Why CEFALY Works

Most migraines involve the trigeminal nerve, the largest and most complex cranial nerve. The top branch of the trigeminal nerve can be accessed through the skin on the forehead.

An External Trigeminal Nerve Stimulation device (e-TNS), CEFALY sends tiny electrical impulses through a self-adhesive electrode placed on the forehead to stimulate the trigeminal nerve, reducing the frequency and intensity of migraine attacks.

Cefaly Device

One Device. Two Settings.


Use CEFALY at the onset of or during a migraine attack.


Use CEFALY daily.

Attach the CEFALY device to your forehead with the reusable self-adhesive electrode.

You will feel a tingling sensation created by tiny electrical impulses from the CEFALY device stimulating the trigeminal nerve.

Relief from an active migraine attack can be achieved in 60 minutes with CEFALY.

Daily 20 minute preventative treatment sessions can reduce the frequency and intensity of migraine symptoms.

The CEFALY device will turn off automatically at the end of your session.



What Does CEFALY Feel Like?

At the start of a treatment, you may feel nothing or a slight tingling sensation, almost like your hair standing on end. The sensation or tingling feeling increases gradually and spreads through your forehead and the front part of your head. After about 14 minutes, the intensity stabilizes and remains constant until your treatment session is over.
