Can Lactulose cause hair loss?

I have been using LACTULOSE and was concerned if that is causing my hair to fall out? I have never experienced this before, I have also been suffering from anorexia for 20 years and have never had this problem, I am in treatment for my anorexia and am eating now, which has totally confused me as more than anything I thought that I should be having the nutrition and this shouldn't be happening, as before I was starving myself and this never happened, can vitamin cause hair lost and LACTULOSE
