Great site. I am a long time reader, first time poster.
My question is this: Is it possible to use donor hair from a friend/family member with the same style hair your have if there not enough donor hair on a subject?
Hair could be donated from other people just like organ donation, but without drugs to suppress the immune response, it will be rejected. Patients who are receiving an organ transplant need to be matched before the surgery for antigen compatibility and stay on anti-rejection medication for the rest of their lives. If you have an identical twin, it will work because the hair has the same genetic code as you would have.
Here’s a clip from our NHI video about identical twins and hair transplantation:
