Thanks for all the information. Well if you say they look like knits, that would be it, and your history suggests it. This has come to you by sharing of combs and a lice can get to another scalp this way from one who is already infested with it.
Since you say that the knits are not particularly close to the scalp, it means that the lice infestation had occurred some time ago, and not that recent.
