    Hi Tina,

    Just thought I’d share my experience with you regarding hairloss.

    I started shredding large amounts of hair 5 months after I started tapazole (aka MM). I mean I was losing 500 hairs a day. Had all my blood work done and everything came back normal. My endo and derm both determined it was temporary. While there are reports that MM could cause hairloss, my endo said it’s rare. My hairloss was likely caused by sudden significant weight loss from being hyper, loss of vitamins and I was very low in ferritin/iron. If it’s shedding now, the assault likely took place 3-5 months ago due to hair growth phase.

    Anyway, to answer your question, my hairloss slowed down after 6-9 months. Hang in there, I know it’s disheartening but if it’s not related to any other medical condition, it will stop.

    Ok, this is interesting. Some people are hit by hair loss AFTER taking MM, then the loss slows down and stop losing goes next... Will it ever grow back eventually? Just wonder.  (my experience: start taking MM 2.5 mo ago, hair loss, thinning occurred, no slowing down, no stopping... yet!)

    I have been on this medicine for a year now and my hair is still falling out, you need to find a way to stay as calm as you can. That is what I keep being told but my life is so stressful, I feel like between this 3 diseases that i was so kindly given plus about 4 more things happening to my body i will be a basket case real soon. but honey talk to your doctor and find out maybe you need to have a pituitary test done and see what your levels are with that. that's the big daddy of it all your in my prayers cause i hate this I have not only hyperthyroidism, i have hypothyroidism, plus Graves Disease, and Hashimato, plus like I said some more. and it is a freakin Roller Coaster that I want off of.

I hope everything your going through gets better, I really appreciate your comments and others on this forum they have really helped me a lot to understand this disease thank you so much for sharing your experiences with this.
