Post-operation, strange shedding? HELP!

[Traveller]

Hello, I had a 5780-graft transplant done approximately 11 weeks ago and I've been noticing some strange shedding when I rub my head. I've seen a lot of these drop off; my gut tells me that they are shed hairs wrapped in sebum, but I'm concerned as to the damage they're causing to my transplant. Veterans, is this normal?
