Any words of advice would be most welcome. As I sit here typing this, I'm crying uncontrollably. My hair has been thinning out for about 1.5 years. When it started, I would remember so many hairs falling out in the shower. For the last year or so, the shed has stabilized and is not abnormal, but my hair is still thinning out aggressively. I started seeking out treatments about a year ago and was diagnosed with hypothyroid. Between August 2008 and February 2009, the doctor wasn't sure so I wasn't on any medication. My hair continued to thin out, but not too much. In March 2009, I started taking levothyroxine (thyroid hormone) and then switched to Synthroid two months later. Since then, my hair thinning increased so dramatically that I cannot hide it on the top anymore. It is really bad and progressing at a crazy speed - I have thinned out SO much over the last 3-4 months that I am absolutely devastated every time I take a picture. All this time, I'm not seeing much actual shedding in the shower or on my pillow, but visually it's getting worse and worse. I went to see Dr. Redmond in New York two weeks ago and he said that I'm probably not hypothyroid. I'm weaning off Synthroid now. But the hair thinning is progressing. Even though Redmond said that levothyroxine/synthroid do not cause the hair thinning, I am now looking back at pictures in January and February and I had a lot more hair. He put me on 20 mcg of Yaz and 200 mg of aldactone (generic: Spironolactone). My question is, if you have experienced this type of hair loss which I suspect is Synthroid-related, have you seen regrowth? I am devastated to think that Synthroid might have caused the aggressive thinning and that it could have been avoided. I can't stop crying, I am in such despair.
