Why Does Transplanted Hair Grow in Hair Transplantation?

I am seriously considering a hair transplant.   I am curious as to why would new hair follicles would grow in an area that  did not support the original ones.   Ishair loss a result of the hair  follicles or the blood supply to the area?

Thank you for your inquiry,

Hair restoration surgery relies on the concept of “donor dominance”.    

Hair follicles are genetically programmed.   For those suffering from hereditary hair loss  (male pattern baldness/female pattern baldness), many hair follicles are susceptible to dihydrotestosterone (DHT) – the hormone responsible for genetic hair loss of hairs genetically predisposed.

When these hair follicles are taken from the sides and back of the head (the donor hair) and are transplanted to the balding areas (recipient area) – they grow because they are not genetically predisposed to the effects of DHT.  

This is called donor dominance.   When relocating genetically resilient hair to bald or balding areas, the hair will remain resilient.
