Tony,
Don't worry, a large percentage of my transplanted hairs didn't fall out in my first HT, and I had great results. On my second, a large percnetage "did" fall out, and I'm still having great results. So whether they fall out or not doesn't mean a thing. The bandana should not have bothered things unless hairs stuck to the bandana and were pulled out. You would know from seeing the hairs and blood. The scar is still healing and will for a long time to come. Hope this helps. Good luck, and remember to be "patient".
