Hi Kristina,
I am 2 weeks post op and I will say that some of my hair has been falling out, but not in big pieces like strands when I am washing my hair and more seems to come out when I brush my hair. I will say though that my hair was healthy but not 100% healthy due using chemicals in my hair like relaxers and hair color, but before the surgery I had it pretty much under control. I been taking Vitamins and hope that it will help and I have also read on here that the Vitamin Biotin is suppose to be really good to help with hair loss however I haven't been able to find it in chewable or liquid form.
As for excessive body hair I have never heard of that and have not experienced it and I really hope I don't lol.
Hope this helps you out.
