Chickie, you should've had at least two staples in that (or sutures). Seriously. Scalps don't get a lot of air and can take forever to heal properly, not to mention they're incredibly vascular.
You can always have someone else suture it for you - it's really not that hard to learn and the supplies aren't that difficult yo find. I'd recommend you find yourself the equipment if you're going to be without decent insurance/money for a copay for a while.
Of course, you could let me know how much your copay is and I'll take care of it for you. (I mean that, btw. I'd rather be out a couple of hundred and know your noodle is intact than have you go without medical care).
