Can stress be a contributing factor, besides diet to her hair loss? I can imagine teaching as being stressful but how we handle it. Preaching to myself here too. Perhaps checking out seaveggies as a source of help as they lots of nutients too. Is she able to exercise to relieve some daily stress if that is the case, but I believe in exercise even if no stress? Just some thoughts to consider. Hope she gets relief. Fortunately for millions they are under wigs when they have lost their hair, but know hair loss regardless is embarrassing especially as female. In meantime, I encorage you to not give up and keep searching till the answer comes.
