Hair Restoration: Temporary Fix or Permanent Hair Loss Solution?
Category: Common Questions , Donor Issues , Hair Restoration Physicians , Hair Transplant Surgery , Propecia (Finasteride)I have two questions concerning long-term hair restoration goals. Regarding medications, doesn’t Propecia lose its effectiveness over time? Also, what happens when patients’ donor hair starts to thin? I was told that hair from the “safe zone” eventually becomes susceptible to Male Pattern Baldness. If these things are true, how can anyone guarantee lasting results?
This hair loss question was answered by Dr. Cam Simmons of Toronto, Canada, who is a highly esteemed member of the Coalition of Independent Hair Restoration Physicians.

I know some patients who have taken Propecia (finasteride) since 1997 (before they met me) who feel that they haven’t lost more hair, and some who have had a slow decline.
Some hair follicles in the donor area may be affected by DHT, but most aren’t in most men. Take a look at the seniors you meet or pass in a day. In a few, you can see through their hair on the sides, but not in most. Some men can get generalized thinning of all of their hair in advanced age, called senile alopecia.
I just did a touch-up hair transplant for a 68 year-old man who had 4 sessions from 1976 to 1980 and the transplanted hair was still there. His hair was about 2 inches long, and the rows and rows of punch graft scars did not show. The scars made up about half of his 9mm wide, 30cm long donor strip, but we still managed to get 1408 grafts.

In my experience this is not very common. Most hair restoration patients trust the doctor to only take donor from an area that is most likely permanent. If a patient is already having hair loss or thinning hair and the doctor feels that it is due to male pattern baldness (mpb), it would not make sense to take donor tissue from an area that may be lost later.
