There is no contraindication to hair transplant in the healthy elderly patient. The present and predicted future extent of loss should be evaluated. Exceedingly mobile scalp is an advantage. Gray hair is most preferable. Remember that the transplanted hair retains the characteristics of the donor site, so there may be a color mismatch.
Density varies by donor site, with the midocciput usually of highest density.
Care must also be taken to avoid harvesting from the extreme inferior border of the occipital region, since these hairs will ultimately be lost with progression of baldness. Age under 25. The inferior border of the adult male hairline should be placed between 1 to 2 cm above this measurement, and in severe cases 3cm above. A retained forelock can complicate this measurement. The position of the apex of the frontotemporal angle is another important consideration.
