My hair has been falling out at the root in clumps continuously for the past 9 months. It is very frail and thin now, my hair used to be so thick it would get stuck in my wide tooth comb! I got my thyroids tested and they are normal. I think my hair loss my be due to adrenal failure, but I don't know how this was caused. I've had type I diabetes for 13 years now, I'm 22. Does diabetes play a part in adrenal failure? How can I reverse this by cleaning/strengthening my adrenal glands?
