What are the factors which affect cosmetic appearance in transplantation?
The cosmetic look after transplantation is due to total bulk or volume of hairs.The total volume of hairs is given by the formula volume of multiple cylinders( hair is a cylinder) is nהּr2h where n+ number of hairs, הּ= pi 3.14, r =radius, h= height or length of hairs. Of these, the only factor which is under patients control to increase volume is length. So grow the hairs long.
