Have been on Levoxyl for the past two years and have been having ...

I also have been on Levoxyl and have a cycle of extreme hair loss, about 50-55 hairs per shower. Yes, I count the individual hairs! Mostly in the back of the head (common for thyroid medication). I found a few years back that eating a "Clean Diet", makes all the difference in the world. If you look up the key words, "Clean Eating" online, it should direct you to several health food/fitness sites. It basically means, eating unprocessed food, drinking lots of water and 6-7 small meals per day. I can't say if this is the sole reason my hair stopped falling out but, I kept a food journal and about 3-4 weeks on this diet, my hair stopped falling out and has since been normal. I hope this helps? Going off the medication will yield other results that are equally unpleasant, I would consult your doctor before doing anything drastic. Best of luck to all!
