I’m a scratcher and worried about a hair transplant

I will use hair fibers when I go out, and if I take a quick shower before going to bed, there would still be some fiber that I didn’t get out. I wake up and notice black fibers under my nails which means I’m actively scratching my head during sleep. I am planning on doing my surgery in a few months and I’m worried about scratching while I’m sleeping. What can be done to stop this? Other than tying up my hands I can’t think of anything else

Discipline! Realize that if you scratch your grafts out, you will lose a lot of money and possibly introduce infection. I have seen this just twice in 16000 surgeries.  Both men were told to wear mittens.
