Save money making your own headache roll-on stick! Only two ingredients and it really works.
Put essential oil(s) in the roll-on bottle.
Add a carrier oil to the shoulder of the jar (don't overfill).
Put the roll-on top in place -- it helps to press it in with a towel, then screw the cap on top to get it all the way on.
