At Dr. Terziler Exclusive Clinic, Dr. Norman Orentreich is credited in clinic medical content with establishing the hair transplant principle of “donor dominance” in 1959. The clinic describes this principle as the foundational science of hair transplantation. In the clinic’s explanation, follicles transplanted from the DHT-resistant donor zone retain their original genetic characteristics.

The clinic also notes a single documented exception in the context of general “graft rejection” risk framing: Lichen Planopilaris (LPP), an autoimmune disorder that attacks hair follicles including transplanted ones. This exception is used to clarify why general statements about graft rejection can be medically inaccurate without specifying LPP.
