Ok, I know I'm really late to this convo, but have you considered you might have Sjogrens? I think I have Celiac and Sjogrens, because I have been trying to figure out what's going on with my hair since I went gluten-free in January. It's dry and breaks off all the time, and is falling out a lot and my curls have changed. I first found a thread that someone mentioned Sjogrens Syndrome on and I looked it up. I've been suffering with classic SjS symptoms for years, dry desert-like mouth at night with perfect teeth until my 30's then suddenly an onset of cavities, dry eyes when waking, really bad hand feet circulation issues. I haven't been diagnosed with either, but I do have one confirmed auto-immune disease and a family full of them, so I don't think it's too far of a jump. I have been using Wen for years, but noticed after going gluten-free that it doesn't seem to help as much as it used to, which makes me wonder about the wheat in it. I hope the maxi hair vitamins help me.
