If hair transplantation is performed by a trained and experienced surgeon, it can last a lifetime. This is because the transplanted hair follicles are genetically programmed to continue growing. The results of a good hair transplant are visibly long-lasting and are the most permanent form of hair restoration. The transplanted hair follicles take the genetics from where they were planted and continue to grow. However, a patient's age, lifestyle, hair type, and degree of hair loss can affect how long a hair transplant will take. This situation is completely personal.
