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: The majority of women present with diffuse hair loss (i.e. thinning all over) rather than the patterned hair loss seen in men (where the hair is localized to the front and top of the scalp).

Diffuse thinning presents two problems for a potential hair transplant candidate.

The first is that there is no permanent area where the hair can be taken from. If hair is taken from an area that is thinning, the transplanted hair will continue to thin after the procedure, since moving it doesn’t make it more permanent.

The second problem is that since the areas to be transplanted are thin, rather than completely bald, the existing hair in the area of the hair transplant is at some risk to shedding as a result of the procedure.

When women have a more defined pattern (i.e. more localized thinning on the front part of the scalp with a stable back and sides), they can make excellent candidates for surgery. This pattern occurs in about 20% of women. A small percentage of men have diffuse thinning and are, therefore, poor candidates for a hair restoration surgery as well.

A: In the International Journal of Cosmetic Surgery and Aesthetic Dermatology (Vol. 5, Number 2; 2003), a study on low level laser therapy (LLLT) was conducted which indicated that there was a 55% increase of growth (hair count) in the temporal area as well as 64% in the vertex of the female subjects who were treated with LLLT for hair loss. The study also indicated a 74% increase in the hair counts of the male subjects in the temporal area and 120% in the vertex region. These results would initially indicate that LLLT works better in men than in women, but there were four times as many men in this study so the results might be different in a larger test group.

However, even in this notably smaller female group, the tensile strength of the hair increased dramatically over the tensile strength observed in the male subjects after treatment. This would indicate that, at least in this study, there was not only an increased hair count in women, but the tensile strength of that hair was greatly improved as well. This would be initially indicative that LLLT may be found to be more beneficial to women than to men.

It is important to note that this study was published in 2003. Further studies need to be conducted to confirm the initial results and to further elucidate the possible mechanisms of low level laser light therapy in both men and women with alopecia. As important, long term data needs to be accumulated to show the continued efficacy of this treatment. It had been our clinical experience that LLLT is not as effective as one would assume from the results of the initial studies.

The article — Can Lasers Stimulate a Hair-Growth Spurt? — discusses the efficacy of the HairMax LaserComb and low level laser therapy (LLLT) and also touches on Dr. Schweiger’s main area of expertise, the diagnosis and treatment of hair loss in women:

Eric S. Schweiger, a clinical instructor of dermatology at Mount Sinai Medical Center in New York, says the LaserComb helps grow hair, but adds that effects are often modest, typically take at least six months and aren’t seen in all patients.

The only home laser device cleared for hair growth by the Food and Drug Administration is the LaserComb, which claims to increase hair growth in men. While used by Dr. Schweiger and others for women, the device isn’t FDA cleared for them; a clinical trial is continuing, the company says.

Exploring Your Options:

Hairstylists, impressed with how realistic the “new” transplanted hair looks, recommend doctors to clients who are tired of hiding their hair loss with layers or high- and lowlights. “I’ve seen bad jobs,” said Seiji Kitazato, the creative director at Frédéric Fekkai on Fifth Avenue, who refers clients to a few surgeons. “But now you can’t even tell.”

Still, not every woman of the millions who suffer from hair loss is a candidate. Underlying conditions, including anemia and thyroid problems, that are temporary, treatable or affect the scalp rather than the hair, must be dealt with before a transplant can be considered. If a transplant is ruled out, sufferers must rely on wigs, hairpieces or styling tricks.

What’s more, “most medications can cause hair loss, some more frequently than others,” said Dr. Robert M. Bernstein, a clinical professor of dermatology at Columbia University who has a restoration center in Manhattan.

A transplant is an option only for a woman who has a thick enough area of hair from the back and sides to “donate” to a more paltry part of her scalp. But many women don’t experience this kind of localized balding; instead their entire head of hair thins out during menopause or as they age.

Buyer Beware:

So the incentive to treat any and all comers is high. “It’s a big problem,” Dr. Bernstein said. “You shouldn’t go to someone who will give a transplant to anyone who walks in the door.” If your condition is not properly assessed, you could permanently shed more hair after surgery than you gained, he warned, or if the hair transplanted wasn’t stable, “it would disappear.”

Before Hair Transplant Surgery:

If you’re suffering hair loss, see a dermatologist first, not hair transplant surgeons, said Dr. Robert M. Bernstein, a dermatologist in Manhattan who specializes in hair restoration. After determining a cause, dermatologists can offer advice about options from the medical to the surgical. Many women with hair loss try Women’s Rogaine, a solution with 2 percent minoxidil that is applied to the scalp, twice daily. Others prefer Rogaine’s foam for men, because it has 5 percent minodixil, dries quickly and feels less greasy. (But even the women’s formulation warns to discontinue use if facial-hair growth occurs.)
