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.

A: It is redundant to take both.

However, you may not be taking the optimal dose of dutasteride which seems to be at least 0.5mg a day for hair loss.

Nakamura interviewed Dr. Bernstein for this weekly series that began in October, 2006. In issues No. 1 and 2, Dr. Bernstein explained the basic mechanism of balding for both men and women which are quite different in its causes, balding types, and progression of hair loss. The NY Japion’s readers were all very surprised by the fact that balding for men is actually related to genes on both the mother’s side as well as the father’s side of the family. Dr. Bernstein also shared his unique theory of why Japan’s Samurai had the uniformed bald look.

The column discussed post-op care after hair restoration surgery and explained the drug Propecia, a men’s oral hair growth treatment, minoxidil and some cosmetic hair products.

Reporter Nakamura was also examined by Dr. Bernstein and with the patient’s permission was allowed to observe a hair transplant surgery. Issues No. 3, 4, 5 are about the surgical hair restoration procedure known as Follicular Unit Hair Transplantation (FUT), a method that Dr. Bernstein helped to pioneer. By using the patient’s own hair, FUT can give totally natural looking results. The patient’s own hair starts growing where there was no hair before.

A: Although androgenetic hair loss is dependent upon normal levels of testosterone, it is not due to increased testosterone. It is caused by a sensitivity of the follicles to normal levels of testosterone.

So someone that is bald doesn’t have extra levels of male hormones and is not necessarily over-sexed.
