Where do the hair follicles for hair transplantation come from?

The hair follicles used in hair transplantation are usually extracted from the patient's own occipital or parietal regions.

Hair transplantation is a common treatment for hair loss. The procedure involves transplanting healthy hair follicles to the balding areas where they can regrow hair. The primary sources of hair follicles used in hair transplant surgery are the patient's own occipital or parietal regions. These areas are known as the "donor zones" because their hair follicles are resistant to the effects of androgen hormones. Harvesting follicles from the patient's own body avoids the risk of rejection and ensures natural and long-lasting surgical results.

It should be noted that hair follicle tissue is a non-renewable resource, so the donor areas will not regrow hair after extraction. Although harvesting hair follicles from the occipital region may leave minor scarring, the scars are usually covered by surrounding hair and do not significantly affect the individual's appearance. Patients are advised to choose reputable medical institutions for hair transplant surgery to ensure the success rate of the surgery and the survival rate of the transplanted follicles. After surgery, patients should also follow their physician's instructions for scalp care and dietary adjustments.
