I have been dealing with bouts of TE for about three years. This is the only year I have dared to let it grow. I have been shaving my head within an inch of my scalp the years prior. About 8 mos ago I started supplementing with Ferritin when I got my bloodwork done and it was a wimpy 23. I have heavy periods (that's getting better) and while I am not recommending other take this action, I decided to supplement even though my dr wrote it off as normal. So in April, I started shedding again. But it was different, it was much less that before, and there has been a lot of weak, thin hairs being shed (strangely enough they were nearly as long as the thicker, normal hair I shed too) and not so many thick ones. I have read that miniaturized hair does not grow past 3 inches. I have seen several that were 5 inches long or more.(My hair is just past my ears, that is about 8 inches) I consulted a different doctor and he said this: "the fact that you see less of a shed each time and you are losing fine weak hair means your TE is getting better" So there you go. there are other things I have done, and still more to do. At least I have some clue as to what is going on. I will post pics for all to see the stages I went thru.
