Finasteride has been proven to help halt hair loss, but it has also been proven to lose efficacy after a certain amount of time. If this medicine only works for a finite period, what is the point of centering ones hair transplants around its short-term benefits? I understand if a person in their 20’s maintains intake of this drug it would keep them with a head of hair through their 30’s, but in their 40’s it will stop working and by that time their donor hair might be all used up. For a truly permanent solution, wouldn’t it be wise to wait until balding reaches a static level, and then go in for a hair transplant?
Nothing is that simple. Hair transplants (while permanent) are not the only answer. Did you know that you can have irreversible acceleration of the genetic hair loss from hair transplants? This is especially true if you are rapidly and actively thinning and if you are in your early 20s.
Another reason is that everybody’s goals and expectations are different. Propecia may not be a permanent solution, but what if it give you an extra 10 years of good looking hair without surgery? This option may not be satisfactory for you, but there are many others who would rather not have surgery and wouldn’t mind taking Propecia.
