Estimation of safe donor area in hair transplant surgery

Sir, estimation of the donor area for hair transplant surgery is essential to avoid the hair programmed to be lost to male pattern baldness and also to avoid the improper position of the resultant scar. It becomes more important when the donor area is limited. The shape and size of the donor area varies from person to person depending on the age, type of baldness and available area. The potential donor area must be assessed on logical and scientific basis. The careful history and examination of the patient is of utmost importance. Age of the patient is a key factor in planning the hair transplantation.
