For people who have balded significantly and have given up on hair growth solutions or they have find no success in regrowing hair, the last resort is to undergo a hair transplant.
What is a hair transplant? Basically the process involves the transplant of scalp follicles, which are still alive and functioning into the balding portions of the scalp. As a recap, people get bald, when their scalp follicles die and drops off, these seed of hair growth are then lost irreversibly.
However, the hair on our sides of the scalp are programmed for life! Hence to say, the follicles on the side of our head will last throughout our lifetime. Hair transplant will hence necessitate the transfer of these eternal follicles into the balding scalp for growth of hair at these balding regions.
Local anesthetic needs to be administered to the patient undergoing the hair transplant treatment for it will be a bloody affair... its like planting seeds, poke into the scalp and plant a seed.. its like sewing too. This is what I have watched from a video.
