Most hair transplants are performed in men and women who have lost their hair because of age-related pattern baldness. But sometimes hair transplant surgeons restore hair that has been lost due to surgery or an accident. These hair transplant procedures, which are often more complex than standard hair transplants, are known as corrective hair transplants.

Women who have facial cosmetic surgery make up the bulk of corrective hair transplantation, says Edwin S. Epstein, MD, a hair transplant surgeon in private practice in Richmond, Virginia and Virginia Beach.

During a facelift, incisions are usually made near the hairline at the temple and run down to the front of the ear and behind the earlobe to the lower scalp. After removing fat and tightening muscle, the surgeon pulls the skin back, trims the excess and stitches the tissue together. The hairline is therefore pulled back on the head and hair loss may occur due to scarring. In men, the sideburns are often lost and women can lose their bangs. The hair loss may be especially problematic for women who like to wear their hair off their face in a ponytail.

Likewise, a forehead lift, also known as an eyebrow lift, can lead to hair loss because incisions are usually made at or behind the hairline and the skin is then pulled back. In men who are bald, the incision may be made at mid-scalp. Newer brow lift techniques leave less of a scar and cause less hair loss, but some people may still require a hair transplant.

"The goal of hair transplantation in these situations is to recreate and dense up the hairline," explains Bob Leonard, DO, founder and chief surgeon of the Leonard Hair Transplantation Association in Massachusetts and Rhode Island.

People may also seek corrective hair transplantation if hair loss has occurred as a result of trauma such as an accident or burn. The surgeon may perform hair transplants in the upper lips of men who had cleft palates repaired as babies, so that they can grow a mustache. They also do a lot of corrective procedures in people who had hair transplants performed with outdated plug techniques. These less precise procedures left wide spaces around each plug as well as scarring in the donor area in the back of the head.

Corrective procedures are more challenging procedures than standard transplants. Dr. Leonard says that's why it's particularly important that people find a hair transplant surgeon who has a great deal of experience performing transplants on a variety of patients.

When transplanting in a scarred area, surgeons have to be extra cautious about how close together they place the tiny grafts of hair to ensure that the hair is properly nourished. Hair growth in or near scarring may also be slower than it is healthy tissue, but Dr. Epstein says, "transplanted grafts often attract a blood supply, and that makes subsequent transplants work better."

People having this kind of transplantation may therefore require one or two additional procedures. In most cases, surgeons say, people who are patient and have enough donor hair are very satisfied with their new look.

"In people who have had a disfiguring scar, it doesn't always take a lot to make a dramatic improvement," Dr. Epstein says. "For them, a hair transplant offers a huge change in what they see in the mirror."

Why have a hair transplant?
Men get hair transplants to achieve a more or less permanent correction of hair loss in order to restore a more youthful self-image and improve self-esteem.

Who can get a transplant?
Any person with noticeable hair loss-including thinning hair and bald areas-and whose remaining hair is capable of growing in a transplanted location (called a donor-dominant condition), is a candidate for hair transplantation. A donor-dominant condition is one in which transplanted hairs are able to survive at a new location, and will live and produce hairs as they would have in their previous location.

The most common condition treated is so-called male-and female-pattern androgenic alopecia (hereditary hair loss). However, other conditions such as scarring disorders resulting from injury, diseases, or previous surgery of the scalp, can also be treated with hair transplantation.

When should a hair transplant be done?
A hair transplant can be done any time after there is sufficient hair loss in a particular area-such as the front, middle, or top of the scalp-so that noticeable thinning is present on casual examination. Hair loss actually begins long before it is noticeable; Approximately 50 percent of the hairs in a given area are lost before noticeable thinning becomes apparent.

How is a hair transplant done?
A variable sized section of living scalp containing live hair follicles is removed from the back of the head (donor area) and subsequently microdissected into small follicular unit grafts that are implanted into small surgically prepared recipient sites in the balding area (recipient area). The surgical sites heal in 7 to 14 days, and after a delay of 8 to 12 weeks, the transplanted hairs begin to produce new hair shafts.

Where is a hair transplant done?
Hair transplants are done in an outpatient setting. Patients walk in and walk out the same day. They are given oral, or in some cases inhalant or intravenous sedation, followed by local anesthesia to the donor and recipient sites.

What are the main difficulties experienced by a patient before, during, and after a hair transplant?
The main problems encountered by patients before hair transplantation are usually concern about the cosmetic down time in the postoperative period, and varying degrees of anxiety about potential discomfort during and after the procedure. During the procedure, the patients often become restless due to the prolonged time required to achieve the results and because of this, sometimes have difficulty refraining from talking and moving, which makes the procedure more difficult for the surgeon and the assistants. Finally, after the procedure, the patients experience variable degrees of discomfort at the donor site and variable degrees of swelling of the forehead that resolve in a few days. Also, patients often experience self-consciousness caused by the tiny scabs that are present in the recipient sites.

Which regions of the scalp are best suited for hair transplantation?
The frontal scalp and the midscalp are the areas best suited for microsurgical hair restoration. The so-called bald spot (vertex) can also be corrected, but is somewhat less desirable.

Can a completely bald head be completely restored by hair transplant surgery?
The answer is no, but this is a trick question. Obviously, a completely bald head cannot be transplanted, because it has no donor hair to transplant! Even a very bald scalp cannot be completely transplanted since the size of the donor area and the number of hairs present are smaller than the potentially bald area on the top of the head. However, if the potential donor site is sufficiently large and reasonably dense, a surprisingly large number of hair follicles are available for transplantation to the top of the head, and fairly large areas of balding scalp can be covered adequately with hair that is both natural and reasonably dense in appearance.
