How many years a hair transplant can last depends on the survival rate of the hair follicles, the care after the hair transplant and the individual condition of the patient, and should be analyzed on a case-by-case basis. The key to the success of hair transplantation is the survival rate of the hair follicles. If the hair follicles can survive successfully, the hair transplantation can be maintained permanently. The longer the time, the less active the hair follicles will be, which may cause ischemic damage, and the lower the survival rate of the hair follicles. In addition, if the patient is older and the body functions are at a weaker level, the activity of the hair follicles after hair transplantation will be reduced accordingly, and the situation varies from person to person. After hair transplantation, it is recommended to maintain regular work and rest, avoid staying up late for a long time, and try to eat less seafood or spicy and stimulating food. As long as you follow medical advice and maintain good habits, your hair can generally be maintained permanently after the implantation.
