I mentioned this in class last night (had been meaning to for ages) as my hair is coming out hugely.
Whenever I brush, or run my hands through my hair, lots comes out, and as for the shower, urgh!
But, having said that, I don't look as if there's noticably less there.
My LLC said the same - on SS, our bodies slow down less vital functions such as nail and hair growth. Once we start food again, we have a spurt.
