My doctor found out I had Hashimoto's from my hair loss, December 2004. How that I am on thyroid medication, since Sept.2007, I continue to have hair loss and have lost 1/2 my hair. 1/8 off my hair in the last 3 months. Is there any way I can stop the hair loss. I am using Levothyroxin 25 and one possible side effect is hair loss, my interist is sending me to a skin doctor in over a month. Do you know what might be the reason for the loss and would a skin doctor be able to help? I had blood tests done this week and my internist found nothing wrong. MaryLouiseB
