]I am over 2 years out from having the Gastric Sleeve. I was using Rogaine for a little while, but it didn't do to much. I started taking 5000 Biotin and my hair started getting thicker and growing back, but I bagan getting adult acne, so I cut down to taking the Biotin only twice a week. Now, out of no where. My hair has began falling out again in astonishing amounts and I am right back where I started. Don't know why it started all over again and just don't know what to do next.
