Dear Dr. Rassman,
Does a young man (mid twenties) who has been on Propecia for a few years run a high risk of permanent shock loss in the recipient area after an HT surgery? Also, will the HT speed up the normal balding process?
Usually, Propecia will protect a man against shock hair loss and acceleration of your hair loss, but alas that is a general rule and not everyone follows that rule. It is about 90+% predictable. Those at greatest risk for acceleration of hair loss are the young men who have very active miniaturization going on and are showing fast-track balding in process.
