Any Studies Showing Propecia and Minoxidil Cause More Hair Loss?

Have there been any test results that showed products such as Propecia or Rogaine can actually cause MORE hair loss? Both products after several months caused me to lose more hair more rapidly and I’ve read other people’s accounts of this happening, on this blog, as well as other sites. It seems that the FDA should study this if they’re going to license products. Thank you for your time!

There are no long term hair loss events reported from either drug, except for the people who have local allergic reactions to minoxidil. The short term loss of hair is thought to be the results of accelerated hair cycling and it reverses.
