I was having usual symptoms of hypothyroidism - fatigue, weight gain, dry skin, hair loss, etc. Have been on Levothyroxine for several months now and have seen improvements in all symptoms except hair loss. I'm also on Plavix (due to a TIA), which I understand can also cause hair loss. I started on it shortly before beginning to exhibit thyroid symptons. I've had breast cancer, so can't take estrogen. Testosterone test was normal, so that's not the cause of the hair loss anyway. It's substantial and is becoming embarrasing. I'm also taking supplements, including Fish Oil, which I understand also acts as a blood thinner. I'd like to stop the Plavix (which I assume is the problem) and increase the Fish Oil and perhaps add Vitamin E, also a blood thinner. Any comments or suggestions? (My doctor is not into natural supplements as an answer to medical problems.)
