Make sure you're getting enough Protein...my Mom and I both had surgery, she was able to stomach the protein supplements that were reccomended for the first few weeks post surgery and lost next to no hair. I on the other hand, could NOT stomach them and lost at least 1/3 of my hair, it's all back now and I feel great. But I was really glad I had super thick hair there for a while.
Good luck on your journey,
