Where the bald area is large and the donor area does not have sufficient hair roots which can be extracted to cover the baldness. In this situation, body hair from the chest, arm pit and pubic can be transplanted to the head. However, there is no clear research or evidence of the body hair transplant to give lasting results and the hair to continually grow because the body hair roots are thin and have single follicle and do not grow longer than a centimeter in whole life.
So the drawback of Body Hair Transplant and the longevity and sustenance of the hair are shared with the client before the hair are implanted as a last option to fill the baldness on the head. The client is told in a transparent and honest opinion that the body hair may not grow or last on the scalp and the even the roots have just a single hair so there are drawbacks of Body Hair Transplant.
