Um, your hair loss may be part of other medical conditions, like PCOS(which has worse risk factors beyond hair loss), and alopecia (which could be permanent) in which case you should be going to your general practitioner and probably getting referred to an endocrinologist.
Just to add, teratogens affect fetal development in ANY fetus and esp. during the first trimester. Teratogenic defects are characterized by possibly being assymetric, whereas conditions that are chromosomal have some symmetry (although not all teratogenic defects are things that can be measure by symmetry or assymetry).
You REALLY have to be careful with things that aren't regulated by the FDA, b/c they lack the warnings (and haven't been tested AND dont' have consistent formulas and concentrations-anything that is regulated has to label a certain way, and has to use certain nomenclature). Any cosmetic or medical item in the U.S. is FDA regulated, but vitamins, supplements, essential oils, and a lot of things from oversees aren't vetted that way (but the European and Canadian vetting process mirror our own).
So Nizoral is also something else that shouldn't be used by people who are pregnant or trying to get pregnant but the insert will tell you that as will your pharmacist.
I'm not sure why people think that these things can only affect male fetuses, the issue is that they can alter cell development at the most basic level, which occurs in ALL developing embryos and fetuses.
Seriously ladies, when it comes to thing that involve bodily functions, health, or medicine, you should ask a doctor, and when you buy it, ask the pharmacist, b/c they have learned how these things work and who should or shouldn't use them. Pharmacists have really good knowledge of how drugs interact and affect your body, use them as a resource (but they cannot give medical advice!!)
As this thread shows, a LOT of BAD BAD information is being tossed around by people who clearly don't understand these things AT ALL!!
Sorry if anyone gets upset by that but the earlier part of this thread was really disturbing, and the fact of the matter is that by the time that you can even tell the sex of a baby, something like this supplement could have already caused DEVASTATING birth defects or miscarriage. You do not EVER want to mess with your own hormone levels when you are pregnant.
