this must feel very distressing. i hope to at least offer some reassurance. hair loss in women is not uncommon. that said i do think you should either return to your health care provider for follow-up testing or see a different doctor. the benefit of returning to the provider you saw last time is that he or she has your medical history and past test results for comparison. many conditions including thyroid issues can cause hair loss. just because they didn't show up on your lab work a year ago doesn't mean they won't show up now. you also should know that there is a condition called "female pattern baldness" that affects a number of women but this doesn't usually show up until a woman reaches her 40s. i wish you all the best in finding out why your lovely locks are falling out!
my hair has been falling out for almost a year now. i'm 26 yr old female. my blood tests came back normal. along w/excessive shedding my hair has been very dry. i haven't changed the way i treat my hair. i do see growth but shedding is so excessive that my hair thinned considerably since last yr. i have used spironolactone for acne 2 1/2 yrs ago. i have been off it for a little over a yr. didn't experience any bad sideeffects w/spiro. i'm not on birth control. i also have been experiencing low sex drive. my gp didn't have an answer for me. i feel hopeless<negative_smiley>
