It’s pretty grim when a hair restoration treatment results in less hair than what you started with. How can this happen? It has everything to do with follicle (hair) survival rate. We often hear the term “success rate” with hair transplants, but the “success rate” is often very misleading. If we think of “success” as future hair growth, then virtually everyone will have “success” as at least some of the implanted hairs will continue to grow.
What is more pertinent to know is the follicle “survival rate” which is the number of transplanted hairs that survive, to produce permanent hair growth.
