Hair Loss In Women: Treatments That Work (cont.)
In addition, Reed says women should be aware that most specialists treating hair loss have special preparations that can reduce many of the side effects of the over-the-counter or prescription drugs by suspending them in milder preparations. In addition, most also have customized formulations that combine two or more significant ingredients, and often add natural "hair helpers" such as zinc and biotin, to increase effectiveness.
"This is why it's important that a woman visit a specialist in female pattern hair loss, because she is likely going to need some of these specialized preparations in order to obtain optimum results," says Reed.
Lastly, Ricardo Azizz, MD, reports many women have found help through the use of estrogen-dominant birth control pills -- oral contraceptives that work by overriding the high levels of testosterone and flooding hair follicles with enough female hormones to keep testosterone-related hair loss from taking place.
"Most birth control pills function similarly, but we do try to avoid the super low-dose pills because we want more estrogen," says Azizz, director of the Center for Androgen-Related Disorders at the Cedars Sinai Medical Center in Los Angeles. Among the brands favored by hair loss specialists include Yasmin, Demulen, Desogen, and Orthocyclen.
While a rumor has long persisted that birth control pills can actually cause hair loss in some women, Azizz says it's just not so.
"Birth control pills can cause a temporary change in the hair growth and shedding pattern, so if you are suffering from a non-hormonal cause of hair loss, and you take oral contraceptives, they might aggravate the loss, but they won't cause the loss," says Azizz.
Hope For The Future
Among the latest buzz in the alopecia (hair loss) community is a unique new process for regenerating hair growth via the formation of new hair follicles. Known as "follicular neurogenesis," it is a kind of cloning that attempts to generate "hair seeds" that may ultimately help new follicles to grow.
"Essentially the method takes a sample of your hair, sends it to the lab where the follicles are microdissected, and the cells the body uses to make hair are extracted and isolated," says Reed.
Those cells, he says, are then purified and cloned to make many cells, which are then microinjected back into the balding area where they will hopefully cause the cells to make more hair follicles.
While the system is still under development, Reed says that realistically it's many years from having a clinical application. In one study, published in Nature in 1999, a similar cloning system was shown to work on rodents. But to date, Reed says those specific results have not been duplicated.
A lot closer to reality is treatment with the drug Avodart (dutasteride), a cousin to the already popular finasteride (Propecia and Proscar) and also originally developed to treat prostate disease. The big difference, however, is that while finasteride helps block one enzyme involved in the conversion of testosterone to DHT, Avodart appears to block two -- and that may be a real boon to women.
"Propecia reduces body levels of DHT 50%-55%; Proscar reduces it 65%-70%, but Avodar reduces it up to 94% -- so the gain here is significant," says Reed.
Although still considered highly experimental for female pattern hair loss, it is currently being used in small in-office trials, and only in selected women who cannot get pregnant. Reed, who is one of the doctors testing the drug on women, says it is being tried on those patients for whom Proscar didn't work after one or more years of treatment. He is optimistic about the results thus far.
"It may turn out to be the best enzyme blocker for women we have," says Reed.
Finally, while hair transplants for men have long been considered a staple treatment, they were rarely considered appropriate for women -- mostly for cosmetic reasons. However, reporting in the November 2003 issue of the Journal of the American Academy of Dermatology, doctors from the Mount Sinai Medical School in New York City say that advances in transplant technology -- including less scaring -- combined with more realistic expectations, are now making this a viable option for women as well.
Rather than removing plugs of hair one by one and transplanting them to a different area of the scalp, the current techniques remove an entire strip of hair, then dividing it into smaller sections that are surgically placed precisely where the hair is needed -- even in between hairs that are still growing naturally.
Still, the experts advise that women should consider hair transplants only after a trip to a dermatologist, a diagnosis, and at least one round of treatment with medication.
