Hair restoration using chest hair micrografts
The hair transplant technique is governed by the dictum of ‘donor
dominance’ which suggests that hair from any part of the
body can grow in any other part of the body when transplanted
just as it grows at its site of origin. This theory put forth
by Dr. Norman Orentriech in 1959 was the very basis of the hair
transplant technique revolution until it was challenged by Dr.
Hwang and his colleagues in 2002. They proved that the donor dominance
theory was not totally correct and that the hair growth was greatly
influenced by the recipient site anatomy and physiology.
There is a case study involving transplantation of hair from
the chest of a 65 year old man who had scalp hair loss and scarring
due to poor hair transplants he had undergone about 20 years previously.
Drs. Ray Woods and Angelina Woods Campbell have successfully grafted
about 1500 grafts harvested from his chest region and enlightened
hair surgeons to an alternate donor region for hair follicles.
They have formulated a technique called the micro single follicular
unit extraction in which individual follicular grafts are harvested
to minimize donor site scarring and can then be used to correct
poor hair transplants. The donor site can be the conventional
scalp area or from the temple, nape, chest, abdomen and/or back.
In this case study the donor hair was harvested from the temple, nape and
the chest; and temple and nape hairs were used to create the hair line and
the chest hair used to cover the crown region. Since the harvests were individual
follicular units, no suturing or bandaging was necessary. The transplanted
hairs showed a survival rate of more than 90% and the growth rate was also
higher as compared to the donor site chest hairs original growth rate.
This method suggests a way to overcome non availability of donor
hair when there is considerable hair loss and the conventional
donor site, the scalp regions, do not have adequate hair density
for cosmetic reconstruction and correction.
