I don't have that problem with my hair, I lost all of it last Sept due to full brain radiation, lol. Now I am getting hair back in on the sides and back. My hubby told me this morning that I am getting my Dad's bald spot on top of my head. He always did the famous comb over to try and cover the spot, lol.
I'm sure I have not only knitted my hair into my projects but also spun it into my fibers as well. :)
I am always shedding and finding my hair all over the place.
