Do I have to use propecia to maintain transplanted hair?
The answer is no, you do not have to use Propecia in order to maintain transplanted hair. Transplanted hair is permanent. You may also want to read the following Hair Loss Q&A Weblog which will give you more information on this.
However, many first-rate hair transplant physicians will recommend the use of Propecia in conjunction with a hair transplant in order to maintain whatever natural or native hair you have left – that is, hair that has not been transplanted. Hair in the “safe zone” which is the hair on the sides and back of your head where hair is taken from (called the donor area) is not genetically predisposed to Dihydrotestosterone (DHT) – the hormone responsible for hair loss.
Keep in mind that hair loss is unpredictable and some hair loss sufferers simply are not good candidates for a hair transplant, especially if they are not on hair loss medication to prevent further natural hair loss. I also encourage you to read the following thread: What should I consider when researching hair transplant surgery on our hair restoration discussion forums.
I hope this helps.
