Hair Loss?
I had RNY and had hairloss at about 2 months out. It was pretty thin until about 11months or so. I didnt do anything special.. just dealt with it, made sure to take my vitamins and hoped it would come back. So far so good.. I am over a yr out and it seems back to just about normal. I did have pretty thin hair to begin with, so.. not sure how much that matters, but it is definately more noticable.
good luck!
