Well, definitely give the major protein reduction a try, for sure!!
Falling out... Hmmm... You haven't recently had a baby have you??
Is your hair just shedding more than normal? Or is it really coming out in clumps?
Have you seen a Dr? Had your thyroid checked? All that?? I would say that should be an important next step. The dry and frizzy problem could be a separate issue to the hair loss. It's best to rule our any medical issues, for obvious reasons, so you might do that soon.
