Scabs/Crust on Scalp 2 months after Surgery

[Brandonny1]

Hi it’s been 2 months since my surgery. Yesterday when washing my head I noticed scabbing/crust in my crown area. I tried washing it out but it was hard and I had to put pressure to get the scabs off but with the scabs were attached hairs/grafts. Can this making the grafts not grow in since hairs were pulled out with the scabs/crust? I’ve attached a pic of what some of them looked like.
