Migraine headaches can be debilitating, horrendous life-ruiners for many, and those of us who suffer with them know that there isn’t always an easy remedy; sometimes all you can do is lie down in a dark room and wait for your head to explode.

However, the FDA recently approved a headband called Cefaly which may help prevent those headaches, and many are curious as to how it works. The battery-powered device sends a small electrical current under the skin to stimulate the trigeminal nerve, which has been associated with triggering migraines. It’s the first of its kind, and in a study that included 67 people, those who used Cefaly showed a significant drop in migraine headaches than those who had a placebo.

“Cefaly provides an alternative to medication for migraine prevention,” Christy Foreman, director of the Office of Device Evaluation for the FDA, said in a statement. “This may help patients who cannot tolerate current migraine medications for preventing migraines or treating attacks.”

While anyone can get a migraine, women seem to be more prone to them–in fact, they are three times more likely to suffer from one than men–and often menstruation is blamed for the onset of the pain. However, stress and lack of sleep can also be triggers. And while there’s no one easy way to keep them at bay, many are curious about the new device and whether or not it’s right for them. Of course, a doctor’s consultation is always advised, but Cefaly is now available on Amazon for those who have a little money to spend. The average price range is about $426.
