usually leads to loss of normal blood supply, innervation, and subsequent miniaturization and prevention of hair from normal cycling."
So, in conclusion, start Finasteride (or Dutasteride) as soon as you can, because if you wait too long (any longer than 30 months from the onset of symptoms according to the above research), you may well find yourself past the point of no return.
