specifically for hair loss due to androgenic areata, i've recently been doing some research about this:
in a general link about PCOS and the section of interest is here quoted:
Quote:
Dutasteride (Avodart®)
The long-awaited new 5-alpha-reductase inhibitor, dutasteride, received FDA approval late last year for treatment of prostate enlargement in men and became available in the U. S. in December, 2002. The enzyme it inhibits is the one which activates testosterone by converting it to DHT (dihydrotestosterone). DHT is the active form of testosterone in the hair follicle and so blocking its formation is a potential treatment for hirsutism (increased facial and body hair) and androgenic alopecia (scalp hair loss due to testosterone). It is possible that dutasteride can help acne also but it is too soon to tell. Finasteride (Proscar® and Propecia®) also inhibits this enzyme but dutasteride is much more effective.
The FDA approved labeling for dutasteride includes warnings that women should not even touch the tablets, let alone take them. However there are similar warnings for finasteride which has been used by women. The concern is that these medications, like any which block testosterone, could interfere with the development of an unborn male child. What this means is that these medications should not be taken by any woman who might become pregnant. An additional problem with dutasteride is that it may take as long as 6 months after a person stops taking it before it is completely out of her system. So avoidance of pregnancy is critical.
The studies on men’s hair loss suggest that dutasteride may work better than finasteride and, given how it works in the body, this should be the case. This means that in all probability it will work for female alopecia as well. For the reasons I’ve already discussed, dutasteride is not for most women with alopecia or hirsutism. However, it may be appropriate in special situations. No woman should take dutasteride without careful personal consideration. Any use should be in consultation with a physician knowledgeable about treatment of women with testosterone blockers. I have discussed dutasteride because it is important news for women with hirsutism and alopecia and many have been asking about it. However it is not for casual use.
Spironolactone (Aldactone®) will still be the first choice for many women with alopecia and hirsutism. However for those few women who do not get a good response to spiro and who will not become pregnant, dutasteride is another possibility. |
Maybe this is something you want to explore with your Doctor....
