In recent years great change has occurred in the way many surgeons perform hair transplants. Our San Francisco FUT hair transplant clinic and others have adopted the use of the dissecting microscope to create hair grafts of the smallest possible size which retains the natural characteristics of hair growth.
By natural characteristics of follicular unit hair growth, we mean the pattern of hair follicles as they grow out from the skin. If one looks at the scalp with 5-10 powers of magnification, we see that hairs grow out of the skin in groups of one, two, three, and four hairs. The human scalp averages one follicular unit per 1mm and each unit averages 2.2 hairs.
Therefore a strip of scalp 1cm in width and 10 cm in length could yield 1000 follicular unit grafts (2200 hairs) for FUT hair transplant in San Francisco. This is the way nature grows hair, and the closest we can come surgically is to move hair in these follicular units in their natural groups, cutting away the non-hair-bearing skin between them, and then transplanting them into tiny slits on the top of the head.
With most balding situations, two or three graft sessions may be necessary to give maximal potential results. In many instances, one session may be satisfactory for a particular patient. We do up to 3400 grafts per hair transplant session. By keeping hair transplants as small as possible, yet keeping the follicular units intact, one can create a natural-looking appearance.
It should be understood, though, that the density with follicular unit grafting will mathematically fall short of the normal, pre-bald hair covering. We cannot give additional hair to a patient. We are simply moving the hair that is genetically programmed not to be bald. If one can achieve 60% of normal density for a particular area, the average eye cannot distinguish that from full density.
In performing large sessions of follicular unit hair transplants, it is necessary to have a team of physicians, nurses, and technicians who can do the labor-intensive tasks of harvesting the donor hair, performing a trichophytic plastic surgery closure of the donor site, cutting the donor hair under microscopes into hundreds (or thousands) of these small follicular unit grafts and then inserting them into precisely created slits made with various sized small needles in order to create a natural pattern for future hair growth.
At Pacific Plastic Surgery Group, we strive to deliver the best FUT hair transplant San Francisco has to offer. We offer intravenous and oral sedation to patients so they may be sleepy or unaware through a good part of the procedure.
If they do wish to drive themselves or take public transportation without assistance, we offer local anesthesia alone or with nitrous oxide. Nitrous oxide is the “laughing gas” used commonly in dentistry. We have the patient breathe the nitrous oxide while the local anesthesia is being administered, thereby making the injection of local anesthesia hardly noticeable. With either scenario, the operation is painless once the scalp is anesthetized. When sedation is used, the 3-7 hr. period of work is but a vague memory. Many clinics perform follicular unit hair transplants under local anesthesia only.
This allows the patient to be fully alert through the procedure and be able to drive himself home afterward. Often we do not put a dressing on the top of the head. A cap can be worn after surgery to hide any evidence of the procedure. We keep a supply of baseball caps for those who might not bring one. Most patients can wash their hair gently the day after surgery. The second day after surgery, they can gently shampoo and, on the third day, they may use their usual hairstyling methods. The stitches or staples used for closure in the back of the head are removed in eleven to fourteen days.
A few problems and complications can occasionally occur with follicular unit hair transplantation. The most frequently seen problems relate to swelling of the forehead, which can occur and subside within the first week after surgery, and small pimples that may form at some of the graft sites during the first three or four months after the procedure. The swelling, if it occurs, goes away spontaneously. The pimples or cysts that form are treated by simply opening them, if they occur. We have the patients return for inspection to be sure that these potential problems are addressed early. At Pacific Plastic surgery Group certain measures (injecting Triamcinolone with the local anesthetic) during surgery to lessen the incidence of swelling.
A common occurrence after large sessions of follicular unit hair grafts is temporary fall-out of previously transplanted follicular unit grafts or from some of the thinning, balding hair. Because of changes in circulation that occur from the many punctures in the scalp, some follicular hairs are shocked. By “shocked”, we mean that the blood supply is temporarily diminished, causing the hair to go through a premature hair-growth cycle where the hair falls out and re-grows again. If this happens, do not be alarmed.
The previously transplanted follicular hairs will all grow back, along with the newly transplanted follicular hairs. It should be emphasized that follicular unit hair grafts, when they are transplanted, take an average of three months before new growth appears above the surface of the skin, with some taking as long as nine months. Little crusts that develop and hairs that are in the follicular unit grafts, fall off within the first two to three weeks, but this and the shedding of other hairs is no cause for concern.
In the “old days”, prior to modern follicular unit transplant techniques, hair grafting was done with the larger grafts, which have pretty much been abandoned for the smaller follicular unit grafts described in this writing. These older style grafts, often referred to as “plugs”, often resulted in the “corn row” or “doll’s hair” look.
This was due to large grafts compressed into smaller recipient holes and standing out by themselves. By dividing the donor source into smaller follicular unit grafts, we spread the hair around more diffusely and, therefore, get a more natural non-compressed look. We try to prevent an appearance that looks either like a doll’s hair or a wall of dense hair.
