scab

Hi it’s been now two months since my transplant and yesterday when washing my hair I noticed scabs/crown in my crown area and when I tried to wash them out they wouldn’t easily come out and so I had to put pressure on removing the crust/scab but connected to it where hairs/grafts could this have...

When I run my fingers through my hair I occasionally feel a crusty tiny bump on the temples or vertex (back top) of my scalp. If I pick it off, it doesn't hurt and it's usually a small crusty red cluster/dot. What is this? Is it normal? I don't use conditioner, only Head and Shoulders...
