Review (5/5): Get migraines? Buy this!
I suffer from miserable migraines and there are very few products, prescriptions included, that I can find relief from. These are at the top of the list. They feel just like a damp and cool cloth on your head minus the dripping and they take hours to lose their cool. These have been a complete lifesaver for me.
Additionally, I have extremely sensitive skin and was concerned that having any sort of sticky gel would make me break out or leave a residue. These don't create any problems. Even if you get hair stuck it slides out easily.
