[Skin Concerns] itchy tan blobs coming off my scalp? Dandruff or lice or something else? photos enclosed

My scalp has been itchy the past week or so, and when I go to scratch the itch, I feel a small bump, maybe 1-2mm in diameter. I'm not sure what these are, as I've had dandruff before and usually that's just white flakes, and I've had lice, and these don't look like bugs. Has anyone encountered this before?
