As my physician brother-in-law says – Your hair doesn’t fall out when your hyper,
it becomes brittle and breaks off. I had RAI about 2 weeks ago so I don’t know about
hair loss from hypo (falling out or breaking off). He said as you go hypo you may notice
some shedding – not to the point of baldness, of course and it is reversible (I assume he means
when you stabilize).
