My hair is also very thin and fine. I have eaten bread crusts (best part) all my life !!
We sound very much the same---we always ate the bread crust---it was just what we did---my hair has gotten thinner as I grow old---and it has always been fine---had a bit of curl in the back since my teens---a long time ago----gray is in it, too---some places will not take gray---so I am still researching---thanks for sharing--GOD bless you!!!
