This hair loss question was answered by Dr. Glenn Charles of Florida who is a member of the Coalition of Independent Hair Restoration Physicians. His professional answer is below.
How often do patients ask hair transplant doctor to take hair from the unsafe areas of the sides and back of the head? Could this hair be susceptible to the effects of DHT (dihydrotestosterone) and use that for the front? Is this common at all? Thanks!
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.
