Dr. Bernstein was consulted for the article:

Hair transplant: A possibility if your hair loss is concentrated in specific areas. Hair follicles (in groups of up to four) are surgically removed from an area on your scalp where growth is dense and then implanted in the thinning patches. Since female hair loss is often diffuse, only about 20 percent of female patients with thinning hair are candidates, says Robert Bernstein, MD, a New York City dermatologist who specializes in these surgeries. (The price tag can run from $3,000 to $15,000.)

In October 2008 Dr. Bernstein appeared on the Oprah Winfrey Show, where he spoke about hair transplantation and gave a live demonstration featuring the hair transplant results of one of his patients.

A: Hair transplants work because hair removed from the permanent zone in the back and sides of the scalp continues to grow when transplanted to the balding area in the front or top of one’s head. The reason is that the genetic predisposition for hair to fall out resides in the hair follicle itself, rather than in the scalp. This predisposition is an inherited sensitivity to the effects of DHT, which causes affected hair to decrease in diameter and in length and eventually disappear – a process called “miniaturization.” When DHT resistant hair from the back of the scalp is transplanted to the top, it will continue to be resistant to DHT in its new location and grow normally.

A: The crown can be transplanted first in patients who have very good donor reserves (i.e., high density and good scalp laxity). Otherwise, after a hair restoration procedure to the crown you may not be left with enough hair to complete the front and top if those areas were to bald.

Cosmetically, the front and top are much more important to restore than the back. A careful examination by a trained hair restoration surgeon can tell how much donor hair there is available for a hair transplant.

A: Widened scars can be improved in two ways: they can be re-excised to make the scar finer, or hair can be placed into the scar to make it less visible.

Excising a scar works best when the original incision was closed with poor surgical techniques. In this case, using better closure methods can improve the scar. When the scar is the result of a person being a naturally “poor healer,” a wide scar will be the result – regardless of how the incision was closed.

I often approach the problem by excising a small area first, to see if I can decrease the width of the scar. If so, I would then proceed to excise the rest of the scar. If not, I would obtain hair using follicular unit extraction (FUE) — extracting hair in follicular units directly form the scalp — and place this hair into the scar. The hair placed in the scar can also be obtained from the edges of a partially excised scar.

If a wide scar that is thickened (called a hypertrophic scar) is also excised, it will usually reoccur and may result in an even worse scar. Because of this, thick scars should be flattened with injections of cortisone prior to removing. This will decrease the chance of a recurrence.

Flattening the scar is also important to permit the growth of newly transplanted follicular unit grafts.

A: Grafts are generally permanent 9 days following a follicular unit hair transplant procedure, so you may shampoo the flakes off at this time. If larger grafts were placed (with correspondingly larger recipient sites), the grafts will be subject to being lost for a slightly longer period of time. After 9 days, you may shave or clip the hair in the transplanted area if you like, but this will not affect the success of the hair restoration one way or the other.
