Skin biopsies symptoms and conditions

Hi Everyone,
My experience with Mirena is still causing me distress, and I had it taken out on 9/1/08. I've been Mirena free for 5 months now, and still waiting for my hair to grow back. I do see some small, short hairs around my hairline, and I'm hoping that it's growing back, but maybe it's breakage? Any thoughts?
Here's my story: I have always had very heavy periods, so after one botched ablation two years ago, my doctor suggested Mirena. I had it placed in June, 2008. Almost exactly 3 months later, I figured out why my hair was falling out. Every time I brushed my teeth, I noticed how thin my hair had suddenly become. You could see each individual hair from the front of my hairline backward about 2 inches - each individual hair surrounded by lots of space! There was hair loss at the temples as well. I had my thyroid checked first, because my mother has a thyroid problem. My bloodwork was fine. I thought maybe my last highlight/foil might have caused it...but it was not breakage, it was an all-over thinning out. I finally realized that the only thing different was the Mirena, so I insisted it come out immediately. My doctor told me that at 45, I should expect thinning hair, which was probably the cause, not the Mirena. I told him to JUST GET IT OUT!
I really wish I had researched the matter beforehand, but am thankful that I put two-and-two together in a matter of months.
If anyone else has experienced hair loss, please post. We have to get the word out!
