I know how u feel. I lost quite a bit of hair since my last 3 surgeries over 2 years ago. It takes time to grow back. Try not to get stressed out over it. Stress also causes hair loss, but the anestethesia is the worst culprit. Eat gelatin for your hair & nails. Use a wide tooth comb too. Cut it short & it will look thicker. At least you r in good company!
