Yes. When a hair transplant is performed carefully and with attention to detail, the surgery increases the density of hair in the area treated. Hair is removed from the permanent donor area and moved to an area with hair loss. The transplanted hair will behave in this new region, as it would have in its original location. To be clear, this hair is “relatively permanent” in that it will gradually thin as a person ages, but will not disappear completely. Thus, the effects of the hair transplant are long lasting.
Of course, there are situations that can result in an unsuccessful transplant: poor planning by the surgeon with respect to the blood supply and density of sites, poor dissection technique by technicians, sub-optimal storage of the grafts outside the body and/or traumatic graft placement. Modern transplant surgery utilizes very small grafts, which are especially vulnerable. Therefore it is particularly important to be certain that the surgeon performing the hair transplant is well-trained and has a similarly excellent staff of technicians, who have the training and time to prepare and place the grafts with the utmost care.
