Could you just wrap these around your own hair? Like could you un-loc it by rolling it the opposite way it's dreaded then just re-roll it around your hair?

Crochet dreads aren't spun, so they don't unroll. The dreads that are twisted - they wouldn't stay twisted around your hair though. You would want to braid them in with an SE or DE method. :)
