along your hairline, down the back of your head across your shoulder from your neck to your end of your collarbone.... They hurt, I tried them once and since they hurt so bad for so long especially the ones from my eye brows, across the bridge of my nose, then around my hair line. When I got to my car I just sat and bald. I didn't have a Migraine when I got there but had a wicked one when I left. Tried it one more time and it was just as bad. They couldn't pay me too do it again. Good Luck with what you decide to do I hope it turns out positively.
