Why Do Some React Better to Propecia Than Others?

I read a recent message from a 22 year old who has had a great experience with Propecia in only 3 months. I’m a 22 year old with slight thinning on top/thinning at the crown in the last 15 months and I’ve been on Propecia for 3 months too. BUT I have seen NO noticable difference in my hair density or hair count. Why do some men react better to Propecia than others? (I don’t have massive amounts of testosterone in my body either)

The rate of hair loss differs from individual to individual. The genetic factors vary with the person as well. A DHT blocker only impacts one of the factors that cause genetic hair loss. Unfortunately, not everyone responds to it the same way, but I believe that it has value in every man losing his hair from genetic factors. In some men, it reverses hair loss, in others it just slows it down or stops it, but there is a losing battle here and sooner or later as the genetic factors will dominate the hair loss equation even for those young men with these wonderful results. The goal for the DHT blockers is to alter the natural course of the hair loss (extend the balding process over many more years that it would normally occur). Hopefully, the extra time will allow the next breakthrough treatment for hair loss to become available (whatever it is).
